AGRICULTURE HAS BEEN A KEY ELEMENT
INTRODUCTION
History of Agriculture
Agriculture has been a key element in the development of mankind as well as the
socioeconomic development of humans. Agriculture is believed to have begun simultaneously
around the world. Archaeologists have uncovered evidence of animal domestication and plant
cultivation in the Middle East, Asia, and the “new world” that is now called the Americas. This
evidence has been dated as far back as 7000 BC, which proved the historically important nature
of this subject. The four stages of human development are hypothesized to be (1) huntergatherer,
(2) herdsman, (3) farming, and (4) civilization. The change to herdsman or farming marks the
beginning of early production agriculture. The early stages of production agriculture are a result
of human intensification of the food gathering or propagation process. The more food sources
that could be encouraged by humans along with the discouragement of un-useful plants and
animals within a given area, proved to be beneficial to the needs of increasing populations.
(Encyclopedia Britannica, 2007)
Domesticated crops such as peppers and avocados were being grown in the Americas as
early as 7000 BC. Villages prospered and became widespread after 3500 BC when the
production of maize, or corn, began (Encyclopedia Britannica, 2007). It was farming and the
production of maize (corn) that created a bond between the early settlers and the Native
Americans who inhabited the area that is now the United States of America. This production of
food was not only key to their nutritional survival in the new land but also to their ability to
create a strong economic foundation. As settlers moved west, the ability to feed their families
became as important to survival as to the early settlers. This involvement in production
agriculture and the surplus of goods above the family’s need also allowed trade among
individuals to evolve.
The ability to feed and clothe oneself became a structural stronghold of the United States
national foundation. This production of food and fiber also formed the basis of many other
industries. Later in the civilization of the country, farmers became able to produce more than
their families could consume. It was at this point when others were free to take on tasks other
than food acquisition. The ability to manufacture clothing and textiles was a relatively new idea,
yet was still dependent on production agriculture for the inputs needed. The mass processing of
food products also evolved during the industrial era. Although this industry was still dependent
on production agriculture it allowed the nation to feed itself and also to embark on trade
negotiations with other countries. (Encyclopedia Britannica, 2007)
The agricultural industry of today incorporates traditional production agriculture with the
newer processing and finishing industries as well. Production agriculture has grown to include
fewer individuals who produce a greater total amount of product. The amount of agricultural
product produced outweighs the domestic need and allows for global trade.
The number of individuals currently employed in agricultural support industries
outweighs those in production agriculture jobs by sixteen percent (Gilmore & Whatley, 2006).
This employment number should continue to grow as individuals become less self-sufficient and
more dependent on fast, readily available food sources. Although the number of individuals in
production agriculture has decreased in recent years, the total number of people that are
employed in the agricultural industry has grown over time.
Agriculture Defined
Agriculture is the production of food, feed, and fiber by the process of growing and
harvesting plants, animals, and other life forms from management, cultivation, or tillage
practices. The term Agriculture is derived from the Latin term “Agri” for field and “Cultura” for
cultivation (Merriam-Webster’s Collegiate Dictionary, 1996). It is described as an art or science
of farming: cultivating the soil, producing crops, and raising livestock. Although the practice of
agriculture has traditionally been geared toward crop cultivation and the raising of livestock, it
has expanded to include other related areas. The current field of agriculture encompasses many
subject matter areas including agronomic crops, horticulture, aquaculture, animal husbandry,
food science, environmental management, and many others.
Impact of Agriculture
The field of agriculture spans a subject area much wider than one may perceive. In order
to estimate the importance of the agriculture industry to the United States, researchers have
calculated the cost of producing commodities and preparing them for consumers. Agriculture
production has increased, including both the propagation of a commodity and its processing for
human consumption. This growth can be associated with increased production technology and
the growing demand for food and fiber.
It has been noted that an estimated thirty-six percent of the world’s population was
employed in some form of agriculture in the year 2006. It can also be noted that twenty percent
of the U.S. population was employed in some form of agriculture related job which equaled
approximately twenty two million jobs in 2005. Fewer than two million Americans, or ten
percent of the total population, are actively engaged in farming with the remainder of the
employment being in the fields of science, marketing, research, and communication. Even states
with very little production agriculture present report a substantial portion of their citizens’
employment is in the food and fiber system. Employment opportunities are projected to continue
to increase across all fields of agriculture and related industries. The number of jobs in this area
will be greater than fifty-eight thousand positions by 2010, which equals between twenty and
twenty-five percent of the total employment in the nation. (Gilmore & Whatley, 2006)
Even with this small number of producers in operation, the American farmer is efficient
enough to produce over sixteen percent of the world’s food supply (Gilmore & Whatley, 2006).
The quantity of food produced in the United States has a profound impact on the world market
and on individuals within the global countries. The number of individuals that are dependent on
the production of food and fiber in the United States is immeasurable by any normal standards
due to the vast span of agriculture markets around the globe. National changes in production,
marketing, and management of resources not only affects citizens within this country but can,
and does, impact individuals in many other countries around the world.
New Developments in Agriculture
Due to the growing agricultural industry that mirrors the global population which it
serves, many new developments have evolved in recent years. These issues range from
environmental stewardship, biofuels, and food safety. These issues are only a few of the new
developments and issues that the field of agriculture deals with daily.
Environmental stewardship has become a hot topic in the field of agriculture. Many
outside the agricultural sector have the misconception that all agricultural practices have a
negative impact on the surrounding environment. This can only be expected when common
agricultural practices disturb the natural structure and evolution of the soil, water, and even air
surrounding production areas. The ability of producers to maintain the natural structure of the
environment is to their benefit since these actions have a relationship to increased productivity of
the land, which is reflected in the amount of yield that is produced from a given commodity. The
term sustainable agriculture has been used to describe the production of food, feed, and fiber
indefinitely without causing damage to the ecosystem (Merriam-Webster’s Collegiate
Dictionary, 1996). Sustainable agriculture has three main goals: environmental stewardship,
farm profitability, and prosperous farming communities. These goals have been addressed from
both the standpoint of the producer and the consumer so it is easy to understand why individuals
gravitate toward this type of agriculture. Although all aspects of sustainability are not fully
known, issues like erosion, runoff, nutrient depletion from the soil, and crop waste are all issues
that are included in the plan utilizing viable sustainable practices.
In recent years agriculture has evolved into new forms such as organic production
methods, biotech seed development, and bio-fuel development. These areas are of increasing
concern to the public due to their relatively new nature and the uncertainty of their influence on
the perceptions of the general public. Globalization, food safety, and land use are also topics that
are currently involved in heavy discussions and can be expected to gain momentum for many
years to come.
Social research has shown that unsubstantiated claims made against agriculture have
become linkages or truths in the brain. Unless this misinformation is corrected with new
information, adaptation can not take place due to the fact that this issue is not properly
understood. This informational linkage is very important to those educating the public about
agriculture and its importance. (Agriculture Council of America, 2008) Misconceptions are
often wide ranging and cover numerous issues. They also affect wide ranges of individuals due
to the domestic and international issues with which they are associated.
Importance of Agricultural Literacy
Due to the number of individuals that are impacted by agriculture by both employment or
for food and fiber, agricultural literacy becomes an important factor. Literacy can be defined as a
base level of skill or knowledge that one possesses that allows them to competently complete a
task (Sticht, 1975). This can also be the ability to competently respond to information and make
educated decisions. For the purposes of this study, agricultural literacy is the level of agricultural
knowledge that enables a true understanding of the industry and allows good social decisions to
be made with regard to this subject area (Frick, Kahler, & Miller, 1991). Agricultural literacy
includes an understanding of agriculture’s current economic, social, and environmental
significance to all Americans. The understanding includes knowledge of food and fiber
production, processing, and domestic and international marketing (Agriculture Council of
America, 2008).
Agricultural literacy campaigns have set goals and objectives that steer their actions.
These goals include increasing knowledge of the agriculture industry, informing citizens about
the employment opportunities that exist in the field of agriculture, and highlighting the role that
agriculture plays in the history of the United States. (Agriculture Council of America, 2008) The
ability to properly inform members of society about the truth regarding agriculture enables
individuals to observe educated decisions being made for the betterment of society.
The Issue of Perception
Although the basis for all reactions, decisions, and rulings are hinged on the knowledge
that one has, the manner in which information is utilized by individuals is definitely in need of
discussion. The increase of proper knowledge is theorized to have a positive effect on the public
perception of an issue. The extent to which perception affects decisions and reactions is in need
of review.
Many of the issues that face the agriculture sector today are relatively new. Research on
these issues is in progress and current information is readily available, yet in many situations the
time that is needed to make definite decisions is not as readily available. This leaves many
uncertainties and unanswered questions. This lack of knowledge is thought to cause the
perceived effects of these issues to be misjudged. Many decisions have been made based on
statements that may not be true to the fullest extent. The problem arises when misinformed
individuals make these types of statements based on their perception of an issue and allow these
perceptions to guide others along a similar path of misinformation.
Today, information can be found on any topic instantaneously due to the use of the
internet. The problem with this wealth of information is that in many instances the information
may not be true. At the onset of any type of risk perceived by the public, attitudes toward that
topic may become negative. Research and scientific findings that support the facts will not
change the decisions that many have already made based on the original perceptions. (Frewer,
Howard & Aaron, 1998)
Statement of the Problem
In a time when perception is the driving force behind the actions of many who dictate
future agricultural policies, evaluating the perception of individuals with regard to agriculture
and the practice of growing food and fiber has become increasingly important. Elected
individuals rely on public opinion to guide the decision making process that they must undergo
while doing their job. The opinions of their voters and the perceptions that they have obtained
can drastically affect the manner in which these elected parties handle public policy issues.
Research that allows us to understand the relationship between knowledge and perception, while
understanding the outlying factors that affect both knowledge and perception is needed.
Purpose and Objectives
The purpose of this study was to determine the knowledge and perception of the animal,
plant, environmental, and food sciences by the adult residents of Louisiana. The evaluations of
the knowledge levels and the perception levels were also compared to determine if a relationship
existed between these two factors.
This study had the following objectives:
1. To describe adult residents of Louisiana on the following demographic
characteristics:
a. age,
b. gender,
c. ethnic background,
d. location of residence (in a rural area, on a farm, in a town, in a city),
e. parish of residence,
f. occupation of the head of household,
g. highest level of education.
2. To determine the knowledge of the adult residents of Louisiana regarding the
following selected aspects of the agriculture industry:
a. animal science,
b. plant science,
c. environmental science,
d. food science
3. To determine the perceptions of the agricultural industry among adult residents of
Louisiana.
4. To determine if a relationship exists between knowledge of selected aspects of the
agriculture industry (defined as animal science, plant science, environmental science,
and food science) and perceptions of the agriculture industry among adult residents of
Louisiana.
5. To determine if a relationship exists between perceptions of the agriculture industry
and the following demographic characteristics of adult members of the general public
in Louisiana:
a. age,
b. gender,
c. ethnic background,
d. location of residence (in a rural area, on a farm, in a town, in a city),
e. parish of residence,
f. occupation of the head of household,
g. highest level of education
6. To compare the perceptions of the agriculture industry among adult residents of
Louisiana by whether or not the respondent had completed a college degree in an
agricultural or related field.
7. To compare the perceptions of the agriculture industry among adult residents of
Louisiana by whether or not the respondent had prior agricultural training (defined as
whether or not the respondent indicated that they enrolled or participated in any
agriculture course(s) during high school or college, such as FFA, 4-H, or other
activities).
8. To compare the perceptions of the agriculture industry among adult residents of
Louisiana by whether or not the respondent had prior agricultural experience (defined
as whether or not the respondent indicated that they are currently a member of
Louisiana Farm Bureau).
9. To determine if a model exists explaining a significant portion of the variance in
perceptions of the agricultural industry among adult residents of Louisiana from the
following measures:
a. knowledge of adult residents of Louisiana regarding selected aspects of the
agricultural industry,
b. age,
c. gender,
d. ethnic background,
e. location of residence (rural, farm, town, or city),
f. parish of residence,
g. occupation of the head of household,
h. highest level of education
Significance of the Study
The findings of this study were used to clarify issues that affect perceptions of the
agriculture industry by the adult residents of Louisiana. Measuring knowledge, perceptions, and
the correlation between these two variables will be valuable to several different groups and
organizations including land grant universities, farm organizations, and youth agriculture
programs.
The groups that will benefit from these results the greatest are the farmers and ranchers of
Louisiana. The most important impact that this study may have is to enable those involved in
production agriculture to know how they are perceived by the general public. This will allow
members of the agriculture industry the ability to combat inaccurate perceptions and explain
important issues. They are able to correct local conflicts based on untruths and battle national
issues that affect the productivity of their industry. Since the United States legislative system is
based on bills written to meet the perceived needs of the American people, the ability to correct
misconceptions about the agriculture industry will enable producers to ensure that legislation that
affects the daily activities of the agriculture industry is based on factual information.
The findings will aid in the creation of new programming by agricultural organizations
that will address the needs found in this study. This study will also measure knowledge in the
areas of animal, plant, environmental, and food sciences and indicate which areas are in need of
promotion to increase agricultural literacy. The identification of specific areas where agriculture
knowledge held by respondents is lacking will aid in the development of agricultural literacy
programming. This programming will also be guided by the determination of select
demographic groups that are in need of such programs. The development of public relations
materials that combat this negative perception could be a result of the findings in this study. The
proof of need for public relations in this area will also assist in gaining funding for such projects.
Membership in the Farm Bureau organization could also be of benefit if there was a noted
positive impact on perception by the public relations activities produced by the organization.
Farmers and ranchers will be more apt to join an organization that has beneficial implications on
their occupations and livelihoods.
The impact on perception and the perceived need for university studies has a direct
correlation to the basic funding of these areas of study. The negative perception of the
agriculture industry may cause elected officials to vote against funding due to the pressure placed
on them by the general public. For this reason, institutions that have agriculture study areas are
in a constant state of flux where perception can mean the difference between progression and
deletion.
This study was to show if enrollment in agriculture courses, participation in agriculture
groups such as 4-H or FFA, or obtaining a degree in an agricultural area significantly affects
perception of the agricultural industry. The findings, showing a positive influence on perception,
could assist agriculture programs in high schools in recruitment of new members by showing the
increase of information that is disseminated to members. This could also assist university
agriculture programs in structuring their recruitment materials to change the agricultural
perception of certain demographic groups. These findings will aid in recruitment for these
occupational majors.
It has been said that “knowledge is power”. Agriculture knowledge based on factual
information is not only powerful but warranted in situations such as policy making, public
relations, and organizational development. This study will assist institutions and organizations
with each of these needs and clarify the perceptions of the agriculture industry at hand.
A limitation of this study is the use of phone interview technique. Phone surveys have
been categorized as secondary forms of gathering information in the past. Inability to reach
target audience groups and shorter than necessary surveys are reasons against the use of phone
and mail surveys. The inability to denote the physical reactions of respondents to survey
questions was noted by Dillman (2007) as yet another shortcoming. The movement toward
utilizing cell phones as a preferred method of phone communication is also a bias. Those who
are adapters of this new technology are at risk of being excluded from this study.
CHAPTER 2
REVIEW OF RELATED LITURATURE
Agriculture in the United States
Agriculture can be defined as the cultivation or tillage of the soil in order to produce food
or fiber for human use. (Merriam-Webster’s, 1996) Although the “tillage of the soil” has been
in existence for thousands of years, agriculture has become ever more important in recent years.
This is due in part to the importance of food and fiber production with regard to national
security. The increased publicity in the questioning of agriculture and its role in the maintenance
of soil, water, and air quality has also raised the individual concerns of citizens. Agricultural
subsidies within the United States have also raised concerns of citizens in times of financial
downfall due to the large volume of money that farmers are provided through government
payments each year. These concerns may be new but are just part of the evolution that farming
has gone through over time.
Even before the American Revolution, a large percentage of colonists were farmers by
trade. These farmers were not merely self-sufficient tillers of the land but marketed and traded
excess food and fiber to others in order to meet the demands of those who held other
occupations.
At the turn of the century the agricultural economy in the U. S. consistently grew. From
1897-1910, prices for agricultural commodities climbed higher each year (Cochrane, 1979). The
period that was to follow from 1910-1919 was to prove to be an even greater positive economic
time. This was a period of time in which the standard of living for farmers grew significantly
higher (Hurt, 2002). World War I marks the beginning of the golden age as it encouraged
farmers to plant more crops, develop more land, and create a surplus that could be exported to
other countries. The farmer was no longer a price taker, but for the only time in history he had
buying and selling power equal to that of other industries. This time period was called the
Golden Age of Agriculture. The end of the golden age coincided with the great depression. This
period witnessed many farmers losing everything that they owned due to decreases in prices and
demand for goods.
The need for new innovations was evident in the 1920s and beyond. The unveiling of
hybrid corn and the use of chemical fertilizers after World War I made a dramatic impact on the
Midwest. Fertilizers gave way to pesticides, both of which are commonly used today. The
adaptation of mechanical tools was also a major portion of the evolution. The labor shortage
created by World War II caused many to purchase tractors and other mechanized machinery. All
of these innovations caused an increase in production and surplus in the markets. These
surpluses caused exports to begin to increase and the farm economy to improve dramatically
(Cochrane, 1979). The ability to demonstrate the proper use of this technology was also
beginning to blossom.
FFA Organization
Founded in 1928, the Future Farmers of America (FFA) brought together students,
teachers and agribusiness to solidify support for agricultural education. The FFA program was
started in 1928 by vocational education students in Virginia. Later that same year in Kansas
City's Baltimore Hotel, 33 young farmers charted a course for the future by forming the national
Future Farmers of America organization (National FFA Organization, 2009). These young men
realized that there was a need for bonding between agriculture students to allow them to share
common ideas, new technologies, and interests. They could not have foreseen how the
organization would grow and thrive.
Since 1928, millions of agriculture students - no one knows exactly how many - have
donned the official FFA jacket and championed the FFA creed. FFA has opened its doors and its
arms to minorities and women, ensuring that all students could reap the benefits of agricultural
education. In 1950, the 81st Congress of the United States, recognizing the importance of the
FFA as an integral part of the program of vocational agriculture, granted a Federal Charter to the
FFA. The organization’s name changed in 1988 from “Future Farmers of America” to “The FFA
Organization”, reflect the expanding career field of Agricultural Education. Today, the National
FFA Organization remains committed to the individual student, providing a path to achievement
in premier leadership, personal growth and career success through agricultural education. Now,
the organization is expanding the nation's view of "traditional" agriculture and finding new ways
to infuse agriculture into the classroom. (National FFA Organization, 2009)
Cooperative Extension Service
Following the establishment of the land grant college system by the Morrill Act of 1862,
the need for education of farmers and ranchers beyond the traditional classroom setting was
reviewed. This need led to the birth of the Cooperative Extension Service. The history and
formation of the Cooperative Extension Service dates back to the implementation of The Hatch
Act of 1887. This legislative piece established a cooperative bond between United States
Department of Agriculture and the nation's existing land grant colleges allocating annual federal
funding for dissemination of research to the general public. This funding came from the sale of
land that was granted to the states or territories by the federal government. This funding
established the regional and local experiment stations that produced research based information
that was relevant to the population that the station would serve. This was one of the ways to
improve the productivity of the farms and by doing this, build up the economy and also help the
communities (Kile, 1921). It was the driving force for the land-grant colleges to meet
agriculture's needs with regard to regional research.
Congress also passed the Smith Lever Act in 1914. This legislation, signed by President
Woodrow Wilson on May 8, 1914, authorized an additional level of cooperative extension work
between the Land- Grant Colleges and the United States Department of Agriculture. The act
bears the names of the congressmen who introduced it, Senator Hoke Smith of Georgia and
Representative A.F. Lever of South Carolina. It provided for the establishment of what is now
titled the Cooperative Extension Service. As a result of the Smith Lever Act, there are now
extension offices which serve to “extend" information developed on teaching campuses and
research stations across the nation. The Smith-Lever Act of 1914 specified that the work would
consist of “instruction and practical demonstration in agriculture and home economics to persons
not attending or resident in said colleges in the several communities”. The legislation also stated
that this instruction would impart information on said subjects through field demonstrations and
publications. (Encyclopedia Britannica, 2009)
The need for demonstration leaders led to the formation of the group of individuals
known as county agents. The county agents and the experiment station personnel understood the
delivery of innovation in production agriculture and performed this task exceptionally well.
They also understood the need for organization in the areas of marketing and policy. American
Farm Bureau President James R. Howard (1919-1922) noted that the county agents would
become and should become the right arm of the American Farm Bureau Federation due to their
involvement with members of production agriculture and their in-depth understanding of the
need that this potential organization would fulfill. (Kile, 1921) For many years after the
establishment of the local farm bureaus, county agents were a driving force providing leadership.
This evident strength of the county agents within the county farm bureau organizations began to
weaken after the organizations began to gain momentum. This separation from the extension
service and the county agents was assisted by many attacks on the non-profit, industry oriented
organization of Farm Bureau and its use of individuals whose salaries were funded entirely by
the state and local tax base. Even so, the county agent still remains an active part of county farm
bureaus and are included in many county Farm Bureau activities.
Since its inception, the Cooperative Extension Service has worked with the farmers and
ranchers of Louisiana to create the finest food and fiber production systems in the world.
Cooperative extension played a huge role in the adoption of new machinery, pesticides, and seed
varieties. Test plots that were commonly used to demonstrate best agronomic practices utilized
these new innovations in order to visually educate the farmer on best management practices. The
formation of these test plots is largely due to the work of Seaman Knapp. Dr. Knapp believed
that communities should develop demonstration farms under the guidance of the Department of
Agriculture (Bailey, 1945). A suitable amount of money must be raised in order to cover any
losses that may be sustained by the owner and operator of the farm while under the supervision
of the Department. This type of operation has evolved to present day test plots on governmental
lands as well as those of individual farmers. The psychological key to unlock the door to the
farmer’s cooperation was found when the farmer involved in the first test plot reported to have
made profits significant enough to encourage the demonstrated practices on his entire farm.
Seaman Knapp stated, “What a man hears he may doubt what he sees he may possibly doubt, but
what he does himself he cannot doubt” (Bailey, 1945, p. 155).
This type of demonstration was in need of expansion to other members of the community
than solely farmers. The corn club for boys and the canning club for girls were established. The
demonstration club for boys was an unavoidable decision from the beginning. Knapp realized
that younger men and boys adapted to new practices easier than did their elder counterparts. The
ability to encourage this younger population to become active members of the agriculture
industry was a positive one (Bailey, 1945). This involvement with cutting edge agriculture
technology had significant impact on the perceptions of these youth with regard to the industry.
These organizations have evolved over time to what we presently know as the 4-H organization.
Although projects that members of this organization work on have a similar foundation to
those demonstration projects of the first corn club members, the activities of the organization
have expanded and evolved over time. Nearing its 50th anniversary, 4-H began to undergo
several changes. In 1948, a group participated in the first International Farm Youth Exchange.
Since then, 4-H has begun to extend into urban areas in the 1950's. Later, the basic 4-H focus
became the personal growth of the member. Life skills development was built into 4-H projects,
activities and events to help youth become contributing, productive, self-directed members of
society. The organization changed in the 1960's, combining 4-H groups divided by gender or race
into a single integrated program. The current 4-H program consists of 6 million young people
and 60 million alumni. 4-H'ers participate in activities supported by the latest research of land-
grant universities. The program’s three areas of focus are: Science/ Engineering/
Technology, Healthy Living, and Citizenship. (National 4-H Council, 2009)
While the cooperative extension service has enhanced the production side of agriculture,
the need for a combined voice to support legislation, marketing, and policy existed. This need
was similar to the one on which the members of mechanized industries based their unions. These
unions already existed and were utilized as models for communication and structure. The need
for cooperation among farmers that was noted by county agents across the state of
Louisiana was brought to the forefront when the Louisiana State University College of
Agriculture invited representatives to visit with Louisiana Farmers in 1920. Over one hundred
farmers from across the state of Louisiana met with the Dean of the College of Agriculture at
Louisiana State University and established the Louisiana Farm Bureau.
Louisiana Farm Bureau
After World War I, the prices of agriculture commodities plummeted due to the fiscal
depression that the country was experiencing and the ongoing drought that plagued the mid-west.
The independent nature of the farmer who was adventuresome and opinionated was faced with
many issues that were new to them. It became evident that in order to approach the new
problems with any type of success, they must align themselves together as one group and one
voice. The need for social recognition provided a push toward organization. (Kile, 1948)
Many started to leave the farm for jobs in cities during the industrial revolution. They formed
union groups to mediate their stand on job conditions, living expenses, and other issues that
affected them. This type of organization was later mirrored in a somewhat different form by the
agriculture sector. This flight from the farm caused an influx of immigrants to the United States
after World War I. This influx was due to the lenient immigration policy that the U.S. held after
the war (Woell, 1990). This was influential on the American agricultural scene due to the
number of these immigrants that became members of the farming population.
These immigrants brought with them the idea that farmers were no more than peasants
who worked long strenuous hours for little pay. The reference to all farmers as “just farmers”
was demeaning and untrue. Many native farmers also felt that they were termed in this manner
as well. The American farmer had dared when others had wavered. They had cleared the forest
and seeded the fields, while lesser men sought sheltered occupations. (Colby, 1968)
Social issues were not the only problem facing agriculture. In the 1920s Louisiana cotton
was king. Sugarcane and rice were following the trend of wheat and corn in the Midwest where
farmers were struggling to make ends meet. Farming proved to be as volatile as any market.
Farmers were often not able to set the price that they would ask for their goods. The agriculture
market is the closest example of a competitive market currently known. Because of this
structure, the farmer felt economic fluctuations more than any other individual business and
made survival extremely volatile. (Kile, 1948)
The newly formed farm organizations were of four principal types. These organizations
had (1) a central membership with farmers spread across the country that paid a membership fee,
(2) central organizations of delegates from townships and other local units, (3) representation
from other various farmer groups, (4) a dissociated farmers club without scattered about through
which the county agent could do his work. The main purpose of these new farm organizations
was to gather together a group of interested people who could plan projects that could be used
for demonstration teaching. The need for promotion of other outside agriculture interests was
also aided by the formation of this group. (Kile, 1948)
The name of “Farm Bureau” was coined by Byers H. Gitchell, secretary of the
Binghamton, New York Chamber of Commerce. On a tour of the rural portion of the state of
New York, the state Secretary of Agriculture stated his concerns with the abandonment and
decline in the number of farming operations. Mr. Gitchell had already created several other
bureaus to address issues in transportation and manufacturing. The logical name for an
organization that addressed issues with relation to the farm was the “Farm Bureau”. Although
this name and its mental association with governmental bureaucracy has not been extremely
beneficial, the establishment of this organization by this name at the local and state levels left
little choice for change. (Kile, 1948)
The first national meeting to discuss the formation and incubation of a Farmer
Organization took place in Ithaca, New York. The idea of a Farm Bureau grew rapidly and the
first state meeting was held on November 19, 1919 in Chicago, Illinois. In little more than a year
the leaders in the farming industry were organized into a group of over one million members.
This group was actively marketing their crops as one, buying train loads or supplies and
equipment through cooperative memberships, and influenced state and local laws like never
before. This Agrarian Crusade, as termed by Solon J. Buck, was more powerful than anyone
could have predicted. (Kile, 1921)
James R. Howard stated in the Birmingham news that the real birthplace of Farm Bureau
was Louisiana. He stated that the inception of the Extension Service by Seaman Knapp also
started the organization of farmer groups that discussed policy, marketing, and other needs above
the production practices taught by the county agents. James Howard was one of the early leaders
in the Farm Bureau movement and became the first President of the American Farm Bureau
Federation. The tie between the Farm Bureau and the Extension Service was evermore present.
Farm Bureaus and Extension Services were used by President Herbert Hoover in order to
strengthen his election campaign due to the tremendous social and political forces that these two
groups held as a combined effort. (Robertson, 1983)
American Farm Bureau has enhanced and influenced many factors that have changed the
course of American agriculture. This organization currently follows the objective that the
organization is to “develop, strengthen, and correlate the work of the state Farm Bureau
Federations of the Nation; to encourage and promote cooperation of all representative
agricultural organizations in every effort to improve facilities and conditions for the economic
production, conservation, marketing, transportation, and distribution of farm products; to further
the study and enactment of constructive agricultural legislation; to advise with representatives of
the public agricultural institutions cooperating with farm bureaus in the determination of
nationwide policies, and to inform farm bureau members regarding all movements that affect
their interests.” (Kile, 1921) The Louisiana Farm Bureau follows all of the above objectives but
states that their own objectives are to unite the farmers in a constructive organization, to serve as
a clearinghouse of information, coordinate efforts and aims of various agricultural agencies, and
to serve as an overall agricultural organization that fights to overcome the common problems to
agriculture throughout the state (Kemmerly, 1941). There are several subdivisions under these
objectives that include (1) representation of the farmer and farmer interests, (2) educating the
urban sector on the relationship of the farmer to other units in the social and economic setting
and to establish agriculture as the foremost industry on which all others depend, (3) safeguarding
the rights and interests of the farmer when dealing with legislative policy and defending the
farmer with regard to these policy decisions, and (4) protecting and extending marketing or
crops, extending new foreign markets, and reducing cost of necessities to production. (Woell,
1990) Louisiana Farm Bureau currently continues to uphold these objectives. The divisions of
Public Relations, Marketing, Commodity Policy, and Membership Development still closely
relate to the original areas of concern.
Farm Bureau was originally founded as a federation of members made up by full time
farmers and ranchers. Although membership has now been extended to the general public with
the payment of annual dues, full time farmers are the only individuals who can hold leadership
positions within this organization. These farmers are representative of each area of the state and
all major commodities.
Historically the active members of this group have been row crop, field grain, livestock
farmers. Although recent years have included those involved in horticulture, wildlife, and
aquaculture, the backbone of the agricultural sector remains the row-crop, field grain, and
livestock farmers. The first commodity committees at the national level started in 1944. These
groups included fruits and vegetables, livestock, dairy, poultry, and field crops. (Kile, 1948)
Historically, the commodity groups that were taken into consideration with regard to
legislative policy and marketing in Louisiana have included producers of the commodities of
cotton, corn, rice, sugarcane, sweet potato, forestry, poultry, beef, and dairy. (Kemmerly, 1941)
Louisiana Farm Bureau continues to support each of these groups at present time.
The national legislation dealing with agriculture production and economics, titled the
Farm Bill, limits the commodities to include field grains, cotton, corn, soybeans, dairy, beef,
poultry, rice, sweet potato, and sugarcane/ sugar beets (United States Department of Agriculture,
2008). For the purposes of this study we will include those fields of agriculture that involve the
production of the above mentioned commodities. We will continue to exclude the production of
the commodity forestry as well as any other portions of such industry due to the difference in
nature of production, manufacturing, the maturation time of this crop, and most importantly the
exclusion of this commodity from the Farm Bill. The inclusion of each of these areas as
mentioned above will be assumed when we describe agriculture as a whole.
Agricultural Literacy
Literacy is a phrase that has been utilized in combination with knowledge in many educational
situations. Literacy can be defined as a base level of skill or knowledge that one possesses that
allows them to competently complete a task (Sticht, 1975). This can also be the ability to
competently respond to information and make educated decisions. Just as the definition can take
on many uses, the level of knowledge needed to reach a certain skill level is measurable in one
instance but not necessarily generalizable to other situations. The level needed is relative and
without absolute standards. (Frick, Birkenholz, Gardner, and Machtmes, 1995c) The knowledge
needed to be literate on a given subject is only a minimum level and not to be misunderstood as a
complete understanding of the subject.
Knowledge with regard to agricultural information is commonly referred to as
agricultural literacy. Agricultural literacy is a concept that is founded on the idea that all
individuals should possess a basic level of understanding of the agriculture industry. It has been
stated recently that the broad range of American citizens are in general “agriculturally ignorant”
(Coon and Cantrell, 1985). Causes for the low level of agricultural literacy are broad in range.
The urbanization of the American population, the concern of social issues that involve
agriculture and misinformation about agricultural topics are all thought to be causes.
The first step in assessing agricultural literacy is to determine the current level. A
benchmark that verifies the level of agricultural knowledge and perception of agriculture should
be determined.
The second step is to address important areas of agricultural literacy. Frick (1990)
utilized seven concept areas in his benchmark Delphi study that include (1) global significance of
agriculture, (2) public policy, (3) relationship with the environment and natural resources, (4)
plant sciences, (5) animal science, (6) processed agriculture products, and (7) marketing and
distribution of agriculture products.
If agricultural literacy is to improve agricultural knowledge then perception of agriculture
should be assessed as effects to agricultural literacy in many differing situations with each of
these seven areas included. The Agriculture Council of America reemphasizes this by stating
that increased knowledge of agriculture allows individuals to make informed personal choices
(Agriculture Council of America, 2008).
Braverman, et al. (1991) noted that agricultural literacy is a major concern for adults in
our society. He stated that with increasing frequency and urgency, adults in American society are
called upon to make decisions about critical agriculture-related issues such as food safety, land
use, and water policy. In order to make informed decisions, the American public must have a
basic understanding of agriculture and its role in our society and economy. Braverman and Rilla
(1991) go on to say "Society often fails to recognize that agriculture encompasses the study of
economics, technology, politics, sociology, international relations and trade, and environmental
problems, in addition to biology" (Braverman and Rilla, 1991, p.4)
A study supported by grants from the W. K. Kellogg Foundation was established to
evaluate the effects that inclusion of agriculture in liberal arts college curricula had on
knowledge of agriculture issues in the context of society’s broad goals. The importance of
agriculture with regard to issues such as world hunger, international development, environmental
issues, and political actions were examples of the items incorporated into curricula. Ten liberal
arts colleges participated in this study and explored agricultural linkages to the liberal arts in a
combination of multiple interdisciplinary forms. This exploration included agriculture in the
curriculum, in public events held by the university, through field experiences, and library
resources. The study found that the importance of how knowledge is acquired was more
important in the educational process than deemed before. The inclusion of observation and
practical work experience complements and reinforces students’ studies. (Douglass, 1985)
Many states have expressed concern involving agricultural literacy. The California
Department of Education (2009) stated that the lack of knowledge and influence forces seriously
challenge American agriculture and education. These forces include changing demographics,
urbanization, and lifestyle changes; rapid increases in world-wide agricultural production needs;
domestic farm and trade policies; and global competition in high technology industries. The
application of knowledge available through use of sophisticated computers and technology such
as digital equipment, and biotechnological techniques can be modified by the agricultural
awareness of the general public. A statewide comprehensive program of agricultural literacy and
awareness provides infusion of agricultural topics and information into a broad range of
academic subject areas. Agricultural literacy and awareness supports a strong career preparation
program that not only meets the needs of a dynamic and competitive agricultural industry in
California, but also prepares a citizenry attuned to the health and economic importance of a very
productive industry (California Department of Education, 2009).
Arizona Cooperative Extension (2009) has also expressed support of agricultural literacy
programs. Their mission is to assist educators in the effective use of incorporating information
about agriculture into the subjects they already teach while educating consumers about the
agriculture industry in Arizona and its impact on the general public. A similar study by Pense
and Leising (2004) sought to assess the agricultural literacy of high school seniors in Oklahoma.
The study findings reported the participants to have low overall agricultural knowledge scores of
students. It was determined that the program completers who participated in the study were not
agriculturally literate. Boatner found similar results when agricultural literacy was measured in
Willamette Valley’s forth grade students. This study found the average score was found to be
6.12 questions correct out of 12 questions, or a 51% correct. The high scoring student answered
ten questions right and the lowest score was two questions.
Programs such as the Agriculture in the Classroom program have been implemented in
several states as a means to provide agriculture education to all school age children. A study by
Pense, Leising, Portillo, and Igo, (2005) sought to assess change in student agricultural
knowledge after implementing Agriculture in the Classroom (AITC) programs and to identify
strengths and weaknesses of student knowledge according to the five thematic areas. The study
included selected classrooms of kindergarten through sixth grade students that had AITC trained
teachers. These classes were in the states of Arizona, Montana, Oklahoma and Utah. Pre-test and
posttest mean score comparisons by grade groupings were made and in the five thematic areas.
The results reported greater agricultural knowledge in all four grade groupings with AITC
trained teachers. The study concluded that AITC training of teachers made a positive difference
in student acquisition of knowledge about agriculture.
Pals and Waitley (1996) developed a project to help the elementary school students in
Idaho learn more about agriculture. The project also helped in preparing a presentation and
developing writing skills. The curriculum was taken from the Idaho Agriculture in the Classroom
(AITC) which was created to focus on fourth grade students. The elementary school students
prepared presentations to present to fourth graders, which included hands-on, fun activities. The
project revealed that there are not enough instructors to teach the importance of agricultural
literacy to middle school students.
Other programs that produce agriculture materials include the Agriculture in Montana
School Program. Moore and Violett (1996) studied middle school agricultural education in the
state of Montana. For their study, they used the curriculum for eight Montana Schools which is
provided by Agriculture in Montana Schools. Moore and Violett discovered that there was a
tremendous amount of agricultural literacy material available to the middle school teachers, but
the problem seemed to be what part of agriculture to teach the students. The two schools used in
this study were from southeastern Montana, but had different student populations. One school
was in an isolated part of the state where agriculture is the main source of the economy. The
school enrolled 77 students from grades 7-12. The larger of the schools had 700 students from
grades 6-12 and was located in a suburb. The students were taught the importance of
agricultural literacy through game-type activities, so it would be fun and interesting for the
middle school students.
Studies that measure agricultural literacy in selected areas of agriculture have been
conducted. A study by Harbstreit and Welton (1992) measured high school agriculture students’
awareness about international agriculture in the areas of agricultural products, agricultural policy,
geography, and people and cultures. The study found that awareness is limited. The study also
found that agriculture students with higher grades possess more knowledge about international
agriculture than their counterparts with lower self-reported grades, student awareness about
international agriculture increases as advancement is made to the next high school class, and the
longer a student is a part of a high school agriculture program and involved with supervised
occupational experience, awareness about international agriculture increases.
Knowledge
Knowledge can be defined as the understanding of information and the ability to apply
and utilize this information in independent situations. Knowledge is what is known. There is not
a single definition of the term knowledge on which scholars agree, but rather numerous theories
and continued debate about the nature of knowledge.
Knowledge is part of the hierarchy made up of data, information, and knowledge. Data
are raw facts. Information is data with context and perspective. Knowledge is information with
guidance for action based on insight and experience or the result of applying data processing to
data, giving it context and meaning to yield knowledge. What is known by perceptual
experience and reasoning. For example, 1234567.89 is data; "Your bank balance has jumped
8087% to $1234567.89" is information; "No one owes me that much money" is knowledge; and
"I need to talk to the bank before I spend it” is the utilization of the knowledge gained.
Knowledge has been referred to as cognition, or the psychological result of perception and
learning and reasoning (Information, (data) information section, para. 1, n.d.).
Shapiro (2004) states that knowledge has a marked effect on learning outcomes.
Researchers try to control for that factor in learning research but are not always successful. This
study demonstrated that experimental controls are not successful in controlling knowledge
effects. The study included students who read texts about fictional places and events and
students who were asked to read several advanced texts. In both experiments, prior knowledge
accounted for a large portion of the subjects' test performance. It can be reasoned from this study
that knowledge could influence perception and the outcomes of perception.
If the reverse is true and knowledge is a resulting effect of perception or education then
the ability to adjust or sway perceptions may adjust the knowledge or assessments that
individuals may have with regard to the agriculture industry. With this relationship in mind, one
can see how the study of perception and knowledge should be done in conjunction with each
other in order to combine the effects of both as a whole.
Perception
Although it is difficult to explain how items, events, and individuals in the world can be
recreated in a mental form in our minds, the field of Psychophysics has evolved to study this
phenomenon. This field of study attempts to relate the physical properties of someone or
something to the reaction that we have with regard to these properties. This reaction is the direct
result of our perception of the situation. Both positive and negative perceptions are based on
one’s own experiences (Raab and Grobe, 2005).
Matlin defines perception as the study of the way you gather and interpret information
about the world around you. “Everything you know about the world in based on perceptual
information” (Matlin, 1983, p. 2). James J. Gibson (1950) suggested that in order to explain
perception we should explore the objects that we see, the sounds that we hear, and the feel of
objects in order to see which features cause the reactions and inevitably the perceptions that we
calculate with regard to these occurrences. The same principles can be used for the calculation
of responses to exposure to information and experiences. The awareness, recognition, or
experiences with a given subject are all elements that are used
Mowan (1995) develops the idea of perception utilizing stages which include exposure,
attention to information, and comprehension. These stages are also reflected in Matlin and
Foley’s (1992) three stages of sensation, perception, and cognition. The exposure or sensation
portion of this process is the stage in which individuals receive information from senses or
experiences. The attention or perception stage is the portion of the development that allows an
individual to process the individual sensing aspects of an encounter and mentally record these
factors. The comprehension or cognition stage includes the interpretation of the encounter or
event and drawing conclusions, making suggestions, or calculating the risks and benefits
associated with a given choice. Mowan (1995) also states that it can not be assumed that each
person will react in exactly the same manner to a stimulus or perceive it in the same manner due
to the influence of expectation, background, present knowledge, and historical occurrences.
Each of these alone or combined can cause varying degrees of reaction shifts. (Mowan,
1995) For example, farmers have been found to have a more positive attitude toward pesticides
due to their knowledge about the topic and their personal calculations of risk and benefits,
(Whitford, 1993) while the non-agriculture population is more apt to have a negative perception
due to their lack of knowledge about risk and potential value (Raab and Grobe, 2005). The same
type of reaction can be seen more recently in the purchasing choice of consumers with regard to
organic foods. Up to twenty-nine percent of Americans surveyed believe that the USDA
standards placed on organically grown foods in 2002 and the media associated with these
standards increased their knowledge in the area of organics and positively influenced their
decision to purchase these types of products. (Raab and Grobe, 2005) In order to understand
these cognitive shifts we must also understand the theory and causes behind these choices.
Discrimination and criterion are important factors in explaining perception. Criterion is a
term used to describe the ability of one to sense the situation and value the payoff or rewards
associated with a given response. Discrimination is the ability to determine the extent to which
the given situation will change. The determination as to which choice will change less or which
one will have the greatest payoff or reward is calculated. This determination of the balance
between benefit and risk is often viewed as separate calculation that must result in a conclusion
based on one outcome or the other. Whitford views the system as one calculated measure and
states that it should be viewed with the inclusion of benefits and risks as overlapping factors in
the decision making process. This coevaluation allows a truer analysis of the criterion to be
calculated. (Whitford, 1993)
Several terms have been utilized to describe the sensation of perception. These terms
have included “Awareness” (Wright, Stewart, & Birkenholz, 1994), “Attitude” or “Attitude
Formation” (Wiley, Bowen, Bowen, & Heinsohn, 1997), “Expected Impact” (Williams, 2000), or
“Opinion” (Nedley, 2006). Regardless of the phrase that is used, these are each examples of
perception theory that has similar research back grounding.
Knowledge and Perception of Agriculture Studies
Due to the impact that agriculture has on our society, economy, environment, and
personal health, it is vital that the general public be knowledgeable and has accurate perceptions
about agriculture. (Terry and Lawver, 1995) The need for a true understanding of agricultural
related issues will continue to increase as future generations take leadership roles and make
public policy decisions with regard to the agriculture industry. Brannon, Holley, & Key (1989)
measured the effect of the FFA program on people involved in community leadership. They
surveyed thirty communities in Oklahoma that had agriculture education programs in the local
school and found vocational agriculture/FFA as a contributing factor to community leader
success. The study revealed a mean rating of 3.98 out of 5.0 with 63 (17%) leaders indicating
that it had a great impact and 58 (16%) indicating that it had much impact. Community leaders
surveyed who had participated in vocational agriculture felt that their leadership activities were
effective in developing their leadership skills, contributed much to their success, and have been
of value in their careers regardless of occupation.
The need to address the problem of agricultural literacy, lack of agricultural knowledge,
and negative perceptions has become increasingly important as the general population becoming
more illiterate with passing generations (Frick, et al., 1995c). Frick, et. al. (1995c) reported that
the knowledge and perceptions of agriculture and related issues measured in rural high school
students were higher than those of urban students. The difference in these two groups is their
exposure to the subject matter which reemphasizes the relationship between agricultural literacy,
agricultural knowledge, and perception. In a similar study (Frick, et al., 1995b) that addressed
knowledge level of agriculture of rural and urban adults, it was found that twenty-nine and
onehalf percent of the respondents provided answers that were incorrect or answered that they
did not know the correct answer. Those that reported their residence to be rural held higher
knowledge levels of agriculture than their counterparts who reported their residence to be in an
urban area. Although both studies showed that both groups had some agricultural knowledge,
rural residents had higher knowledge levels. The low overall mean scores of agricultural
knowledge and perceptions of agriculture suggested that there is ample room for increased
education to raise agricultural knowledge levels.
The location of residence proved to be an important variable in two other studies
conducted. The first of these studies was conducted by Wachenheim and Rathge (2002) and
surveyed residents of the North Central region of the country. This study concluded that an
individual’s experience with and proximity to agriculture influences their perceptions. Frick, et
al. (1995a) also concluded that of the 4-H members surveyed, those who lived on a farm or in a
rural setting held higher knowledge and perception levels than those who did not possess this
trait. In a study of three high schools in the state of New York (Smith, Park, & Sutton, 2007), a
statistically significant difference was found between rural high school students and urban high
school students. The rural students held higher levels of agricultural literacy and their
knowledge and perception scores were in line with the actual state statistics.
Krueger and Riesenberg (1991) noted that the decline in enrollment in agricultural
programs in recent years is due to the misconceptions that students and the public have with
regard to the agriculture industry and agriculture careers. Perritt and Morton (1990) state that
most children in urban areas receive very little exposure to production agriculture. Unless the
current perceptions are understood, the errors in misinformation and lack of agricultural
knowledge can not be corrected (Newsom-Stewart and Sutphin, 1994). High school students in
California are unaware of the range of opportunities in agriculture. While high school juniors
and seniors list a stable and secure future as a top priority in choosing a career, they view
agriculture as outdoor, hard work, blue-collar, and insecure. They rated agriculture as lowest on
the qualities of providing a stable and secure future or earning a lot of money (Mallory and
Sommer, 2001).
A study conducted by Osborne and Dyer (2000) sought to describe the attitudes of
students and parents toward the agricultural industry and careers in agriculture. Although both
students enrolled in agriculture courses and their parents held more positive attitudes toward the
agriculture industry than those students who had no enrollment in agriculture courses, their
perceptions of agricultural careers varied. This variance was due to the amount of science
application included in the agriculture instruction that was administered. Those students and
parents who had more science application in their agricultural curricula had more positive
attitudes than those who did not have this application of science. A similar study by Dyer, Lacey,
and Osborne (1996) sought to understand enrollment trends in agriculture majors. The study
surveyed university freshmen enrolled in agriculture programs and found that the majority were
female, Caucasian, and held no agriculture background. The majority of the respondents found
high school agriculture to be good preparation for college and viewed agriculture as being both
scientific and technical.
These misconceptions with regard to the agriculture industry and agricultural careers are
extremely prevalent in minority populations. Given that the consumption of food is the primary
contact that many minorities have with agricultural sciences (Wiley et. al, 1997), many
minorities exhibit limited awareness of the science and business skills that are utilized in this
industry. The lack of knowledge that results in low perception of agriculture affects recruitment
into agriculture or related education and employment fields. The resulting small numbers of
individuals involved in the agriculture industry are maintained by ongoing perceptions that
agriculture is an industry focused on vocational skills and one meant for white males. (Wiley, et.
al., 1997) Findings from Beck and Swanson (2003) show Black and Hispanic graduate at levels
less than three percent for all degree levels in agriculture fields. The barriers that limit minority
enrollment were studied (Dobbins, King, Fravel, Keels, & Covington, 2002) and the major
reasons were reported to be hard jobs, long hours, low pay, and outdoors or just farming. Similar
findings by Krueger and Riesenberg (2001) found that students perceived an agricultural career
to be boring, hard work with poor pay, and involving more muscle than brain. Another study
(Esters and Bowen, 2004) found that the mother or female guardian has the most influence over
the choices and decisions that students make.
In similar studies it is reported that Black and Hispanic students are more likely to have a
negative perception of agriculture than students in other ethnic groups (Nichols and Nelson,
1993), which could relate to decreases in minority enrollment. Newsom-Stewart and Sutphin
(1994) found significant differences between the perception means. Means for white students
were higher than other ethnic groups for most items in the survey. This was also made obvious
by the limited appeal of agriculture to Asian students as a place for high school or college
graduates to work. Cultural differences in experience and differential socialization processes may
lead to the observed ethnicity differences in perception. Results suggest that educational
interventions are needed to encourage minority groups to better understand agriculture and
develop a more positive view of agriculture careers.
These misconceptions are not limited to minority groups. A focus group study of rural
and urban youth found that the participants equated agriculture with farming, but made no
connection to the technical or research-intensive aspects of agriculture. For example, farming
was perceived to be hard, physical labor and stressful because of machinery breakage, weather
uncertainties, and price variances. Youth, both rural and urban, tended to think of farmers as
wearing bib overalls and chewing on a straw. Most youth were generally aware of the
importance of agriculture to food production. The participants acknowledged that without
agriculture there would be no food. If agriculture disappeared, their personal lives, as well as
their community and state, would be affected. (Holz-Clause and Jost, 1995)
Understanding the relationship between knowledge and perceptions of agriculture, it can
be reasoned that education that increases knowledge of agriculture would have a positive impact
on perception as well. In all studies that measured knowledge and perception it was found that
those with higher agriculture education levels tended to possess higher scores in both areas.
Agriculture education has been the backbone of 4-H, FFA/ Ag Education classes. These and
other youth organizations tied closely to agriculture education have produced individuals with
extremely high levels of knowledge and perception with regard to the agriculture industry.
(Frick, et al., 1995c) Townsend (1990) believed that a pre-secondary agricultural education
program can build a positive attitude among students that will let them develop into positive
leaders. Riedel (2006) reported findings that supported this belief. The Riedel study found that
introductory courses in agriculture had a significant impact on agricultural knowledge. The
pretest score of overall agricultural knowledge and agricultural literacy was 20.99 or a
percentage score of 60%. The respondents’ final overall knowledge mean score was 24.13 on a
35-question literacy instrument or a percentage score of 69%. There was a nine percent increase
in overall literacy scores upon completion of the introductory agriculture course.
An increase in agriculture education directed toward groups that have no experiences in
agriculture programs should be implemented. These individuals have lower agricultural literacy
levels, more distance between themselves and rural areas, and lower educational levels.
Allowing this group the same information as those involved or surrounded by agriculture would
increase the average knowledge and perception of the general public. Dyer, Breja, and
Andreasen (1999) found that most college freshmen majoring in agriculture were white males
and had an agriculture background. He reported that the greatest influence on their decision to
major in agriculture was their high school agriculture teacher.
Studies in Kansas (Horn and Vining, 1986) and Virginia (Oliver, 1986) indicated a lack of
basic knowledge about agriculture among all elementary school students. Brown and Stewart
(1993) studied middle school students’ knowledge and attitudes before and after being exposed
to an agriculture curriculum. The results of this study indicated that there can be an improvement
in the agricultural attitude of middle school students in selected Missouri schools through
instruction about agriculture. This age group of students represents an important educational
stage for developing an increased understanding and appreciation about agriculture. This study
found that exposure to an agricultural education curriculum for a period as short as six weeks can
have an impact on middle school students’ agricultural knowledge. Although formal agriculture
education is referenced in several studies before mentioned, it is worth noting that Herren and
Oakley (1995) found that the influences that teachers with agriculture backgrounds have on
children can result in higher scores on agricultural knowledge tests than those children whose
teachers had no agriculture background. These results were based on the results of a survey
administered in sixteen classes of second grade children and twelve classes of fourth grade
students. Trexler and Meischen found that although teachers from rural areas demonstrated more
understanding of agriculture technology, overall the teachers did not possess requisite
understandings to help elementary students gain knowledge and understandings of, or concern
for the trade-offs found in the use of agricultural biotechnologies. A similar study (Trexler and
Suvedi, 1998) measured the impact of an e-program to increase science and agricultural literacy
in Sanilac County, Michigan. This study found that although principals were very positive about
teaching science through agricultural examples, the teachers held lower perceptions. Three years
later the perceptions of the teachers were high along with their comfort level of teaching science
through agriculture examples. This reinforces the need for agriculture education of all types for
school age children. Non-traditional programs should be developed at the elementary school
level to educate students about food, agriculture, and renewable resources (Trexler and Suvedi,
1998).
Measurement of the general public are needed to steer educational materials and public
relations activities. Bell (1995) studied the knowledge and awareness of members of civic
organizations with regard to agriculture. As an overall group, members of civic groups are not
very knowledgeable about general agriculture. This is based on the finding that their mean score
was 4.1 out of 15. Members of civic groups are much more aware about agriculture than they
are knowledgeable about it The mean score of 28.7 out of 35 possible in the general agricultural
awareness section points to a population which equals 65% of the respondents being somewhat
aware of the importance of agriculture and its activities. However, it should be noted that civic
groups, as a whole, are still unaware of many important agricultural activities. In a similar study
by Willits, Luloff, and James (2006) residents of Pennsylvania were studied to measure their
perceptions of agriculture. The survey showed that direct personal contact with farming and
visiting rural areas were the most important experiences associated with higher levels of
agricultural knowledge. The findings also showed that people who have greater agricultural
knowledge differ in their views and actions from those with less understanding of agriculture.
Lockaby and Ryan (1994) conducted a study that surveyed leaders in a Texas city where
agriculture has a great economic impact. The survey consisted of seventy items. Sixty items were
agricultural literacy questions which included agricultural knowledge, total awareness, and
awareness of High Plains and South Plains agriculture. The study found that city and government
leaders were not knowledgeable about agriculture in general. Those leaders who raised animals
or crops and/or took agricultural classes in high school had greater agricultural knowledge than
those who did not. Even though city and government leaders were not knowledgeable about
agriculture, they were aware of the problems that face agriculture.
A perception study conducted by the University of Florida comprising a statewide survey
of more than 300 registered voters in Florida about food and agricultural issues revealed that
more than 82% of those surveyed were confident that farming is safe for the environment, with
only 11% citing a lack of confidence, 80% of the respondents had favorable opinions of Florida
agriculture, and 98% of the people surveyed believed agriculture is important to Florida’s
economy. (Nedley, 2006) A similar result was found by Terry and Lawyer (1995) when they
surveyed university students on their perceptions of agriculture. They found that the overall
student perceptions about food safety and the impact of agriculture upon the economy and
environment were favorable. Gender and college major were both variables that impacted
perceptions. Males tended to have more positive perceptions as well as those with an
agricultural major.
Additional studies have found that the public’s overall knowledge and perceptions of the
topic of the environment and sustainable agriculture tend to be higher than those of other
agriculture topics. Williams (2000) found that perception of sustainable agriculture and the
expected positive impact that this practice has on the environment were of concern. Although
the group of agriculture education students held low knowledge levels of sustainable agriculture,
their perceptions of this practice were high. Similar results were found (Williams and Wise,
1997) when sixty teachers and their agriculture education classes were surveyed. This group
reported that they held high perceptions of sustainable agriculture and the environment. Terry
and Lawver (1995) found university students to have favorable perceptions about agriculture and
its impact on the environment. The Agriculture Institute of Florida (Nedley, 2006) reported that
eighty two percent of the respondents to an agriculture opinion survey were confident that
farming is safe for the environment. Wachenheim and Rathge (2002) reported a similar finding
for members of the north central region of the United States stated that they viewed farmers as
good environmental stewards and that current existing environmental regulations are appropriate.
Using Public Perception for Decision Making
The idea that personal experiences, observations, influences, knowledge, and values
about agriculture influence beliefs, intentions, and decisions has been studied over the past thirty
years (Fishbein and Ajzen, 1975). Although decisions can also be influenced by other notable
individuals within one’s life, it can be stated that knowledge can affect perception and attitudes
which can in turn affects decisions that are made.
Swanson (1972) developed a theory of assumed relationships among education,
knowledge, attitudes, and behavior. This theory is predicated on reasoning that that knowledge
and experiences, including education and first hand experiences, are precursors to attitudes and
behaviors. Swanson also suggests that the initial temporary perceptions often become more
permanent knowledge, leading to a change in attitude, which can govern ones behavior and
actions. An attitude may be such that it is not able to be put into words in order for it to be
expressed toward an issue or question, yet it may still affect behavior and actions. Fishbein
(1967) theorized that attitudes help individuals adjust to their environment providing
predictability in their behavior and aid in the understanding of others’ behavior.
A detailed description of the decision making process which included the science and
systematic approaches to making these assessments was referred to as the Analytic-Deliberative
Process by Stern and Fineberg (1996) in works titled Understanding Risk. This process takes
into account the affected parties, dialog, participation, and deliberation into every element of risk
analysis. Perceptual information gathered from individuals can be categorized into three main
classes: (1) deliberative methods which include conferences, juries, small planning groups, etc.,
(2) consultation methods that include group input from meetings, surveys, and focus groups, or
(3) referenda in which all people involved have a democratic vote. The utilization of all, or
combinations of the above mentioned three tools to gather information, increase the validity of
the information gathered.
A notable study reflected on the ability to make a decision that involved a surmountable
percentage of risk utilizing only the perception of individuals. The decision at hand dealt with
the commercialization of biotechnology. The question was whether open deliberation, focus
groups, and an interactive debate website would provide a simulative sample response similar to
that received by the traditional statistically representative survey. The answer to this question is
not due to the significant difference found between the two groups of responses. The plausible
explanation for the differences is that the open-debate activities primarily attracted extreme
members of the subject opinion group and the focus groups were not selected as a true
representation of the population to which this study is generalizable. It can be concluded by this
outcome that the manner in which data is collected may have great impact on the ability to utilize
true perception in a responsible way. (Pidgeon, Poortinga, Rowe, Jones, Walls, and O’Riordan,
2005)
When Americans express their opinion about animal cloning (Hallman and Condry,
2006), they are more likely to reflect their impressions of the topic rather than that indicative of a
portion developed over time that has been deliberated and supported by a foundation of factual
information. The effect of media coverage, public opinion of others, and lack of knowledge are
all effects that steer these perceptions. The same type of perception effect can be seen in other
areas of animal biotechnology. The general public has deemed recent production animal
agriculture as being controlled by corporate interests and motivated by profits rather than animal
care values (Fraser, 2001). Although agricultural organizations have rebuked these allegations,
the public is faced with two contradictory images. The public needs knowledge based research
and analysis to serve as their foundation for public policy and choice. Perceptions on such topics
could have public effects if the ability to continue this type of research is banned or altered by
legislative process, indirectly set into motion by the general public.
Perception has affected decisions within the agricultural industry for decades. Every four
years a group of representatives gather in Washington D.C. and make decisions about our
economic and social wellbeing with little personal knowledge or expertise about the topics at
hand. Hamlin (1962) noted that farm policy, i.e. the farm bill, is created, debated, and put into
action by a group of individuals that hold little expertise in the area of agriculture. The decisions
that are made could be the difference between the success and the demise of the agriculture
industry in the United States. Public policy is a result of ill advised representatives that are
steered by public goals and the perceptions that are many times joined with silent social or
political issues. The dangers that exist when dealing with this type of one way transfer of
information and the unknown underlying issues are constantly being studied and are growing
increasingly important in a time when communication and information are easily dispensable.
These decisions are often made without regard to economic stability or security and how these
decisions will affect the general American public. Lack of knowledge about agriculture translates
to a poorly informed public majority having input in policy decisions "that may affect the
agricultural industry's ability to function efficiently in an increasingly competitive world market"
(National Academy of Science, 1988).
The low level of individual knowledge with regard to the global agriculture industry was
noted by Harbstreit and Welton (1992). The effects of history and maturation may have assisted
the conclusion that involvement in agriculture programs and occupational experiences may have
increased the agricultural knowledge of individuals. The longer students were exposed to
international agriculture the higher their ratings on knowledge were. Regardless of the effect of
the education on knowledge levels, the preliminary knowledge of international agriculture was
found to be at a scored level of thirty-six percent which is well below the average that one should
have when making decisions or influencing choices on a given topic.
Public perception does not only affect production agriculture. Pesticide use, food safety,
and genetically modified food and fiber sources are all examples of issues with varying
perceptions of their effects. Research has shown that perception with regard to these issues, and
many others, can differ among individuals. The difference in public perception and research
outcomes becomes a conflict that fails to communicate the scientific facts. The public opinion
based on these false perceptions will not be easily changed. (Slovic, 1992)
Although agricultural literacy has become a growing concern, it should be classified as
more of a threat. Literacy on any subject lies at the root of people’s attitudes and their actions
(Barton, 2000). The inability to make informed and educated decisions based on factual and
proven information not only affects one aspect of life but can grow to the range of having a
detrimental effect on economics, society, and global relationships.
Summary
Agriculture can be defined as the cultivation or tillage of the soil in order to produce food
or fiber for human use. (Merriam-Webster, 1996) Although the “tillage of the soil” has been in
existence for thousands of years, agriculture has become ever more important in recent years.
Agriculture has evolved over time from a large percentage of American colonists who were
farmers by trade that marketed and traded excess food and fiber to others in order to meet the
demands of those who held other occupations. Current farmers utilize innovations was such as
hybrid seed for crops, chemical fertilizers, and pesticides, all of which are commonly used today.
The adaptation of mechanical tools for the planting and harvesting of crops was also a major
evolution.
Many agriculture organizations have been established. Founded in 1928, the
Future Farmers of America (FFA) realized a need for bonding between agriculture students to
allow them to share common ideas, new technologies, and interests. Today it strives to ensure
that all students reap the benefits of agricultural education. (National FFA Organization, 2009)
The Farm Bureau held its first state meeting was held on November 19, 1919 in Chicago,
Illinois. Since that first meeting has enhanced and influenced many factors that have changed
the course of American agriculture with marketing and legislative actions (Kile, 1948).
The Hatch Act of 1887 established a cooperative bond between United States Department
of Agriculture and the nation's existing land grant colleges allocating annual federal funding for
dissemination of research to the general public. Congress also passed the Smith Lever Act in
1914. This legislation provided for the establishment of what is now titled the Cooperative
Extension Service which serves to “extend" information developed on teaching campuses and
research stations across the nation. Since its inception originating with the Hatch Act of 1887,
the Cooperative Extension Service has worked with the farmers and ranchers of Louisiana to
create the finest food and fiber production systems in the world (Encyclopedia Britannica, 2009).
The realized that younger men and boys adapted to new practices easier than did their elder
counterparts led to the formation of the Corn Clubs. This involvement with cutting edge
agriculture technology had significant impact on the perceptions of these youth with regard to
the industry. These organizations have evolved over time to what we presently know as the 4-H
organization (Kile, 1921).
The idea of perception utilizing three stages which including exposure, attention to
information, and comprehension. The exposure or sensation portion of this process is the stage
in which individuals receive information from senses or experiences. The attention or perception
stage is the portion of the development that allows an individual to process the individual sensing
aspects of an encounter and mentally record these factors. The comprehension or cognition stage
includes the interpretation of the encounter or event and drawing conclusions, making
suggestions, or calculating the risks and benefits associated with a given choice (Mowan, 1995).
Knowledge can be defined as the understanding of information and the ability to apply
and utilize this information in independent situations. Knowledge is what is known. Knowledge
is part of the hierarchy made up of data, information, and knowledge. Data are raw facts.
Information is data with context and perspective. Knowledge is information with guidance for
action based on insight and experience. If the reverse is true and knowledge is a resulting effect
of perception or education then the ability to adjust or sway perceptions may adjust the
knowledge or assessments that individuals may have with regard to the agriculture industry.
With this relationship in mind, one can see how the study of perception and knowledge should be
done in conjunction with each other in order to combine the effects of both as a whole.
Literacy is a phrase that has been utilized in combination with knowledge in many
educational situations. Literacy can be defined as a base level of skill or knowledge that one
possesses that allows them to competently complete a task (Sticht, 1975). This can also be the
ability to competently respond to information and make educated decisions. If agricultural
literacy is to improve agricultural knowledge then perception of agriculture should be assessed as
effects to agricultural literacy in many differing situations with each of these seven areas
included. Braverman, et al. (1991) noted that adults in American society are called upon to make
decisions about critical agriculture-related issues such as food safety, land use, and water policy.
In order to make informed decisions, the American public must have a basic understanding of
agriculture and its role in our society and economy. California, Arizona, Montana, Utah, and
Oklahoma are only a few of the states that have noted efforts toward Agricultural Literacy.
The need to address the problem of agricultural literacy, lack of agricultural knowledge,
and negative perceptions has become increasingly important as the general population becoming
more illiterate with passing generations (Frick, et al., 1995c). The idea that personal experiences,
observations, influences, knowledge, and values about agriculture influence beliefs, intentions,
and decisions has been studied over the past thirty years (Fishbein and Ajzen, 1975). Although
decisions can also be influenced by other notable individuals within one’s life, it can be stated
that knowledge can affect perception and attitudes which can in turn affects decisions that are
made. Swanson (1972) developed a theory of assumed relationships among education,
knowledge, attitudes, and behavior. This theory is predicated on reasoning that that knowledge
and experiences, including education and first hand experiences, are precursors to attitudes and
behaviors. Swanson also suggests that the initial temporary perceptions often become more
permanent knowledge, leading to a change in attitude, which can govern ones behavior and
actions. An attitude may be such that it is not able to be put into words in order for it to be
expressed toward an issue or question, yet it may still affect behavior and actions.
Perception has affected decisions within the agricultural industry for decades. Every four
years a group of representatives gather in Washington D.C. and make decisions about our
economic and social wellbeing with little personal knowledge or expertise about the topics at
hand. Hamlin (1962) noted that farm policy, i.e. the farm bill, is created, debated, and put into
action by a group of individuals that hold little expertise in the area of agriculture. The decisions
that are made could be the difference between the success and the demise of the agriculture
industry in the United States. Although agricultural literacy has become a growing concern, it
should be classified as more of a threat. The inability to make informed and educated decisions
based on factual and proven information not only affects one aspect of life but can grow to the
range of having a detrimental effect on economics, society, and global relationships. (Barton,
1990)
CHAPTER 3
METHODOLOGY
Population and Sample
The target population for this study was defined as adult residents of the state of
Louisiana. The adult residents of Louisiana can be defined as all adult individuals, of the age of
eighteen or older, living or residing within the legal boundaries of the state. All adult individuals
that were residents of the state of Louisiana were included in the target population of this study.
While legal residency requires having a permanent residence, registered to vote, and payment of
taxes in the state of Louisiana, these lists are not always able to be utilized for the purposes of
phone surveys. For the purpose of this study residency was derived by the individual’s
registration of telephone service in their name at a residence in the state of Louisiana.
The accessible population was defined as the group of adult individuals in the defined
target population who had registered residential telephone numbers. The survey frame of the
accessible population was established by the current residential phone listings registered in the
state phone company databases. These listings were a combination of all residential listings by
telephone companies servicing any area in Louisiana. All multiple listings at a single residence
were deleted. Those types of duplicate numbers include children’s phone listings, fax line
listing, and multiple numbers listed for a single address. No random digit dialing techniques
were used that may allow for numbers associated with cellular telephones, businesses, or
educational institutions (Dillman, 1978). The use of cellular telephones as main lines of
communication for households may be a source of population bias. The bias against this group
of society may be due to the choice to have one phone number due to financial restrictions. This
is a limiting factor of telephone survey in this survey.
The sample was derived by randomly selecting residential telephone numbers from those
listed in public directories. The random selection of numbers was done by a computer aided
selection process that randomly chooses a number from the finalized residential telephone
listing. The minimum required sample size for this study was determined to be 384 using
Cochran’s (1977) sample size determination formula for continuous data with the following
computations:
N0= t2 (pq)
d2
= (1.96)2(.25)
(.5)2
= (3.84) (.25)
(.0025)
= 384
Legend for Cochran’s sample size determination formula:
d = acceptable margin of error of +2%
(.02 X 5 point Likert-type scale)
t2 = risk willing to take
(t at .05 for N= greater than 4,000,000 is 1.96) pq = estimate of
variance in the population for a dichotomous variable
N = population size
N0 = unadjusted sample size
Criteria used in these calculations included an alpha level established “a’ priori” at the .05 level
(equivalent t value = 1.96); a conservative estimate of the variability in the population
established as .75 (equal to the product of .5 variance for each level of item); and an acceptable
margin of error (d = .05).
Due to the large defined target population, which was estimated to be 4,287,768 in 2006
(United States Census Bureau, 2008), the researcher determined that a larger sample size would
be desirable. The sample size for the current study consisted of a minimum of five hundred
responses. Data collection continued until the number of responses mandated was reached.
The sampling plan for the study included the following steps:
1. All telephone numbers registered with Louisiana telephone companies servicing an area
of the state were acquired.
2. Business and commercial listings that were included in the registered list were removed.
Multiple listings for the same address were also removed as duplicate listings.
3. Computer generated numbers provided at random from the remainder of the original
registered listing were contacted. Sample numbers were contacted only once. If no
response the next random number was called. This process was done until the minimum
number of responses (500) was met.
4. A usable response was defined as a complete list of responses to all questions in the
survey by an adult member of the household of which the information was requested.
Instrumentation
The instrument utilized in this study was based on a questionnaire found during the
review of related literature (Frick, et. al., 1995a) (See Appendix A). The instrument consisted of
fifty-five questions. This instrument consisted of three sections: demographic characteristics,
agriculture knowledge, and perception of agriculture (See Appendix B). The knowledge and
perception portions of this instrument were adapted from a similar questionnaire utilized by
Frick, et. al. (1995a). The researcher received written permission from Marty Frick, PhD, to use
and modify the original instrument for the purposes of this study (See Appendix C).
Instrument validity was examined in several ways. The original instrument was based on
eleven agriculture literacy concept areas previously identified in a Delphi study conducted by
Frick (1991). A national panel of agriculture literacy experts reviewed the instrument for content
validity and its compatibility with the key agriculture education target areas. The expert panel
found the instrument to be a valid tool for assessing the eleven agriculture concept areas. After
the pilot test associated with this previous study was conducted, the concept areas were collapsed
into seven areas based on the results of a factor analysis.
The objective of the first section of the instrument was to determine the demographic and
characteristic makeup of the population. The respondents were asked to give their answers to
questions regarding age, gender, ethnic background, location of residence (in a rural area, on a
farm, in a town, or in a city), parish of residence, occupation of the head of household and
highest level of education. The goal of the second section of the instrument was to determine the
knowledge of the agriculture industry of the respondents. Respondents were asked to indicate
whether they thought the statement was true or false. The last section of the instrument was
designed to determine the respondents’ perceptions of the agriculture industry. The respondents
were asked to indicate their level of agreement using a five point Likert-type scale. The response
scale includes the following response options: strongly disagree, disagree, neutral, agree,
strongly agree. Although the survey instrument sections that measure knowledge and perception
are similar to the original knowledge and perception survey instrument utilized by Frick, et. al.
(1995a), this section of the instrument varies from the original. The number of items utilized in
the current study was fewer than the number of items included in the original instrument. The
questionnaire was altered to include five knowledge questions within each of the four preselected
areas.
Four of the perception items were altered to reflect a connection with Louisiana. Each of
these items was altered to include a reference to the state of Louisiana. This alteration allowed
the development of a knowledge area that measured the level of knowledge of Louisiana by the
adult residents of Louisiana.
A pilot test of the survey instrument was conducted using three class sections of courses
at Louisiana State University during the spring semester of 2008. The three classes were
selected based on the diversity and cross enrollment of students from curricula across the
university and the enrollment level of the students that were enrolled in these classes. The three
classes included an upper level general studies course, a lower level course that is included in a
cross curricula minor, and a graduate level course that includes students with various ages and
backgrounds. The total number of students participating in the pilot study was eighty. The
pilot test participants were asked to make suggestions to the demographic portion of the
instrument that would allow the researcher to make changes to the instrument and make all
questions clear and understandable. The suggestions would also enable the final instrument to be
more user friendly and the results more reliable. The changes that were made from suggestions
made during the pilot study were adding more levels to the education level question, inclusion of
the age categories as seen in the pilot study, adding the option of “do not know/ uncertain” to the
knowledge portion of the survey, and a change in the perception section of the study to read
neither agree nor disagree in the place of neutral. Each of these changes was made to improve
the clarity of the items in the instrument.
Instrument reliability was assessed for both the perception and knowledge sections using
the data collected during the administration of the pilot test. The reliability was assessed by
calculating a Cronbach’s alpha for the 20 items utilized in the knowledge section of the survey
instrument and a separate Cronbach’s alpha for the 20 items included in the perception portion.
Cronbach's alpha measure of internal consistency as a reliability estimate of the knowledge scale
was determined to be α =.66. A Cronbach’s alpha measure of internal consistency computed to
measure reliability of the scale for the perception portion of this study was determined to be α=
.72, Similarly, reliability was assessed for the instrument upon completion of data collection for
the current survey. A Cronbach’s alpha measure of internal consistency of the knowledge scale
was determined to be α =.60 while the Cronbach’s alpha measure of internal consistency for the
perception scale was determined to be α =.61. According to Hair, Black, Babin, Anderson, &
Tatham (2006) these calculations were acceptable since these calculations were equal to or
greater than the minimum acceptable level of .60. The generally agreed upon lower limit for a
Cronbach’s alpha measurement is .70, although it may be decreased to .60 or lower if the
research is exploratory in nature. (Hair, et. al., 2006)
Data Collection
Data was collected using the telephone interview technique procedures suggested by
Dillman (1978). Phone surveys have been found to increase the ability to reach samples of
larger geographical populations. They have also been found to provide results at a much faster
rate than traditional methods due to the instantaneous turn around time on responses and data
collected. It can be stated that in a society where individuals are more mobile, have higher forms
of communication, and appreciate instantaneous reaction; surveys done verbally are more likely
to be completed. Time has become a valuable commodity in recent years. The time that it takes
one to fill out a paper form or fill out and submit a digital copy of a survey has become an
obstacle that surveyors are faced with. Verbal correspondence has been noted to increase
response at a significant rate (Dillman and Salant, 1994).
Phone and mail surveys have been categorized as secondary forms of gathering
information in the past. They have been described as an inferior method to the face to face
method of data collection. Low response, inability to reach the target audience group, and
shorter than necessary surveys, are all reasons against the use of phone and mail surveys. The
inability to denote the physical reactions of respondents to survey questions was noted by
Dillman (2007) as yet another shortcoming. However, the positive aspects of a phone survey
outweigh the negatives for the purpose of this study.
Researchers involved in the implementation of phone surveys must be very careful not to
mislead respondents in certain directions. Only statements and questions provided in the
instrument were utilized by the researcher. Approval for implementation of the study was
obtained from the Louisiana State University Institutional Review Board for Human Subject
Protection prior to initiation. Permission from IRB to conduct this survey was granted due to the
minimal amount of risk to respondents from participating in this survey. The study was granted
approval #E3891 (See Appendix D).
The survey was conducted during the month of February, 2008. This time period was
chosen due to the lack of activity in production agriculture in the state of Louisiana. Field grains
of rice, cotton, corn, grain sorghum, sweet potatoes, and soybeans are planted in mid spring
through early summer and are harvested in early fall. The winter commodities such as sugar
cane are planted in early fall and harvested in late fall of the following year with completion
around the new year. Other winter grain crops such as wheat are planted in mid fall and not
harvested until late spring. During the month of February all activity within the arena of
production agriculture is at a minimum. This limits the amount of recent first hand experiences
that the respondents may have with production agriculture which would affect their responses.
An instance where tractors deposited mud on roads where respondents traveled that day or ash
being deposited on home and personal belongings whose source was a sugar cane field being
burned are both examples of daily experiences which could affect the participants’ responses to
the survey.
The surveys were conducted randomly over the course of a week. The survey process
was conducted by a professional data collection service. The administrators were provided with
detailed scripts that included the fifty five items utilized in this study. The time frame of this
study included both weekdays and two weekend days. The time period that the respondents were
contacted ranged from 8:00 am- 8:00 pm each day during the selected week.
Data for this study was collected using the following steps:
1. The randomly drawn number from the sample list was called. If the researcher was
unable to make contact with the respondent or they were unwilling to participate, another
number was selected using the same random selection technique as described in the
population and sample section of this chapter.
2. Once the researcher made contact with the respondent, introduction of the researcher and
verification that the correct number was contacted was completed.
3. Verification that the number was a private residence and that an adult member of that
household was being interviewed was done.
4. The researcher provided the respondent a brief overview of the survey and its goals and
requested participation from that individual.
5. If the respondent was willing to participate and met all of the qualifications set forth in
the population and sample portion of this chapter, the researcher recorded responses to the
survey questions into a database established for the purpose of recording the responses to
the survey instrument.
6. If the respondent was willing to respond and met all of the qualifications set forth
previously, but was unable to respond at the time of the initial contact, the researcher
made note of a more appropriate time to call again. A call was returned at the appropriate
time provided by the respondent.
7. If the respondent did not qualify to answer the questionnaire the researcher contacted
another number from the population utilizing the same random selection techniques
described previously.
CHAPTER 4
FINDINGS
The purpose of this study was to determine the knowledge and perception of animal
science, plant science, environmental science, food science, processing, and policy by the adult
residents of Louisiana. The evaluations of both knowledge and perception were compared to
determine if a relationship exists between these two factors. Five hundred and forty seven
individuals participated in the study. Findings are reported in this portion of the study and are
organized by research objectives.
Objective One
The first objective was to describe the adult residents of Louisiana on selected
demographic characteristics. The respondents were asked to give personal information on the
following demographic characteristics: age, gender, ethnic background, location of residence (in
a rural area, on a farm, in a town, or in a city), parish of residence, occupation of the head of
household, and highest level of education completed.
Each of the 547 respondents was asked to report their age as of their last birthday. Five
hundred and thirty three participants responded while 14 respondents declined to provide
information regarding their age. The mean age of the respondents was 53.31 years (SD= 16.0).
The reported ages ranged from a low of 18 years to a maximum of 89 years. To further
summarize the information on age of respondents, the researcher grouped the respondents into
the following categories of age: 18-29, 30-44, 45-59, and 60 or more. These categories were
selected based on their use in previous research conducted that studied perceptions of agriculture
(Birkenholz, 1993). The age category which was reported by the largest number of participants
was the 60 or more years of age category (n= 199, 37.3%). The age category that was reported
by the smallest group of respondents was 18-29 (n=37, 6.9%). Respondents within age
categories increased with ascending age brackets (See Table 1).

60+ 199 37.3
Total 533 100.0
Note: Mean Age = 53.31, SD = 16.06
Fourteen respondents did not provide information regarding their age.
The findings of the current study differed from the demographic finding for “age” by the
United States Census Bureau (2008). In the 2000 census the largest age group in among
Louisiana residents was 35-44 years of age with 691,966 people, representing 15.5 percent of the
total population. The second largest group was 25-34 years of age with 601,162 people,
representing 13.5 percent of the population.
It was noted that people in these the ages ranging from 36 to 54 were primarily born
during the post-World War II “Baby Boom” and were a major cause of the large number of
respondents in these age categories.
Regarding respondents’ gender, 47.2% (n= 258) reported that they were male and 52.8%
(n=289) reported that they were female. All study participants responded to this item. These
findings are similar to those by the United States Census Bureau (2008) which states that the
Male population of the Louisiana was 48.4% (n= 2,162,903) and the Female population was
51.6% (n= 2,306,073).
With regard to ethnic background the majority of the respondents (n= 387, 70.7%)
indicated that they were Caucasian (See Table 2). The second largest group was those who
indicated their ethnic background as African American (n=143, 26.1%) All other ethnic
backgrounds including Hispanic, Native American, Asian, and Other were reported by less than
10% of the respondents.

ethnic background group was African American (32.5%). All other ethnic background groups
listed were Asian (1.2%), American Indian (.6%), Pacific Islander (<.001), and Other (.7%).
Participants were asked whether they considered the location of their residence (physical
location of their home) to be on a farm, in a rural area, in a town, or in a city. The responses to
this question can be found in Table 3. The category that was reported by the smallest number of
respondents was “on a farm” (n=23, 4.2%). The category that was reported by the largest number
of respondents (n=235, 43.4%) included those who considered their residence to be “in a city”.
Five participants did not respond to this item.

When asked to provide their parish of residence, all study participants responded. All
parishes in Louisiana were represented by at least one respondent, with the exception of
Cameron Parish which had no respondents in this study. The parish which was reported by the
largest number of respondents was East Baton Rouge (n=64, 11.7%). The parishes of Catahoula,
East Carroll, Red River, St. Helena, Tensas, West Feliciana, and West Carroll were each reported
by one respondent. A complete presentation of the parish of residence of respondents is
presented in Appendix E.
To further summarize information on parish of residence and to facilitate subsequent data
analysis, the parishes were grouped into regions of the state. These regions were established to
reflect the regions that were utilized in previous research conducted by Louisiana Farm Bureau
(2000). The regions consisted of Acadiana, North Louisiana, Orleans, and the Florida Parishes.
Specific information regarding which parishes are included in each of the regions can be found
in Appendix E. The region with the largest number of respondents was “Acadiana” with 181
(33.1%) participants reporting a parish of residence that was located in this region. The region
with the smallest number of respondents was “Orleans” with 46 (8.4%) participants reporting a
parish of residence that was located in this region (See Table 4).

When asked whether or not the respondent considered themselves to be the head of
household, 338 (61.8%) reported that they were the head of household. The remaining 209
(38.2%) respondents reported that they were not the head of household. The head of household
was defined as the primary wage earner for the household. All study participants responded to
this item. These findings differed from those of the United States Census Bureau (2008) that
reported the number of “Householders” to be 1,656,053 or 31.7%.
Regardless of their status as head of household, respondents were asked to report the
primary occupation/ profession of the head of the household. Due to the nature of this item, this
question was asked in a categorical manner with available responses falling into four categories.
The four response categories provided to participants were based on categories found in previous
studies conducted by the Louisiana Farm Bureau (Kennedy, 2004). These categories included
Laborer, Sales/ Clerical/ Technical, Administrative/ Professional, and Other. The category of
“Other” was provided for those participants who felt that the occupation of their head of
household did not fit into any of the three other options. All of the participants did not respond
to this question with 30 respondents leaving the item blank.
The largest number of respondents (n = 262, 50.7%) reported their head of household’s
occupation would be most appropriately described as “Laborer”. In addition, 215 (41.6%)
respondents reported their head of household’s occupation would most appropriately be
described as “Sales/ Clerical/ Technical”. These two categories combined to total 92.3% (n=477)
of the participants responses. Table 5 includes the number of respondents in each category.

When asked to report their highest level of education completed, respondents were asked
to answer with one of the seven categories provided. These categories included “Less than High
School”, “High School Graduate”, “Some College”, “College Graduate- Non-Agriculture
Degree”, “College Graduate- Agriculture or Related Degree”, “Post Graduate- Non-Agriculture
Degree”, or “Post Graduate- Agriculture or Related Degree”. Six respondents did not identify
their educational level completed. The highest level of education completed by the largest group
of participants (n=142, 26.3%) was “College Graduate- Non-Agriculture Degree”. Results
showed 356 (65.8%) respondents reported that they had obtained an educational level of some
college or higher as their highest level of education completed. Those who had obtained a
degree in agriculture were reported in two groups and totaled 18 respondents (3.3%). These two
groups were “College Graduate- Agriculture or Related Degree” (n=14, 2.6%) and “Post
Graduate- Agriculture or Related Degree” (n=4, .7%). A detailed listing of the educational levels
and the number of respondents reporting each can be found in Table 6.

Objective Two
The second objective of the study was to determine the knowledge of the adult residents
of Louisiana regarding five areas of agriculture industry. To accomplish this objective,
participants were asked to respond to 20 items designed to measure their knowledge of
environmental science, plant science, animal science, processing, and policy. A listing of the
twenty items used to measure the respondents’ knowledge in these areas with the correct answer
identified is provided in Appendix F. Respondents were asked to indicate that each item was
either “true”, “false”, or that they “do not know/ uncertain”. Each item was scored as either
correct or incorrect. Responses of “do not know/ uncertain” were scored as incorrect. A
summary of the number of correct and incorrect responses to the items are presented in Table 7.
Among the twenty items, the statement that was responded to correctly by the largest
number of respondents was the statement “Hamburger is made from the meat of pigs”. The
correct response was noted by 92.5% (n= 506) of the respondents. The item that was

Note: Items receiving a response of “do not know/ uncertain” were recorded as incorrect
responded to correctly by the second largest number of respondents was the statement
“Processing increases the cost of food products” (n=483, 88.3%). When asked to indicate
whether the statement “Food safety is a major concern of the food processing industry” was true
or false 457 (83.5%) of the respondents answered correctly with true as their response. This item
received the third largest number of correct responses.
The items that received the smallest number of correct responses were: “Homogenizing
kills bacteria in milk with heat” (n=116, 21.2%) and “Forestry is the leading agricultural industry
in the state of Louisiana” (n=254, 46.4%).
To further summarize the information on knowledge of agriculture among adult residents
of Louisiana, the researcher computed an overall knowledge score for each participant in the
study. To compute this score, the researcher coded each correct response as “1” and each
incorrect response as “0”. The responses to the 20 items on the scale were then summed for each
respondent. Therefore, the possible overall agriculture knowledge scores ranged from a low of 0
(no correct responses) to 20 (all correct responses). The calculated scores ranged from a low of 5
to a high of 20. The overall mean agriculture knowledge scores of adult residents of Louisiana
was 13.60 (SD=2.743).
In addition to an overall knowledge score, the data from the knowledge scale was
summarized into five scales designed to be measured in the measuring instrument. These
subscales included environmental science, policy, plant science, animal science, and processing.
The subscales utilized were five of the seven predetermined areas of agricultural knowledge as
proposed by Birkenholz (1993). Four questions were asked within each subscale area. Four
questions were also asked in order to measure the knowledge of respondents on agricultural
subject areas specifically associated with the state of Louisiana, bringing the number of subscales
to six. These Louisiana questions were overlapped with the five predetermined areas previously
mentioned and were utilized in the calculations of both the predetermined subscale scores as well
as in the Louisiana subscale score. A detailed list of the questions associated with each of the
five predetermined areas with the number of correct and incorrect responses to each item can be
found in Table 8.
A subscale score was computed for each respondent in each agricultural knowledge area
measured. The sub-scales were defined as the total number of correct responses in each

The mean subscale score was then computed for each of the six defined subscales across all
respondents. This information is presented in Table 9 including the mean and standard deviation
for each subscale as well as the minimum and maximum respondent score for each of the
measurements.
Analysis of the computed mean subscale scores revealed that the respondents had the
highest level of knowledge in the subscale of environmental science (M = 3.07, SD= .959) and
the lowest reported level of knowledge in the subscale of processing (M = 2.51, SD= .828).

Objective Three
Objective three of this study was to determine the perceptions of the agriculture industry
among adult residents of Louisiana. Participants were asked to respond to a 20 item scale
(Birkenholz, 1993) designed to measure perceptions of agriculture. Study participants were
asked to indicate their level of agreement or disagreement with each of the scale items using a
five-point Likert-type scale with the following response values: Strongly Disagree=1,
Disagree=2, Neither Agree nor Disagree=3, Agree=4, Strongly Agree=5. The mean response
value for each of the items was calculated and is presented in Table 10. To interpret the responses
to the items the researcher designed an interpretive scale based on the scale response values as
follows: Strongly Disagree =1-1.5, Disagree =1.51-2.5, Neither Agree nor Disagree =2.51- 3.49,
Agree = 3.50-4.49, Strongly Agree =4.5-5.
The item with the highest level of agreement was “Not all land is suitable for farming”
(M = 4.22, SD = 1.002). This mean response value was classified in the “agree” category using
the researcher designed interpretive scale. The item with the second highest level of agreement
was “Louisiana farmers should develop new innovative marketing strategies” (M = 4.16, SD =
.839). This item was also classified in the “agree” interpretive category.
The item which had the highest level of disagreement was “farmers earn too much
money” (M = 1.61, SD = .898). This item was classified in the “disagree” interpretive category.
Overall, nine items were classified in the “agree” category, six were classified in the “neither
agree nor disagree” category, and five were in the “disagree” category. See Table 10.
In order to further summarize the information regarding the respondents’ perception of
agriculture the scale was factor analyzed to determine if any underlying constructs exist in the
scale based on responses provided. The method used was the principal components analysis with
a varimax rotation.

Several of the questions were designed such that a ‘disagree’ response indicated a more
positive perception of agriculture. For this reason, the researcher reversed the scale on these
items prior to the identification of subscales so that for all scale items a higher response value
indicated a more positive perception of the agriculture industry. For example, the more positive
response to the statements “Agriculture is the greatest polluter of our water supply in Louisiana”
and “Farmers earn too much money” was the response of “Strongly Disagree”. All of the
perception items are listed in Appendix G with the answer exhibiting a more positive perception
of agriculture noted.
Prior to conducting the planned factor analysis, the researcher examined the cases-
tovariable ratio (28.7:1) which met the minimal cases-to-variable ratio recommended by Hair et
al.,
(2006). A review of the anti-image correlation matrix revealed measures of sampling adequacy
(MSA’s) all above the 0.5 threshold. Furthermore, a Kaiser-Meyer-Olkin (KMO) Measure of
Sampling Adequacy was conducted and calculations revealed a KMO value of .636. KMO
values above 0.5 determine sampling to be adequate (University of Newcastle Upon Tyne, 2006).
In addition, a Bartlett’s Test of Sphericity was performed to test the hypothesis that the variables
in the population correlation matrix are uncorrelated. The strength of the relationships between
variables was found to be strong and acceptable for factor analysis based on results of this test
(X2(df=190, n=20) = 918.100, p < .001), University of Newcastle Upon Tyne, 2006).
All measures indicated that the data from this scale were adequate and appropriate for calculation of
a factor analysis and well exceeded the minimal sample size and the minimal cases-to-variable ratio
(Hair, et al., 2006).
After the determination that the data was adequate for completing an exploratory factor
analysis, the next step in conducting the test was to determine the number of factors to be
extracted from the perception scale. The researcher used a combination of the latent root
criterion, the scree test criterion, and the percentage of variance explained to make this decision.
When the scree test was analyzed, the number of factors was interpreted to be four, five, or six.
The researcher examined each of these factor grouping models and determined the four factor
solution to be the most conceptually meaningful and contained the least amount of cross loadings
for the items in the survey. Hair, et al. (2006) states that factor loadings are reflective of the
sample size and for a sample size of 350 or greater a factor loading of .30 is significant. Each
factor was significant with a loading of at least .30, with the exception of one statement. The
statement “A strong agriculture industry is more important than military power.” did not meet the
minimal statistical loading strength of .30 in the four factor model in any of the four identified
factors with an actual loading of .19. This survey item was excluded from the scale due to the
low loading strength. A detailed description of the factor loadings of each item can be found in
Table 11.

Note: * = Factor Loadings <.10 Four subscales were identifiable and were determined to be
underlying constructs of the perceptions of agriculture. The four factor model explained 35.24%
of the total explained variance. The researcher labeled the four subscales as follows: “Attitude
Toward Farming”, “Issues Relating to Food Supply”, “Farming Practices”, and “Food Prices”.
The first factor identified was labeled by the researcher to be “Attitude Toward
Farming”. This factor included items related to farmers income, negative effect of
farming on the environment, governmental control over faming, and animal rights; A
total of five items with loadings ranging from .628 to .397 were included in this factor,
and it explained 11.8% of the total variance in the scale. The second factor identified in
the scale was labeled by the researcher as “Issues Relating to Food Supply”. This factor
included six items related to changes in crop yields, land usage for farming, employment
within the agriculture sector, new markets for crops, and the geographic movement of
citizens. The factor loadings for this subscale ranged from a high of .572 to a low of .370
and explained 9.056% of the overall scale variance. The third factor identified items that
reflected perceptions of “Farming Practices” and explained 7.811 percent of the total
variance. The loadings ranged from .687 to .447 and included four items: pesticide use,
practices of raising livestock, organic farming practices and the utilization of free trade in
commodity markets. This factor was labeled by the researcher as “Farming Practices”.
The fourth factor added an additional 6.569% of explained variance and had factor
loadings ranging from .642 to .391. This factor included items that discussed income
spent on food, grains as an energy source, and farmer control over prices. This factor was
labeled as “Food Prices” by the researcher.
In order to more adequately describe the four subscales identified from the factor
analysis, the researcher computed subscale scores for each of these constructs. Each of the
subscale scores are defined as the mean of the items included in each respective subscale.
The mean score was chosen over a summated measure due to the varying number of items
in each factor. The computed mean scores for the various factors were found to range
from a high of 3.81 for the factor titled “Attitudes Toward Farming” to a low value of 3.14
for the factor labeled “Food Prices”. Each of the factor subscales had a possible minimum
value of one and a possible maximum value of five. The subscale scores are presented in
Table 12.

Objective Four
Objective four of the study was to determine if a relationship exists between knowledge
of selected aspects of the agriculture industry and perceptions of the agriculture industry
among adult residents of Louisiana. In order to accomplish this objective, Pearson’s
Product Moment Correlations were calculated to determine the strength and direction of the
relationship between the knowledge of agriculture subscale scores measured in the study
and the perception of agriculture subscale scores. Davis (1971) descriptors of
association were used to describe the bivariate correlations. These descriptors included .70
or higher = “very strong association”; .50- .69 = substantial association”; .30 - .49 =
“moderate association”; .10 - .29 = “low association”; and .01 - .09 = “negligible”. The
alpha level for significance of correlations was established “a’ priori” as .05.
Many of the relationships between knowledge and perception were significant and
were described as low to moderate based on Davis’ (1971) descriptors. A complete
presentation of the correlations between the knowledge and perception subscales can be
found in Table 13.
When examining the relationship between the knowledge subscale “Policy”, and the
perception subscales, the highest association was with the perception subscale “Issues
Relating to Food Supply” (r= .21, p= <.001). The nature of this relationship was such that
higher levels of knowledge regarding “Policy” were associated with more positive
perceptions regarding “Issues Related to Food Supply”. Two additional perception
subscales were found to be significantly related to the “Policy” subscale score. These
include “Farming Practices” (r=.11, p=.01) and “Food Prices” (r=.09, p=.03).
In examining the relationship of the knowledge subscale “Environmental Science”
with the perception subscale scores, all of the correlations were found to be statistically
significant. The highest association was with the “Issues Relating to Food
Supply” (r= .23, p<.001). The next highest association was with the “Attitude Toward
Farming” subscale (r=.22, p<.001). Based on Davis’ (1971) descriptors, all of the
relationships between the “Environmental Science” knowledge subscale and the perception
subscale scores were described as “Low Associations”. Additionally, all of these associations
were positive, indicating that higher levels of knowledge in the “Environmental Science”
subscale were associated with more positive perceptions of agriculture in each of the
identified subscales (See Table 13).

Examination of the relationship between the knowledge subscale “Plant Science” and
perception subscale scores revealed that all of the correlations were statistically significant.
The highest association was with the subscale “Issues Relating to Food Supply” (r=.20,
p<.001) (See Table 13). Based on Davis’ (1971) descriptors, all four of the relationships
between the “Plant Science” knowledge subscale and the perception subscales were
described as “Low Associations”. These four perception subscales include “Issues Relating
to Food Supply”, “Attitude Toward Farming”, and “Farming Practices”. All of the
relationships with “Plant Science” were positive such that a higher level of knowledge in the
“Plant Science” subscale was associated with a more positive perception of agriculture.
In examining the relationship of the knowledge subscale “Animal Science” with
the perception subscale scores, one of the correlations was found to be statistically
significant. That association was with the perception subscale “Issues Relating to Food
Supply” (r= .12, p= .01). Based on Davis’ (1971) descriptors, the association between the
“Animal Science” knowledge subscale and the “Issues Relating to Food Supply”
perception subscale score was described as a “Low Association”. This association was
also positive indicating that a higher level of knowledge in the “Animal Science” subscale
was associated with a more positive perception of agriculture in the subscale “Issues
Relating to Food Supply” (See Table 13).
In examining the relationship between the knowledge subscale “Processing” and the
perception subscale scores, one correlation was found to be statistically significant.
This association was with the perception subscale “Issues Relating to Food Supply” (r=.09,
p=.03) (See Table 13). Based on Davis’ (1971) descriptors, this relationship was described
as a “Negligible Association”.
Examination of the relationship of the knowledge subscale “Louisiana” with the
perception subscale scores revealed statistically significant correlations with each of the four
perception subscales. The highest association was found between the knowledge subscale
“Louisiana” and the perception subscale “Food Prices” (r=.17, p=<.001). The second
highest association was with the perception subscale “”Issues Relating to Food Supply” (r=
.12, p= .01) (See Table 13). Based on Davis’ (1971) descriptors, the relationships between
the “Louisiana” knowledge subscale and the perception subscales “Food Prices”, Farming
Practices”, and “Issues Relating to Food Supply” were described as “Low Associations”.
Additionally, these associations were positive indicating a higher level of knowledge on the
“Louisiana” subscale was associated with more positive perceptions of agriculture in the
subscales “Food Prices”, “Farming Practices”, and “Issues Relating to Food Supply”. The
relationships between the “Louisiana” knowledge subscale and the perception subscale
“Attitude Toward Farming” was described as a “Negligible Association”. This association
was also positive indicating that a higher level of knowledge in the “Louisiana” subscale
was associated with more positive perceptions of agriculture in the identified subscale
“Attitude Toward Farming”.
Objective Five
Objective five was to determine if relationships exist between perceptions of the
agriculture industry and selected demographic characteristics of adult residents of
Louisiana. The demographic characteristics included in this objective were age, gender,
ethnic background, location of residence, parish of residence, occupation of the head of
household, and highest level of education received. The statistical test used to measure
the association between these demographic characteristics and each of the perception
subscales was selected based on the appropriateness of the test for the level of
measurement of each variable as well as to maximize the interpretability of the results.
In examining the relationship between perceptions of the agriculture industry and
selected demographic characteristics, the researcher utilized the mean scores associated
with each of the subscales previously identified. These mean scores were computed on
the subscales “Attitude Toward Faming”, “Issues Relating to Food Supply”, “Farming
Practices”, and “Food Prices”.
The first demographic characteristic examined for relationships with the perceptions
of agriculture was age. The statistical procedure used to measure these relationships was
the Pearson’s Product-Moment Correlation Coefficient. Two of the perceptions of
agriculture subscale scores were found to be significantly related to the age of
respondents. The highest association identified was with the “Food Prices” subscale (r =
.16, p <.001). This correlation was classified as a “Low Association” using Davis’
descriptors (Davis, 1971). The nature of the relationship was such that respondents who
were older tended to have more positive perceptions of agriculture on the “Food Prices”
subscale.
The other subscale that was found to be significantly correlated with age was the
“Issues Relating to Food Supply” score (r= -.12, p= .004). This correlation was also
classified as “Low” (Davis, 1971). The nature of this relationship was such that younger
respondents tended to have more positive perceptions of agriculture on the “Issues Relating
to Food Supply” score. The other two perception subscale scores were not significantly
related to the age of respondent (See Table 14).
Due to the dichotomous nature of the variable gender, the relationship between the
perception of agriculture in Louisiana and the variable gender was determined using the
independent t-test. Results from this test indicated there was a statistically significant
difference between males and females in their perception of agriculture related to the
subscales “Attitude Toward Farming”, “Issues Dealing with Food Supply”, and “Farming

Practices”. Each of these three differences were significant at p <.001. Additionally, the
perception subscale “Food Prices” was slightly significantly different between males and
females (p=.049). The nature of all of the significant differences was such that male
respondents tended to have more positive perceptions of agriculture than the female
respondents (See Table 15).

In examining the relationship between the perception of agriculture among adult residents
of Louisiana and the variable ethnic background, a t-test was utilized. This test was
selected based on the use of only the two ethnic groups African American and Caucasian.
The groups of Hispanic, Asian, Native American, and Other were not included in this
measurement due to the small number of respondents in each of these categories (Hispanic,
n=8; Native American, n=7; Asian, n=1; Other, n=1). The means, standard deviations, and
significance for each of the perception subscales can be found in Table

It should be noted that the Levene’s Test for Equality of Variance revealed that the
Ethnic Background groups (African American and Caucasian) had significantly different
variances for two of the perception subscale scores, “Attitude Toward Farming” (F =
4.078, p = .044) and “Farming Practices” (F= 9.682, p = .002). Therefore, for these two
subscales, the t-value used was with equal variances not assumed.
Results of the t-tests indicated that there was a significant difference between the two
ethnic groups with relation to all of the perception subscales (See Table 16). These
differences were such that those respondents indicating their Ethnic Background to be
Caucasian tended to have more positive perceptions of agriculture than those respondents
that indicated their Ethnic Background to be African-American in each of the subscales.
The greatest difference between the two Ethnic backgrounds was found in the perception
subscale “Attitude Toward Farming” (t219.36 = 4.90, p, .001).
Examining the relationship between the perception of agriculture in Louisiana and
the location of residence (on a farm, in a rural area, in a town, or in a city) among adult
residence of Louisiana was accomplished by utilizing one way analysis of variance tests.
Results of the analysis of variance tests comparing perception of agriculture subscale scores
by location of residence indicated that at least one significant difference existed among the
four groups on the subscale “Food Prices” (F= 2.961, p= .032) (See Table 17).
A Tukey’s Post-hoc test was used to identify the specific group means that were
significantly different. A detailed listing of this difference can be found in Table 18.

To examine the relationship between parish of residence and perception of agriculture
among adult residents of Louisiana, the researcher grouped the parishes into geographic
regions. This grouping was needed since the number of respondents in each parish was
insufficient to permit individual parish comparisons. These areas are a reflection of the
geographical areas that are utilized by farm bureau in order to separate areas into logistically
accessible work regions. Analysis of the relationship between the perception of agriculture
and the parish of residence was accomplished by comparing the four perception subscale
scores by geographic region (as a measure of parish) using one way analysis of variance
tests. No significant differences were found among the four geographic regions with regard
to their perceptions of the agriculture industry in
Louisiana. These differences are found in Table 20.

Another variable that was examined to determine if it was related to the perceptions of
the agriculture industry was the occupation of the head of household. This variable was
self reported in four categories which included “Laborer”, “Sales/ Clerical/ Technical”,
“Administrative/ Professional”, and “Other”. To measure this relationship, the researcher
chose to compare the perception sub-scale scores by categories of the occupation of head
of household using the one-way analysis of variance procedure. Of the four sub-scale
scores compared, a statistically significant difference was found in one of the scores. A
Significant F test indicated that there was at least one significant difference among the
groups on the sub-scale score “Attitudes Toward Farming” (see
Table 22). No significant difference was found in the other three sub-scale sores (see
Table 21).

To identify specifically which groups of the occupation of head of household were
significantly different on the “Attitude Toward Farming” perception subscale score, the
researcher used the Tukey’s Post Hoc analysis test. Results of this test (See Table 23)
revealed that the group “Laborer” (M = 3.69, SD = .8257) was significantly different
from the “Sales/ Clerical/ Technical” group (M = 3.89, SD = .6591) and the
“Professional/ Administrative” group (M = 4.03, SD = .6625). The nature of this
difference was such that both “Sales/ Clerical/ Technical” group and the “Professional/
Administrative” group had more positive perceptions of the agriculture industry in the
“Attitudes Toward Farming” sub-scale that the “Laborer” group.

A Tukey’s Post Hoc multiple comparison test was used to identify the specific
groups which were significantly different (See Table 26). This test revealed that
participants who reported their highest level of education completed as “Post Graduate-
Agriculture or Related Degree” had significantly more positive perceptions on the items
in the “Attitude Toward Farming” subscale than those who reported their highest level of
education as “Less than High School”. The second subscale that was found to have a
significant difference among the education categories was “Food Prices” (F= 2.176, p=
.044) (See Table 27). A Tukey’s Post Hoc multiple comparison test was used to identify
the specific groups which were significantly different. Although the Analysis of
Variance test showed a significant F value, when Tukey’s Post Hoc multiple comparison
test was applied to the data no significant differences were found to exist (See Table 28).

Objective Six
Objective six was to compare the perceptions of the agriculture industry among adult
residents of Louisiana by whether or not the respondent had completed a college degree in
an agricultural field. Of the respondents, 18 (3.3%) stated that they had received a college
degree in an agriculture or related field while the remaining 523 (95.6%) stated that they
had not. Of those respondents that stated they obtained a college degree in an agriculture
or related field, 14 (2.6%) obtained an undergraduate degree while 4 (.7%) obtained a
graduate level degree in agriculture or related field.
Independent t-tests were used to accomplish this objective due to the dichotomous
nature of the independent variable. Each of the perception subscales scores were
compared by levels of the independent variable. None of these tests revealed a significant
difference between the group who indicated that they had completed a college degree in
an agriculture or related field and the group that indicated that they had not completed a
college degree in an agriculture field. (See Table 29)

Objective Seven
Objective seven was to compare the perception of the agriculture industry among adult
residents of Louisiana by whether or not the respondent had prior agricultural training
(defined as whether or not the respondent indicated that they enrolled or participated in
any agriculture course(s) during high school or college, such as FFA, 4-H, or other
activities). This was measured by whether or not the respondent held membership in FFA
and/or 4-H.
Of the five hundred forty seven individuals who provided complete data, three hundred
twenty two (58.87%) respondents stated that they did not have prior agriculture training
such as participation in either FFA, 4-H, or other activities. Two hundred twenty five
(41.13%) respondents stated that they had prior agriculture training such as membership in
at least one of the organizations.
Independent t-tests were used to accomplish this objective due to the dichotomous
nature of the independent variable, prior agricultural training. Each of the four perception
subscale scores were compared by the levels of the independent variable. None of these
tests revealed a significant difference in the perception subscale scores between those
with prior agricultural training and those that did not have this type of training. Complete
results of the t-tests can be found in Table 30.

Objective Eight
This objective was to compare the perceptions of the agriculture industry among adult
residents of Louisiana by whether or not the respondent had prior agriculture
experience (defined as whether or not the respondent indicated that they are currently a
member of Louisiana Farm Bureau). Five hundred and forty respondents reported their
membership, or lack thereof, in Farm Bureau while seven respondents did not answer this
item. It was noted that 56 (10.0%) respondents acknowledged that they are currently
members of Louisiana Farm Bureau, while 484 (90.0%) of the respondent group stated that
they were not members of Farm Bureau.
In order to accomplish this objective independent t-tests were used due to the
dichotomous nature of the independent variable “Prior Ag Experiences”. Each of the four
perception subscale scores were compared by the levels of the independent variable.
These tests revealed two significant differences in respondent perceptions of agriculture.
These differences were in the perception subscales “Issues Relating to Food Supply” (t=
2.350, p= .019) and “Food Prices” (t= 2.306, p= .022). The differences in perception with
regard to prior agriculture experience as measured by current membership in Farm
Bureau can be seen in Table 31.
These significant differences were such that a more positive perception for “Issues
Relating to Food Supply” and “’Food Prices” was held by those respondents who held
membership in the Farm Bureau Organization.

Objective Nine
Objective nine was to determine if a model exists explaining a significant portion of the
variance in perceptions of the agriculture industry among adult residents of
Louisiana from selected measures.
To accomplish this objective, the researcher used the multiple regression analysis
statistical procedure. A multiple regression analysis was performed separately for each of
the perception of agriculture subscale scores derived during the factor analysis. The
subscale scores were defined as the mean of the items included in each of the identified
factors. The selected demographic variables and knowledge subscale scores were used as
independent variables in each analysis. These variables were entered into the analysis
using stepwise entry of the variables due to the exploratory nature of the influence that
these variables had on the perception of agriculture subscale scores.
The following measures were entered as independent variables into the regression
analysis:
a. knowledge of adult residents of Louisiana regarding selected aspects of the
agricultural industry.
b. age
c. gender
d. ethnic background
e. location of Residence (in a rural area, on a farm, in a town, in a city)
f. parish of Residence
g. occupation of the head of household
h. highest Level of Education
The five independent variables that were measured as categorical data were
recoded to create a dichotomous variable from each level of the variable. The recoded
variables included ethnic background, location of residence, parish of residence,
occupation of the head of household, and highest level of education completed. Gender
was a naturally dichotomous variable and did not need recoding. The independent variable
of age was continuous in nature and also did not need recoded.
The first independent variable that needed to be recoded as a series of dichotomous
variables was ethnic background. This variable included six different ethnic background
responses from the study participants. However, all but two of these categories included
very small numbers of respondents (less than ten). Therefore, the researcher decided to
use recoding procedures to establish two ethnic background variables. These variables
were African American and Caucasian, and each of them was defined as whether or not
the respondent was identified as being a member of that ethnic background. For example,
the variable African American was defined as whether or not the respondent identified
himself as a member of this group, and all respondents were classified as either African
American or not African American. The same procedure was used to establish the variable
Caucasian.
For those categorical variables with three or more response categories available,
each respondent was coded as either having or not having the trait represented by each of
the available response categories. The variable location of residence had four response
categories. A separate variable was created for each of the four response categories (in a
rural area, on a farm, in a town, and in a city) with participants classified as having
reported that their residence either was or was not classified as each of the categories. For
example, a variable was created for the category “On a Farm” with all participants who
responded to this item classified as reporting that they resided or did not reside on a farm.
Each of the variables was entered into the analysis utilizing stepwise entry.
The variable “Level of Education” was naturally categorical in nature. A separate
variable was created for each of the seven response categories (Less than High School, High
School Degree, Some College, College Graduate- Non Agriculture, College
Graduate- Agriculture or Related Field, Post Graduate- Non Agriculture, Post Graduate-
Agriculture or Related Field). Each of the respondents was recoded as either having or
not having each of the six educational levels as their highest educational level achieved.
Due to the small number of respondents that indicated their highest level of education
completed to be “Post Graduate- Agriculture or Related Field” (n = 4, .07%), this variable
was removed from the analysis. Each of the remaining variables was entered into the
analysis utilizing stepwise entry.
Similarly, the respondents were provided with four head of household occupation
categories. A separate variable was created for each of the four response categories
(Sales/ Clerical/ Technical, Professional/ Administrative, Laborer, and Other) with
participants classified as having reported that their occupation was or was not classified as
belonging to that category. The responses for each of these variables were entered into
the analysis utilizing stepwise entry.
The independent variable Parish of Residence was previously categorized into four
geographical areas as recognized in previous studies commissioned by the Louisiana
Farm Bureau. The four regions included “Orleans Area”, “Florida Parishes”, “Acadiana”,
and “North Louisiana”. These four regions were recoded into four established separate
dichotomous variables. Each respondent was classified as either residing or not residing
in a geographic region. Each of the four dichotomous variables was then entered into the
regression analysis.
The first dependent variable to be analyzed in this portion of the study was the
perception subscale “Attitude Toward Farming”. The first step in the analysis was the
researcher’s examination of the data for the presence of excessive multicollinearity among
the independent variables in the analysis. This was accomplished through the
examination of the tolerance values and the variance inflation factor (VIF) for the data
included in the analysis.
The independent variable “Ethnic Background- African American” held the lowest
tolerance (.148) and the highest variance inflation factor (VIF= 6.780). The tolerance
values ranged from .148 to .992, and the VIF values ranged from 6.780 to 1.008 (see
Table 32). Hair, et al., (1998) indicated that, “A common cutoff threshold is a tolerance
value of .10”. A tolerance value of .10 would correspond to a VIF of 10.0.
Since the tolerance values and the VIF values were within acceptable ranges, the researcher
concluded that no incidences of excess co- linearity were found in the data.

Two way correlations between factors used as independent variables in the regression and
the dependent variable are presented for descriptive purposes. These correlations can be seen
in Table 33. The correlations between the twenty seven variables used as independent
variables in the analysis and the dependent variable “Attitude Toward Farming” perception
sub-scale score were examined and thirteen were found to be statistically significant. Of
these thirteen variables, six variables were highly significant (<.001) and included
Knowledge Subscale- Environmental Science, Gender,
Ethnic Background- African American, Ethnic Background- Caucasian, Education Level-
Less Than High School, and Education Level- High School Graduate. These associations are
found in Table 33.

A stepwise regression analysis was conducted utilizing the probability of F to enter at
.05 and the probability of F at .10 to be removed from the equation. The variables were
entered into the analysis using the stepwise method. The first variable to enter the model
was the Knowledge Subscale- Environmental Science, and it explained 5.3% (F change =
29.690, p= <.001) of the variance in the perception subscale score “Attitude Toward
Farming”. Additionally, the variable “Ethnic Background- Caucasian” explained 3.4% (F
change = 19.432, p = <.001) of the variance, the variable Gender explained 1.4% (F
change = 8.166, p = .004) of the variance, and the variable Occupation of the head of
household- Sales, Clerical, Technical explained 1.3% (F change = 7.583, p = .006). The
remainder of the variables accounted for less than 1.0% of the variance each with Parish
of Residence- Orleans explaining 0.9% (F change = 5.530, p = .019) and Educational
Level- Less Than High School explaining 0.8% (F change = 5.010, p = .026) of the
variance in the model. Combined these six variables explained 13.1% of the variance in
the perception subscale “Attitude Toward Farming”.
The nature of the influence of these variables that entered the model was such that
respondents with higher subscale scores in the knowledge area of “Environmental Science”,
denoted their ethnic background to be “Caucasian”, or stated their Head of household’s
occupation to be in the category of “Sales/ Clerical/ Technical” tended to have higher scores
in the perception subscale “Attitude Toward Farming”. The influence of the variable
gender was such that Males tended to have higher scores in the perception subscale
“Attitude Toward Farming”. Additionally, the influence of the variables that entered the
model was such that respondents denoting their Parish of Residence in the Orleans region
or their highest educational level received as “High School Graduate” tended to have lower
scores in the perception subscale “Attitude Toward Farming”. Table 34 presents the results
of the multiple regression analysis utilizing the perception subscale “Attitude Toward
Farming” as the dependent variable.

The second dependent variable to be analyzed in this portion of the study was the
perception subscale “Issues Relating to Food Supply”. The first step in the analysis was the
researcher’s examination of the data for the presence of excessive multicollinearity among
the independent variables in the analysis. This was accomplished thought the examination
of the tolerance values and the variance inflation factor (VIF) for the data included in the

A stepwise regression analysis was conducted utilizing the probability of F to enter
at .05 and the probability of F at .10 to be removed from the equation. Each variable was
entered into the analysis using a stepwise regression method. The variable
“Knowledge Subscale- Environmental Science” entered the analysis and explained 5.5%
(F change = 30.594, p= <.001) of the variance in the perception subscale score “Issues
Relating to Food Supply”. When the remaining variables were entered into the analysis,
the variable “Gender” explained 3.4% (F change = 19.737, p = <.001) of the variance, the
variable “Knowledge Subscale-Policy” explained 1.5% (F change = 8.941, p = .003) of
the variance, and the variable “Ethnic Background-Caucasian” explained 1.4% (F change
= 8.165, p = .004). The remainder of the variables accounted for less than 1.0% of the
variance each with “Parish of Residence- Acadiana” explaining 0.7% (F change = 3.989, p
= .046) and “Educational Level-High School Graduate” explaining 0.6% (F change =
3.886, p = .049) of the variance in the model. Combined these six variables explained
13.1% of the variance in the perception subscale “Issues Relating to Food Supply”.
The nature of the influence of these variables that entered the model was such that
respondents with higher subscale scores in the knowledge areas of “Environmental
Science” or “Policy”, denoted their ethnic background to be “Caucasian”, or stated their
Parish of Residence as Acadiana tended to have higher scores in the perception subscale
“Issues Relating to Food Supply”. Additionally, those respondents who denoted their
Gender to be “Male” tended to have higher perception scores on the subscale” Issues
Relating to Food Supply”. Those respondents who denoted and their educational level to
be “High School Graduate” tended to have lower scores in the perception subscale “Issues
Relating to Food Supply” due to their inverse relationship. Table 37 presents the results
of the multiple regression analysis utilizing the perception subscale “Attitude Toward
Farming” as the dependent variable.

The third dependent variable to be analyzed in this portion of the study was the
perception subscale “Farming Practices”. The first step in the analysis was the researcher’s
examination of the data for the presence of excessive multicollinearity among the
independent variables in the analysis. This was accomplished thought the examination of
the tolerance values and the variance inflation factor (VIF) for the data included in the
analysis. The independent variable “Ethnic Background- African
American” held the lowest tolerance (.148) and the highest variance inflation factor (VIF=
6.740). The tolerance values ranged from .148 to .998, and the VIF values ranged from
6.740 to 1.002 (see Table 38).
Hair, et. al. (2006) indicated that, “A common cutoff threshold is a tolerance value
of .10” (p.193). A tolerance value of .10 would correspond to a VIF of 10.0. Since the
tolerance values and the VIF values were within acceptable ranges, the researcher
concluded that no incidences of excess co -linearity were found in the in the data.

Two way correlations between factors used as independent variables in the
regressions were analyzed for descriptive purposes. These correlations between
independent variables can be seen in Table 39. The twenty seven variables were examined
and nine were found to have significant two-way associations with the
Perception. Those variables found to have this significant association included
Knowledge Subscale-Policy, Knowledge Subscale-Environmental Science, Knowledge
Subscale-Plant Science, Knowledge Subscale-Louisiana, Gender, Ethnic BackgroundAfrican
American, Ethnic Background-Caucasian, Location of Residence-In a City, and Educational
Level-Less Than High School.
A stepwise regression analysis was conducted utilizing the probability of F to enter at
.05 and the probability of F at .10 to be removed from the equation. Each variable was
entered into the analysis using a stepwise regression method. The variable “Gender”
entered the analysis and explained 3.6% (F change = 19.894, p= <.001) of the variance in
the perception subscale score “Farming Practices”. When the remaining variables were
entered into the analysis, the variable “Ethnic Background-Caucasian” explained 1.9% (F
change = 10.732, p = .001) of the variance, and the variable
“Knowledge Subscale-Environmental Science” explained 1.4% (F change = 7.795, TABLE

For all recoded dichotomous variables: 1 = presence of the trait and 0 = absence of the trait
a Male = 1, Female = 2 p = .005). Combined these three variables explained
6.9% of the variance in the perception subscale “Farming Practices”.
The nature of the influence of these variables that entered the model was such that
respondents with higher subscale scores in the knowledge areas of “Environmental
Science” or denoted their ethnic background to be “Caucasian” tended to have higher
scores in the perception subscale “Farming Practices”. Additionally, those respondents that
denoted their Gender to be “Male” tended to have higher scores in the perception subscale
“Farming Practices”. Table 40 presents the results of the multiple regression analysis
utilizing the perception subscale “Farming Practices” as the dependent variable. The
fourth dependent variable to be analyzed in this portion of the study was the perception
subscale “Food Prices”. The first step in the analysis was the researcher’s examination of
the data for the presence of excessive multicollinearity among the

independent variables in the analysis. This was accomplished thought the examination of the
tolerance values and the variance inflation factor (VIF) for the data included in the analysis.
The independent variable “Location of Residence-In a Town” held the lowest
tolerance (.220) and the highest variance inflation factor (VIF= 4.539). The tolerance
values ranged from .220 to .897, and the VIF values ranged from 4.539 to 1.013 (see Table
41). Hair, et al. (1998) indicated that, “A common cutoff threshold is a tolerance value of

CHAPTER 5
SUMMARY
Summary of Purpose and Specific Objectives
The purpose of this study was to determine the knowledge of animal science, plant
science, environmental science, food science, processing of food, and Louisiana by the
adult residents of Louisiana. The second purpose of this study was to determine the
perception of “Attitude Toward Farming”, “Issues Relating to Food Supply”, “Farming
Practices”, and “Food Prices” by the adult residents of Louisiana. The evaluations of
both knowledge and perception were also compared to determine if a relationship exists
between these two factors.
This study had the following objectives:
1. To describe adult residents of Louisiana on the following demographic
characteristics:
a. age,
b. gender,
c. ethnic background,
d. location of residence (in a rural area, on a farm, in a town, in a city),
e. parish of residence,
f. occupation of the head of household,
g. highest level of education.
2. To determine the knowledge of the adult residents of Louisiana regarding the
following selected aspects of the agriculture industry:
a. animal science,
b. plant science,
c. environmental science,
d. food science.
3. To determine the perceptions of the agriculture industry among adult residents of
Louisiana.
4. To determine if a relationship exists between knowledge of selected aspects of the
agriculture industry (defined as animal science, plant science, environmental
science, policy, and processing) and perceptions of the agriculture industry among
adult residents of Louisiana.
5. To determine if a relationship exists between perceptions of the agriculture industry
and the following demographic characteristics of adult members of the general
public in Louisiana:
a. age,
b. gender,
c. ethnic background,
d. location of residence (in a rural area, on a farm, in a town, in a city),
e. parish of residence,
f. occupation of the head of household,
g. highest level of education
6. To compare the perceptions of the agriculture industry among adult residents of
Louisiana by whether or not the respondent had completed a college degree in an
agricultural field.
7. To compare the perceptions of the agriculture industry among adult residents of
Louisiana by whether or not the respondent had prior agricultural training
(defined as whether or not the respondent indicated that they enrolled or participated
in any agriculture course(s) during high school or college, such as
FFA, 4-H, or other activities).
8. To compare the perceptions of the agriculture industry among adult residents of
Louisiana by whether or not the respondent had prior agricultural experience
(defined as whether or not the respondent indicated that they are currently a
member of Louisiana Farm Bureau).
9. To determine if a model exists explaining a significant portion of the variance in
perceptions of the agricultural industry among adult members of the general public
in Louisiana from the following measures:
a. knowledge of adult residents of Louisiana regarding selected aspects of the
agricultural industry,
b. age,
c. gender,
d. ethnic background,
e. location of residence (in a rural area, on a farm, in a town, in a city),
f. parish of residence,
g. occupation of the head of household,
h. highest level of education
Summary of Methodology
The target population for this study was residents of the state of Louisiana. For the
purposes of this study, included were all adult individuals that were residents of the state
of Louisiana. This study residency was derived by the individual’s registration of
telephone service in their name at a residence in the state of Louisiana. The accessible
population was defined as the group of adult individuals in the defined target population
who had registered residential telephone numbers. The accessible population was 547
adult residents of Louisiana. The frame of the population was established by the current
residential phone listings registered in the state phone company databases.
The instrument utilized in this study was based on a questionnaire found during a
review of related literature. The instrument consisted of fifty-five questions. This
instrument consisted of three sections: demographic characteristics, agriculture knowledge,
and perception of agriculture. The knowledge and perception sections of this instrument
were adapted from a similar questionnaire utilized by Frick, et al. (1995b).
Data was collected using phone interview techniques. The data was collected in the
month of February in the year 2008. The surveys were conducted randomly over the
course of a week.
Summary of Major Findings
The major findings of this study are discussed by objective.
Objective One
This objective was to describe adult residents of Louisiana on selected demographic
characteristics.
Of the 547 participants in this study, there were more females (n=289, 52.8%) than
males (n= 258, 47.2%). With regard to age, the largest response was from the age group
of 60+ years of age (n= 199, 37.3%) while the age group with the smallest number of
respondents was the 18-29 years of age category (n= 37, 6.9%). The majority of the
respondents stated that their ethnic background was “Caucasian” (n= 387, 70.7%) while
the ethnic background of African-American (n= 143, 26.1%) represented the second most
frequent response.
The largest group of respondents (n= 142, 26.3%) indicated their highest level of
education completed as “College Graduate- Non Agriculture”. Only four (.7%) of the
respondents indicated their highest level of education completed as “Post Graduate-
Agriculture or Related”, making this group the smallest response group to this item.
More of the respondents considered themselves to be the Head of Household (n= 338,
61.8%) than those who did not consider themselves to be the Head of Household (n= 209,
38.2%). A majority of the respondents were classified in the occupation of the head of
their household as “Laborer” (n= 262, 50.7%). Those who classified the occupation of the
head of their household to be “Other” (n= 13, 2.5%) were the smallest group of
respondents.
Logistically, the greatest number (n= 64, 11.7%) of respondents stated that their
parish of residence was East Baton Rouge while seven other parishes only recorded one
respondent (.001%) per parish. When grouped regionally, the area with the greatest
number of respondents was Acadiana (n= 181, 33.1%) while the area with the smallest
number of respondents was Orleans (n= 46, 8.4%). The majority of respondents (n= 235,
43.4%) stated that they lived in what they considered to be the “In a City”. Additionally,
the smallest group (n= 23, 4.2%) indicated that they considered their location of residence
to be “On a Farm”.
Objective Two
This objective was to determine the knowledge of the adult residents of Louisiana
regarding the agriculture industry. Participants were asked to answer true or false to
twenty statements. The statement that was responded to correctly by the largest number of
respondents was the statement “Hamburger is made from the meat of pigs” (n= 506,
2.5%). The statement that received the smallest number of correct responses was the
statement “Homogenizing kills bacteria in mild with heat” (n=116, 21.2%). The
researcher computed a knowledge score for each participant in the study by coding each
correct response as “1” and each incorrect response as “0”. These calculated scores
ranged from a low of 5 to a high of 20. These scores were averaged for the group and
the overall mean agriculture knowledge scores of adult residents of Louisiana was
13.60 (SD= 2.743).
The scale was further analyzed utilizing five of the seven predetermined areas of
agricultural knowledge proposed in previous research. The five categories were
environmental science, plant science, animal science, policy, and processing. Four
questions were assigned to each subscale with one question from each of the
predetermined areas overlapping into a sixth subscale associated with the state of
Louisiana. A subscale score was computed for each of the six subscales, defined as the
total number of correct responses in that subscale. The computed subscale scores
revealed that the respondents had the highest level of knowledge in the subscale of
environmental science (m= 3.07, SD= .959) and the lowest reported level of knowledge in
the subscale of processing (m= 2.51, SD= .828).
Objective Three
This objective was to determine the perceptions of the agriculture industry among
adult residents of Louisiana. Participants were asked to respond to twenty questions in
order to indicate their level of agreement or disagreement using a five-point Likert-Type
scale. The researcher designed an interpretive scale in order to interpret the response
items. The statement with the highest level of agreement was “Not all land is suitable for
farming” (m= 4.16, SD= 1.002) and was classified in the “agree” category. The statement
with the highest level of disagreement was “Farmers earn too much money” (m= 1.61,
SD= .898) and was classified in the “disagree” category.
Several statements were designed such that a “disagree” response indicated a more
positive perception of agriculture. The researcher reversed the scale on these items prior
to the identification of subscales. Four subscales were identified to be underlying
constructs of the perceptions of agriculture. The four factor model explained 35.24% of
the total explained variance. The four subscales included “Attitude Toward Farming”,
“Issues Relating to Food Supply”, “Farming Practices”, and “Food Prices”. The
researcher computed a subscale score for each of the constructs that are defined as the
mean of the items included in each respective subscale. The computed mean scores for
the various factors ranged from a high of 3.81 for the factor titled “Attitude Toward
Farming” to a low value of 3.14 for the factor labeled “Food Prices”.
Objective Four
This objective was to determine if a relationship exists between knowledge of selected
aspects of the agriculture industry and perceptions of the agriculture industry among adult
residents of Louisiana. Pearson’s Product Moment Correlations were calculated to
determine the direction and strength of this relationship. Davis’ (1971) descriptors were also
used to describe these correlations.
The highest relationship between the knowledge subscale “Policy” and the perception
subscales was with the perception subscale “Issues Relating to Food Supply” (r= .21,
p<.001). This relationship was such that higher levels of knowledge regarding
“Policy” were associated with more positive perceptions regarding “Issues Relating to
Food Supply”. The highest relationship between the knowledge subscale “Environmental
Science” and the perception subscales was with the perception subscale “Issues Relating to
Food Supply” (r= .23, p<.001). This was a “Low Association” based on Davis’ (1971)
descriptors. The relationship was such that higher levels of knowledge regarding
“Environmental Science” were associated with more positive perceptions of agriculture.
The highest relationship between the knowledge subscale “Plant Science” and the
perception subscale scores was found to be with the “Issues Relating to Food Supply”
subscale (r= .20, p<.001). The highest relationship found between the knowledge
subscale “Animal Science” and the perception subscale scores was with the “Issues
Relating to Food Supply” subscale (r= .12, p=.01). The most significant relationship
found between the knowledge subscale “Processing” and the perception subscales was the
perception subscale “Issues Relating to Food Supply” (r= .09, p= .03). In examination of
the relationship between the knowledge subscale “Louisiana” and the perception subscale
scores, the most significant relationship was found with the perception subscale “Food
Prices” (r= .17, p=<.001).
Each of these significant relationships was positive and such that higher levels in the
knowledge subscales were associated with a more positive perception of agriculture.
Objective Five
This objective was to determine if relationships exist between perceptions of the
agriculture industry and selected demographic characteristics of adult residents of Louisiana.
Mean scores previously identified in each of the subscales were utilized in examining these
relationships.
When examining the relationship between perceptions of agriculture and the
demographic characteristic age, two perception subscales scores were found to be
significantly related. The highest association identified was with the “Food Prices” subscale
(r= .16, p<.001) and was associated as a “Low Association”. This association was such that
respondents who were older tended to have more positive perceptions of agriculture on
“Food Prices”. The other significantly correlated subscale was with the “Issues Relating to
Food Supply” (r= -.12, p= .004) and was classified as a “Low Association”. The nature of
this relationship was such that younger respondents tended to have higher perceptions
related to the “Issues Relating to Food Supply” subscale. Results from the t-test that
examined the relationship between gender and perception of agriculture revealed a
significant difference in the subscales “Attitude Toward Farming”, “Issues Dealing with
Food Supply”, and “Farming Practices” all at p=<.001, and “Food Prices” at p= .049. The
nature of all of these differences were such that male respondents tended to have more
positive perceptions of agriculture on the subscales “Attitude Toward Farming”, “Issues
Dealing with Food Supply”, “Farming Practices”, and “Food Prices”.
In examining the relationship between the perceptions of agriculture and the variable
ethnic background, two ethnic groups were utilized. These included African
American and Caucasian. The ethnic groups of Hispanic, Asian, Native American, and
Other were not included in this measurement due to the small number of respondents in
each of these categories (Hispanic, n=8; Native American, n=7; Asian, n=1; Other, n=1).
The Leven’s Test for Equality of Variance revealed that the ethnic groups of African
American and Caucasian had significantly different variances for two of the perception
subscales “Attitude Toward Farming” (F= 4.078, p= .044) and “Farming Practices” (F=
9.682, p= .002). The t-test results showed significant differences between the two ethnic
groups and all of the perception subscales. The greatest significant difference was found in
the perception subscale “Attitude Toward Farming”. The differences were such that those
indicating that their ethnic background was Caucasian tended to have more positive
perceptions of agriculture than those who indicated their ethnic background to be African-
American.
Examination of the relationship between perceptions of agriculture and the variable
“Location of Residence” revealed one significant difference on the perception subscale
“Food Prices” (F= 2.961, p= .032). Although the Analysis of Variance test showed a
significant F value, when Tukey’s Post Hoc test was applied to the data no significant
differences were found.
When examining the relationship between perceptions of agriculture and the variable
“Parish of Residence”, the parishes indicated by the respondents were grouped into
geographic regions. This was done due to the insufficient number of respondents in all
parishes needed for individual parish comparisons. No significant differences were found
among the four geographic regions in Louisiana.
Examination of the relationship between perceptions of agriculture and the
demographic variable “Occupation of Head of Household”, the occupations were grouped
into four categories. These categories included “Laborer”, “Sales/ Clerical/ Technical”,
“Administrative/ Professional”, and “Other”. A significant difference was found among
the occupation groups on the perception subscale “Attitude Toward
Farming” (F= 4.122, p= .007). Tukey’s Post Hoc test revealed that the group “Laborer”
(M= 3.69, SD= .8257) was significantly different from the “Sales/ Clerical/ Technical”
group (M= 3.89, SD= .6591) and the “Professional/ Administrative” (M= 4.03, SD= .6625)
group.
In order to examine the relationship between perceptions of the agriculture industry
and the demographic variable “Highest Level of Education” the researcher used a one
way analysis of variance test. This test found two significant F values in the perception
subscales of “Attitude Toward Farming” (F= 3.475, p= .002) and “Food
Prices” (F= 2.176, p= .044). With regard to the perception subscale “Attitude Toward
Farming”, Tukey’s Post Hoc test revealed significant differences between the educational
level “Less than High School” (M= 3..40, SD= .8996) and three other educational levels
including “Some College” (M= 3.84, SD= .6275), “College Graduate- Non Agriculture” (M=
3.91, .6650), and “Post Graduate- Non Agriculture” (M= 3.91, SD= .6859). With regard to
the perception subscale “Food Prices”, although the analysis of variance test showed a
significant F value, the Tukey’s Post Hoc test found no significant differences
Objective Six
This objective was to compare the perceptions of the agriculture industry among adult
residents of Louisiana by whether or not the respondent had completed a college degree in
an agriculture or related field. The respondents indicated that 18 (3.3%) had received a
college degree in an agriculture or related field while the remaining 523 (95.6%) had not.
Of the respondents who stated that they had received a college degree in an agriculture or
related field, 14 (2.6%) obtained an undergraduate degree while four (.7%) obtained a
graduate level degree.
When the perception subscales were compared by whether or not they completed a
college degree in agriculture or related degree, no significant differences were found in
any of the subscales.
Objective Seven
This objective was to compare the perceptions of the agriculture industry among adult
residents of Louisiana by whether or not the respondent had prior agricultural training. This
training was defined as whether or not the respondent indicated that they enrolled or
participated in any agriculture course(s) during high school or college, such as FFA, 4-H, or
other activities. Of the 547 who responded, 322 respondents stated that they did not have
prior agricultural training while 225 respondents stated that they had received prior
agricultural training.
Each of the four perception subscales was compared by the independent variable. No
significant differences were revealed in the perception subscales scores between those with
prior training and those that did not have this type of training.
Objective Eight
This objective was to compare the perceptions of the agriculture industry among adult
residents of Louisiana by whether or not the respondent had prior agriculture experience.
This experience is defined as whether or not the respondent indicated that they are
currently a member of Louisiana Farm Bureau. Of the five hundred and forty respondents
to this item of the survey, 56 (10.0%) respondents indicated that they were currently
members of Louisiana Farm Bureau while 484 (90.0%) of the respondent group stated that
they were not currently members of Louisiana Farm Bureau.
Each of the four perception subscale scores was compared by the two levels of the
independent variable. A t-test was used due to the dichotomous nature of the independent
variable. These tests revealed two significant differences in the perception subscales
“Issues Relating to Food Supply” (t= 2.350, p= .019) and “Food Prices” (t= 2.306, p=
.022). These differences were such that respondents who had prior agriculture experience
(current membership in Louisiana Farm Bureau) tended to have more positive
perceptions of agriculture in the subscales areas of “Issues Relating to Food Supply” and
“Food Prices”.
Objective Nine
This objective was to determine if a model exists explaining a significant portion
of the variance in perceptions of the agriculture industry among adult residents of
Louisiana from selected measures. These measures included knowledge of adult residents
of Louisiana, age, gender, ethnic background, location of residence (in a rural area, on a
farm, in a town, in a city), parish of residence, occupation of the head of household, and
highest level of education. Dependent variables consisted of the perception subscales
determined previously by factor analysis. This objective was accomplished by using a
multiple regression analysis. The mean score for each of the perception subscales was
based on the information from the items lading into each subscale. The selected
demographic variables and knowledge subscale scores were used as independent variables
in the analysis and were entered into the analysis using stepwise entry. The variables that
were nominal or ordinal were recoded to make all of the variables dichotomous in nature.
Each dependent variable was examined for the presence of multicollinearity among the
independent variables in the analysis. This was accomplished through examination of the
tolerance values and the variance inflation factor (VIF) for the data included in the
analysis. All tolerance values were within the acceptable range above the .10 threshold.
The first dependent variable to be analyzed in this portion of the study was the perception
subscale “Attitude Toward Farming”. The independent variable “Knowledge Subscale-
Environmental Science” explained 5.3% (F change= 29.690, p= .001) of the variance in the
perception subscale. When the remaining variables were entered into the analysis, the
variable “Ethnic Background- Caucasian” explained 3.4% (F change=
19.432, p= <.001) of the variance, the variable “Gender” explained 1.4% (F change=
8.166, p= .004) of the variance, and the variable “Occupation of the Head of Household-
Sales/ Clerical/ Technical” explained 1.3% (F change= 7.583, p= .006). Combined, these
six variables explained 13.1% of the variance in the perception subscale “Attitude Toward
Farming”.
The nature of the influence of these variables was such that respondents with higher
subscale scores in the knowledge subscale “Environmental Science”, denoted their ethnic
background to be “Caucasian”, stated their head of household’s occupation to be in the
category of “Sales/ Clerical/ Technical”, or indicated their gender to be “Male” all tended
to have higher perception subscale scores relating to “Attitude Toward Farming”.
Additionally, those indicating their parish of residence to be within the “Orleans” region
or their highest educational level received as “High School Graduate” tended to have a
lower subscale scores in the perception subscale “Attitude Toward Farming”.
The second dependent variable to be analyzed in this portion of the study was the
perception subscale “Issues Relating to Food Supply”. The independent variable
“Knowledge Subscale- Environmental Science” entered into the analysis and explained
5.5% (F change= 30.594, p= <.001) of the variance in the perception subscale score
“Issues Relating to Food Supply”. When the remaining variables were entered into the
analysis, the variables “Gender- Female” explained 3.4% (F change= 19.737, p= <.001) of
the variance, “Knowledge Subscale- Policy” explained 1.5% (F change= 8.941, p=
.003) of the variance, and the variable “Ethnic Background- Caucasian” explained 1.4% (F
change= 8.941, p= .003). Combined, these six variables explained 13.1% of the variance
in the perception subscale “Issues Relating to Food Supply”.
The nature of the influence of these variables that entered the model was such that
respondents with higher subscale scores in the knowledge subscale area “Environmental
Science” or “Policy”, denoted their ethnic background to be “Caucasian”, denoted their
gender to be “Male”, or stated their parish of residence to be in the “Acadiana” region tended
to have higher subscale scores in the perception subscale “Issues Relating to Food Supply”.
Additionally, those respondents who denoted their highest educational level received to be
“High School Graduate” tended to have lower subscale scores in the perception subscale
“Issues Relating to Food Supply”.
The third dependent variable to be analyzed in this portion of the study was the
perception subscale “Farming Practices”. The variable “Gender- Female” entered the
analysis and explained 3.6% (F change = 19.894, p= <.001) of the variance in the
perception subscale score “Farming Practices”. When the remaining variables were
entered into the analysis, the variable “Ethnic Background- Caucasian” explained 1.9% (F
change = 10.732, p = .001) of the variance, and the variable “Knowledge Subscale-
Environmental Science” explained 1.4% (F change = 7.795, p = .005). Combined these
three variables explained 6.9% of the variance in the perception subscale “Farming
Practices”.
The nature of the influence of these variables that entered the model was such that
respondents with a higher subscale score in the knowledge area of “Environmental
Science”, or denoted their Gender to be “Male”, or denoted their ethnic background to be
“Caucasian” tended to have higher subscale scores in the perception subscale “Farming
Practices”.
The fourth dependent variable to be analyzed in this portion of the study was the
perception subscale “Food Prices”. The variable “Knowledge Subscale- Louisiana” entered
the analysis and explained 3.3% (F change = 17.915, p= <.001) of the variance in the
perception subscale score “Food Prices”. When the remaining variables were entered into the
analysis, the variable “Age” explained 2.8% (F change = 15.600, p = <.001) of the variance,
the variable “Location of Residence- In a Rural Area” explained 1.5% (F change = 8.613, p =
.003), and the variable “Gender” explained 1.3% (F change = 7.332, p = .007) of the variance
in the perception subscale score “Food Prices”. The last two items entered the analysis
explaining less than 1.0% of the variance. “Educational LevelPost Graduate- Non
Agriculture” explained 0.8% (F change = 4.772, p = .029) of the variance while “Location of
Residence-In a City” explained 0.8% (F change = 4.664, p =
.031) of the variance in the perception subscale. Combined these six variables explained
10.5% of the variance in the perception subscale “Food Prices”.
The nature of the influence of these variables that entered the model was such that
respondents with higher subscale scores in the knowledge areas of “Louisiana”, were older
in age, denoted their Gender to be “Male”, or denoted their highest level of education to be
“Post Graduate- Non Agriculture” tended to have higher subscale scores in the perception
subscale “Food Prices”. Those respondents who indicated that they considered their
location of residence to be “In a Rural Area” or “In a City” tended to have lower subscale
scores in the perception subscale “Food Prices”.
Conclusions, Implications, and Recommendations
Conclusion One
Adult members of the general public of Louisiana have a moderately high level of
knowledge with regard to agriculture. This conclusion is based on the overall mean
agriculture knowledge score of adult residents of Louisiana for the twenty items included in
the survey instrument equaling 13.60 (SD = 2.743) out of 20, or 68% of the knowledge items
were answered correctly.
These findings were similar to the results found by Frick, et al. (1995b) that surveyed
456 adults from rural areas and 428 adults from urban areas and asked 35 knowledge based
questions. The mean knowledge score for the respondents from rural areas was 24.25
(69.3%) while the mean knowledge score for the respondents from urban areas was 24.69
(70.5%). This similarity is also seen in the results found by Frick, et al. (1995a) who
surveyed 550 4-H members asking 35 knowledge-based questions. This research found
their mean knowledge score to be 23.07 (65.9%).
These findings are different from the findings of the study by Frick, et al. (1995c)
who surveyed 668 rural high school students and 453 urban inner-city high school
students. The overall knowledge score for both of these groups combined was 56%.
Although these two groups only included high school students, the mean knowledge scores
for each of these groups was below the mean knowledge score that was found in this study.
The findings of this study are also different from a similar study by Wright, Stewart, and
Birkenholz (1994) that reported knowledge scores for 435 eighth grade students, 164
enrolled in agriculture and 371 not enrolled in agriculture. The mean knowledge scores for
each of these groups was18.08 (52.6%) which was lower than the mean found by the
researcher.
Implications of this conclusion include efforts in educating the public, such as Ag
in the Classroom and commodity promotional materials, may have been successful in
increasing the knowledge levels of adult residents. The knowledge level found in the
adult population of Louisiana shows that the members of this group have a strong base for
developing further their knowledge levels.
Based on this conclusion, the researcher recommends continuation and expansion in
agriculture education efforts. Mass media promotion utilizing billboards, television ads,
newspaper articles, and web postings should be continued and increased. Additionally,
the researcher recommends that the use of “YouTube”, blog sites, and group networking
sites such as “Twitter” should be utilized in order to expand the population reached by
such efforts.
The researcher further recommends increasing publication of classroom agriculture
education materials designed to reach various audiences. Materials developed and
distributed by the Ag in the Classroom program are an example of such publications. The
researcher also recommends that commodity promotion boards continue to revamp
current educational publications as well as increase publication of classroom educational
materials for all commodities. One example of such a publication is the material
produced by the Rice Promotion Board in 2009. It is also recommended that the Ag in
the Classroom program expand to in-service teachers and distribute materials to educators
at the school level.
Conclusion Two
Adult residents of Louisiana have the highest levels of knowledge in the
Environmental Science area among the agricultural content areas addressed in this study.
The computed mean concept area scores revealed that adult members of the general public
of Louisiana reported the highest level of knowledge for the items in the “Environmental
Science” factor with a mean knowledge score of 3.07 (SD= .959) which fell into the
interpretive category of moderately high and was 76.8% of the items answered correctly.
These findings were similar to the results of the study by Frick, et al. (1995c) that
surveyed rural and inner-city high school students and rural and urban adult residents. The
study found Natural Resource knowledge scores, similar to the Environmental Science
knowledge concept area, to be higher than all other knowledge scores for concept areas.
The mean knowledge scores for the Natural Resources concept areas were 3.96 (79.2%)
and 3.90 (78.0%) in the study by Frick, et al. (1995c).
Implications of this conclusion are such that the high knowledge level seen in the
environmental science area is evidence that the general public of Louisiana is concerned
about the environment and its potential benefits. This is seen in the importance that the
general public has placed on the environment with the increased growth of programs such
as recycling, water conservation using household fixtures that use less water, and
decreased air emission programs. These programs are examples of the expanding
emphasis placed on the environmental sector. The increases in youth organizations
involvement in environmental projects such as the adopt-a-highway program are
increasing awareness while allowing individuals to become directly involved in
environmental issues. The increased exposure that the Louisiana coastline has been given
over the past five years has placed greater emphasis on the natural environment. This
exposure has given rise to interest in environmental changes and their role in the
increased risk of catastrophic events. The attention given to these areas has aided greatly
in the public relations aspect of increasing knowledge among the public with regard to
environmental issues.
The researcher recommends further research to determine adult resident’s
involvement in environmental activities such as participation in wildlife conservancies or
membership in wildlife habitat organizations such as Delta Waterfowl. This study should
also include exploratory research into the amount of time devoted to environmental
programs. This measurement should also determine extracurricular activities that include
some type of environmental connection, such as visits to state parks or conservatories such as
the Bluebonnet swamp in Baton Rouge.
The researcher also recommends an expanded study to measure the environmental
science concept area in more detail. For the purposes of the current study, each concept
area was limited to four questions. A more extensive study to measure knowledge of
environmental issues should include multiple questions on several areas associated with the
environment. Multiple questions on air quality, water quality, soil quality, urban impact,
agricultural impact, impact of industry, and conservation should be explored.
Due to the high level of knowledge reported in the environmental science area, the
researcher requests support of environmental organizations that assist in the continued
growth of this knowledge base such as the Sierra Club, Delta Waterfowl, and the
Nature Conservancy.
Conclusion Three
Adult members of the general public of Louisiana have more positive perceptions of
agriculture with regard to the “Attitude toward Farming” and “Issues Related to Food
Supply”. This conclusion is based on the mean perception scores of adult residents of
Louisiana for the perception concept areas being equal to 3.81 (SD= .73) and 3.72 (SD= .49),
respectively. These concept area scores were derived from the responses to the five items
included in each concept area of the survey.
These findings are similar to multiple studies on sustainable agriculture practices. Those
studies include results reported by Williams and Wise (1997) who surveyed 41 teachers
educating 464 eleventh and twelfth grade students involved in agriculture education on their
perceived impact of sustainable agriculture practices. The results showed a composite mean
across all items listed in the survey to be 3.82 (SD= .39). A similar study by Williams
(2000) surveyed 386 eleventh and twelfth grade student enrolled in agriculture education on
their expected impact from sustainable agriculture.
The mean across all items utilized in this survey was found to be 3.42. A study by
Gammon and Scofield (1998) also showed composite means for “younger” and “potential”
agricultural producers to be 3.49 (SD= .45) and 3.65 (SD= .44) respectively with regard to
the perceived results of sustainable agriculture practices. This data was collected over a
four year period from participants on the campus of Iowa State
University during the winter program and included 188 respondents.
The findings of the current study, however, differ from results reported by Frick,
et al. (1995c). Low perception totals were observed for rural and urban adults and rural
and urban high school students. The total perception scores for these four demographic
groups range from 73.97 (SD= 12.97) or 42.2% to 85.79 (SD= 15.42) or 49.0%. These
reported perception scores are lower than those seen in the current study and show a
lower level of perception of agriculture among rural and urban adults and high school
students than the level of perception of agriculture of adult residents in Louisiana.
The implications of this study are different for the two sets of perception of
agriculture concept areas. The perception concept areas “Attitude toward Farming” and
“Issues Related to Food Supply” are more positive in nature. The production of our food
and fiber and the activity that provides the public these goods are thought of as a
necessity. Necessities are held in higher regard than luxuries and for this reason it can be
reasoned that perception scale attitudes toward farming and the activities included in this
process are more positive.
The ability to purchase food and have it readily available for the public’s consumption
can be taken for granted. In recent years the general public of Louisiana has dealt with
multiple natural disasters that have altered the ability to transport, refrigerate, and
produce these goods. Many of the retail food chains were empty for weeks following the
fall hurricanes of 2008 and 2005. The general public was able to realize the importance
of their food supply. This reality, coupled with the ongoing publicity for world hunger
brings food supply to the forefront. We have seen the faces of starving children, the
helicopters delivering airdropped food supplies, and the advertisements here to sponsor
starving children around the world. This type of media attention to food supply, and lack
thereof, could be an explanation of why the food supply subscale is more positive.
The perception concept areas “Farming Practices” and “Food Prices” are both
ambivalent in nature. It can be reasoned that individuals are always questioning prices of
any purchase that is made, food purchases being no exception. With the economic issues
that we have seen on the cost of production, processing, transportation, and on the final
cost of the product purchases are made with caution due to the rising costs. For this reason
it is expected that the perception of the “Food Prices” concept area would not be
considered less positive. Similarly, it is to be expected that the perception of agriculture
concept area “Farming Practices” would also be interpreted as being less positive.
Negative media influences can play a huge role in the perception of the general public.
Headlines that highlight soil erosion due to runoff, application of harmful chemicals, and
use of large amounts of ground water are only a few of the headlines that the general public
may witness. For this reason, the use of best management practices is constantly
questioned.
The researcher recommends that all agriculture producers make deliberate efforts to
be in compliance with rules and regulations governing farming practices. Initiatives such
as the LSU AgCenter’s Master Farmer Program should be encouraged and supported by
the Louisiana legislature. Support for this program via correspondence to local legislators
is encouraged.
The researcher also recommends that Louisiana Farm Bureau and the LSU AgCenter
continue and expand positive media messages giving factual information regarding
farming practices. Support of programming including “This Week in Louisiana
Agriculture” should be encouraged. Short web based video clips depicting factual
agriculture information should be expanded and made more readily available to the
general public. Piazza (2009) states that information presented on the LSU AgCenter’s
website spans gender, geographic location, and age. This portal could potentially impact
nearly every citizen in the state of Louisiana. This portal, as well as those of other
agricultural organizations, should be maintained to include factual information on all
aspects of agriculture.
Similarly, the researcher encourages the promotion of “agritourism” endeavors.
Agritourism allows members of the general public to visit farms and ranches which
increases their knowledge and allows individual perceptions to be made. These perceptions
are void of the influences placed by negative and misleading media. The researcher also
encourages the protection of those individuals engaged in coordination of agritourism. It
has been suggested in prior research (Wright, et al, 1994) that positive perceptions are a
prerequisite to the development of good policy decisions related to agriculture. Louisiana
law 9:2795.5., passed in 2008, limits the liability of producers involved in agritourism
activities. Support of legislation similar to this is encouraged and recommended.
Conclusion Four
Agricultural knowledge and perception of agriculture are related. This conclusion is
based upon the 17 significant correlations between the six knowledge concept areas and
the four perception concept areas. Each of these correlations was significant at the .05
level or higher.
These findings are similar to those of Frick, et al. (1995c) who concluded that more
positive perception s might result if the agriculture literacy level was enhanced. This
study surveyed 1121 high school students that were residents of both rural and inner-city
areas. This conclusion was based on the significantly higher knowledge scores for both
rural and inner-city students that were reflected in the higher perception scores reported
for both groups.
These findings are also similar to the relationship between knowledge and perception
reported by Wright, Stewart, and Birkenholz (1994). This study surveyed 435 eleventh
grade students that were either enrolled in agriculture education or not enrolled in
agriculture education. They reported a weak relationship between agriculture knowledge
and perceptions of agriculture (r= .174).
The implications of this study are such that an increase in agricultural knowledge
may result in a more positive increase in perceptions of agriculture. The more positive the
perception that an individual holds with regard to an issue, the more likely they are to
support that issue both socially and financially. For this reason, more positive perceptions
are also related to legislative support in times of hardship, economic downslides, and
catastrophic events. It has been stated in prior research that positive knowledge and
perceptions about agriculture are a prerequisite to the development of good policy
decisions (Wright, et al., 1994). This support could result in the minimization for
adversity surrounding decisions that are made governing all aspects of agriculture, from
production to marketing. This increase in knowledge and perception will also provide
individuals the basis upon which to feel secure. This security may lead to the willingness
of individuals to be open to new techniques in production, processing, and marketing of
agricultural goods.
Promotion by use of billboards, television ads, newspaper articles, and web postings
should be continued and increased. The use of new web based media outlets is also
encouraged due to their growing popularity.
Conclusion Five
Caucasians have more positive perceptions of agriculture than African Americans.
This conclusion is based on the significant differences between the two ethnic
background groups of Caucasian and African American with regard to the four perception
concept areas. These concept areas were derived from the twenty perception items
utilized in the study. The differences between the two ethnic background groups was
such that respondents indicating their ethnic background to be Caucasian tended to have
more positive perceptions of agriculture than those respondents who indicated their ethnic
background to be African-American.
These findings are similar to the results reported by Newsom-Stewart and Sutphin
(2000) who surveyed 925 tenth grade students in the state of New York. This study observed
ethnic differences in perceptions of agriculture between “white” or Caucasian students and all
other ethnic groups in six of the thirteen perception descriptors. These descriptors include
“importance to the economy”, “importance to the future”, “politically important”, “a place for
high school graduates to work”, “high tech”, and “a place for college graduates to work”.
This study also observed significant differences between white students and those of other
ethnic backgrounds in twelve of the thirteen perception descriptors utilized in this study.
These findings are also similar to the results by Mendoza (2006) who found that
respondents who indicated their race to be Caucasian were more willing to participate in
environmental programs as opposed to those respondents who indicated their race to be
African-American. It can be reasoned that individuals would likely not participate in
activities without positive outcomes. For this reason, willingness to learn is directly related
to positive perception.
The findings from the current study are also similar to the results reported by Frick, et
al. (1995b) who studied 668 rural high school students and 453 inner-city high school
students. The rural high school student group consisted of primarily white students
(88.5%) while the inner-city high school group consisted of primarily black students
(86.3%). The overall perception score was not significantly different and only two of the
seven perception scores for the concept areas were significantly different between the two
groups. Rural high school students received higher mean scores in both the “Plants” and
“Animals” concept area subscores.
Implications of this conclusion are such that the lower perceptions of agriculture
scores for the ethnic background group “African- American” show that more effort is
needed to influence perceptions of this demographic group. Given that the consumption of
food is the primary contact that many minorities have with agricultural sciences, many
minorities exhibit limited awareness of the science and business skills that are utilized in
this industry. Minimal advertising has been seen on television stations that target minority
populations that present the agriculture industry in a factual manner. This presentation is
needed to shift the “negative images of agriculture by minorities” toward one based on the
scientific and business dimensions of the agriculture industry. The low perception affects
recruitment into agriculture related education and employment fields. The resulting small
numbers of individuals involved in the agriculture industry are maintained by ongoing
perceptions that agriculture is an industry focused on vocational skills and one meant for
white males. (Wiley, et. al., 1997)
The researcher recommends targeted public relations that deliver positive messages or
presents the current traits of the field of agriculture accurately on television stations, in
magazines and printed materials, and via web postings that are frequented by individuals
with the ethnic background “African American”. The ability to communicate to all ethnic
groups the highly diverse and scientific nature of agriculture should become a priority.
Expansion of recruitment that targets members of the “African American”
population for both educational and occupational endeavors is highly recommended.
Efforts to include all demographic groups in agriculture fields would become a goal of all
individuals currently involved in the agriculture industry. Programs such as the Penn
State College of Agriculture Sciences “Food and Agricultural Sciences Workshop” (FAS)
should be adopted by other universities. This program consists of five days of instruction
taught by university faculty to expose academically talented minority students to non
vocational curricula and career opportunities in the agriculture sciences. Wiley, et al.
(1997) studied the effect of the FAS program on the perceptions of 44 students enrolled in
the program during the summer of 1994. The findings showed stability among the
participants’ attitudes before and up to a year post involvement in the FAS program. The
findings did show a positive shift in the posttest means in the areas that indicated
participants associated agricultural careers with more than production agriculture and held
a greater understanding about agricultural jobs. (Wiley, et. al., 1997)
The researcher recommends further research that includes a more detailed study to
measure the impact of ethnic background on the knowledge of agriculture concept areas.
A study that would examine correlations between ethnic background and knowledge
would expand the understanding of the correlations that are noted between several
knowledge and perception concept area scores in the current study.
Understanding the perception of minority groups with regard to agriculture would enable
this industry to educate this demographic in a more productive manner. This greater
understanding could allow education to be placed in concept areas that are in more need of
resources.
Conclusion Six
There is no difference in perceptions of agriculture between those adult residents of
Louisiana who have a college degree in an agriculture related field and those adult
residents of Louisiana who do not have a college degree in an agriculture related field.
This conclusion is based on the findings of the study that no significant differences
between the two groups were found in the four perception concept areas by whether or not
the respondents indicated that they had completed a college degree and that their degree
was in an agriculture related field. These concept area comparisons included:
“Food Prices” (t539 = 1.721, p = .086); “Farming Practices” (t539 = 0.865, p = .388);
“Issues Relating to Food Supply” t539 = -0.736, p = .462); and “Attitude toward
Farming” (t539 = -0.645, p = .519).
Results of the current study are in contrast to those reported by Brown and Stewart
(1993) when they examined 264 middle school students enrolled in an agriculture
curriculum. Brown and Stewart utilized a pre and post test design to examine the effects
of enrollment in an agriculture course on a student’s knowledge and attitude toward
agriculture. Their findings showed a change in the knowledge of and attitudes toward
agriculture after being enrolled in the course.
Several possible explanations exist for the findings regarding the lack of effects from
having received direct instruction in agriculture. One such explanation for the current
study’s outcome is the low number of participants that indicated they held a college degree
in agriculture or a related field. Eighteen respondents of the five hundred and forty seven
total respondents indicated that they obtained a college degree in an agriculture or related
field. This low number of respondents was too small to provide a valid comparison
between the two groups.
An additional explanation is evidence of the evolution that colleges of agriculture
have seen over time. A greater percentage of agriculture colleges contain degree programs
that are not considered to be traditional agriculture programs related to production
agriculture. Areas of study such as textile design, dietetics, workforce education,
landscape design, and environmental science are all examples of non traditional
agriculture programs. Although these areas of study are highly related to the agriculture
industry of today, they attract a more diverse group of individuals into their programs that
are more likely to have no agriculture background.
Due to this lack of agriculture background in students enrolled in agriculture one of
the growing responsibilities that agricultural educators face is to develop a positive
association with agriculture in the public sector (Perritt and Morton, 1990). The researcher
recommends continuation of universal agriculture programming that allows all students
(agriculture and non agriculture) to gain exposure to basic agriculture knowledge. Courses
such as the Agriculture 1001 taught at Louisiana State University are examples of general
agriculture courses that expose all participants to the broad range of agriculture areas and
the connection between these areas. Expansion of this type of program to include
information on basic areas of agriculture such as animal sciences, plant sciences, food
science, agricultural business, and environmental science is also recommended by the
researcher. This expansion provides a mode of delivery for the knowledge base needed to
change perceptions toward the positive.
Conclusion Seven
No differences in perception of agriculture were identified between those adult residents
of Louisiana who had prior agriculture training (defined as whether or not the respondent
indicated that they enrolled or participated in any agriculture courses such as FFA, 4-H, or
other agriculture activities) and those who did not have this type of prior agriculture
experience.
This conclusion is based on the lack of significant statistical differences between the
four perception subscale scores. These subscale comparisons included: “Food Prices” (t454
= -.746, p = .456); “Farming Practices” (t454 = -.841, p = .401); “Issues Relating to Food
Supply” t454 = -1.463, p = .144); and “Attitude Toward Farming” (t454 = -1.427, p = .154).
Results of the current study are different than those reported by Dyer, Lacey, and
Osborn (1996). Dyer, et al, surveyed 495 college of agriculture freshmen enrolled at the
University of Illinois during the academic year 1994-1995. These findings were such that
students who completed high school agriculture courses displayed different attitudes toward
the field of agriculture than students who were not high school agriculture program
participants. These two groups were significantly different on ten of the twenty one construct
areas. Overall, this study found that students who participated in high school agriculture
programs held a more positive attitude of agriculture with regard to agriculture as a career
field, high school agriculture programs, and university agriculture programs.
These findings were also in contrast to those found by Frick, et al. (1995a). Frick et al
reported that the overall mean perception score for 4-H members was high. The perception
score in the this study was increased by the demographic characteristic “enrolled in high
school agriculture education” and showed positive relationship to the perception scores
with an F value of 7.74.
Possible explanations exist for the findings regarding the effects from having
participated in 4-H, FFA, or other agriculture activities. One explanation is that the lack
of differences in perception between those with prior agriculture experience and those
with no prior agriculture experience are a potential cause of the evolution of the 4-H and
FFA Programs. The evolution of these programs has allowed the inclusion of
nontraditional instruction that was geared more toward professional and personal
development of the membership. Although this diversification has increased the diversity
of the membership and the ability to reach the interests of more of the population, the
small level of mandated instruction on traditional agriculture skills within the FFA and 4H
programs has also had an effect on the level of perception scores. The placement of both
4-H and FFA in the school setting could also be a reason for this evolution due to these
programs having to justify their existence with purpose measurable in a similar manner to
all other curricula.
The researcher recommends the continued inclusion of traditional agriculture skill
training. This training provides participants hands on agriculture activities that they are able
to base their perceptions upon. The marriage of both traditional training and the non-
traditional training that encourages personal development are also recommended.
Conclusion Eight
Differences were identified in perceptions of agriculture for respondents with prior
agricultural experience (defined as whether or not the respondent indicated that they are
currently a member of Louisiana Farm Bureau) and the perceptions of agriculture for
those respondents who did not have prior agricultural experience (defined as whether or
not the respondent indicated that they are currently a member of Louisiana Farm Bureau).
This conclusion is based on the findings of the study that significant differences
were found in two perception subscale areas by whether or not the respondent indicated
that they were currently a member of Louisiana Farm Bureau. The significant differences
found were in the perception of agriculture concept areas “Issues Relating to Food Supply”
(t538 = 2.350, p = .019) and “Food Prices” (t538 = 2.306, p = .022).
To date, no prior research on the effect that membership in a general farming
organization such as Farm Bureau has on the perception of agriculture of adults has not
been conducted. Mission statements of various state Farm Bureau organizations include the
Enhancement of the public perception of agriculture (Texas Farm Bureau, 2009) and the
desire to communicate to and inform individuals and organizations that influence
perceptions of agriculture (Kansas Farm Bureau, 2009)
One possible explanation for the differences in perceptions of agriculture could be
farm bureau members’ involvement in production agriculture. Membership in Farm
Bureau is usually acquired in two ways; as a pre-requisite to obtaining insurance through the
subsidiary company, or by requesting outright membership due to interest in protecting the
rights and lifestyles of farm and rural Americans. Most individuals only realize that they are
“members” of the Farm Bureau organization if they obtain membership in the second manner
due to their vested interest in the actions of the organization. For this reason, it can be
reasoned that those who have vested interest in production agriculture would be the same
individuals who declared membership in Farm Bureau.
Individuals that are involved in production agriculture would have more positive
perceptions of agriculture in both perception concept areas; “Issues Relating to Food
Supply” and “Food Prices”. The more positive perceptions of agriculture are due to their
involvement in or close relationship to the production of food. The knowledge that they
have with regard to the production safeguards, amount of labor needed for food production,
and knowledge of world commodity prices gives farm bureau members the ability to derive
a more fact based perception.
The researcher recommends increased promotion of agriculture to members of the
general public. Information on production agriculture that would allow members of the
general public the ability to base perceptions upon need to be placed into mass media
markets.
The researcher also recommends increased promotion to the membership that is not
actively engaged or related to production agriculture but holds membership in Farm
Bureau. Depiction of this group and information targeted directly toward them would
allow information to be delivered to an already captive audience due to their link to the
organization via the insurance sector of the Farm Bureau. This type of education is
encouraged and recommended.
