The DYD’s goal is to incentivize healthy eating among individuals of low income and promote spending at farmers markets. Food insecurity affects over 60,000 individuals in Washington and Benton counties in Arkansas. The aim of this study was to assess how the DYD program impacted users’ food accessibility and how the program could be improved for the future. A survey was used to address basic demographics, type, …

The Biofiltration Ability Of Asparagus Densiflorus To Remove Sulfur Dioxide From The Indoor Atmosphere, Rhiannon De La Rosa, Mary Savin

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Sulfur dioxide is an inorganic compound (IC) and air pollutant that causes health risks in humans. The buildup of sulfur dioxide (SO2) in enclosed indoor spaces is, therefore, a concern to human health, especially since the average person spends 90% of his/her time indoors. This study focused on decreasing SO2 concentration in a cost-effective and simple way—by using botanical biofiltration, or the uptake of pollutants by plants. Research in biofiltration has focused mostly on the remediation of volatile organic compounds (VOC). However, research has also shown that plant species that remediate VOC efficiently also have the potential for efficient IC …

The Economics Of On-Farm Rice Drying In Arkansas, Clayton J. Parker, Lanier Nalley

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Globally, rice producers are faced with the temporal problem of deciding the optimal time to harvest rice. When harvested, paddy rice is typically at a harvest moisture content (HMC) between 15% and 22% and subsequently dried by the mill to a moisture content (MC) of 12.5%. Riceland Foods Inc., the largest miller of rice in the world, uses a stair-step pricing model to charge farmers to dry, which can complicate the timing of harvest as producers try to balance the tradeoff of minimizing drying costs by waiting to harvest at lower HMC vs. maintaining higher rice quality typically observed when …

The Impact Of Income On Nutrition: A Case Study Of Northern Mozambique, Hunter Swanigan, Lawton Lanier Nalley

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

In 2017, Mozambique ranked as one of the least developed countries in the world by measures of health, education, and income. With a minimal annual income, purchasing adequate food to meet recommended levels of nutrients for a healthy diet is difficult, leaving 40% of the country undernourished. This study analyzed what foods are available during the dry months (hungry season) of May through October in the Nampula province of Mozambique to determine if it is possible to meet recommended levels of nutrients from purchasing and growing food. Three different levels of income were used to determine what percentage of the …

The Political Preference Of Arkansas Farmers And Ranchers, Rachel J. Barry, Donna L. Graham

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Access to information is critical to improving production efficiency, but little is known about how farmers are informed on the policy or issues influencing programs related to farming. This research sought to determine the sources of communication used by farmers and ranchers to form opinions about agricultural policy and candidates, identify the issues important in voting, and their level of participation in the political process. Face-to-face interaction was the preferred form of communication in farm organization meetings, with friends, or farm agencies. Magazines were the preferred source of print communication, and university/extension websites were preferred for internet sources. Broadcast media …

Drivers Of On-Farm Performance Of Irrigation Water Management Practices: Empirical Evidence From Eastern Arkansas, Jacob Askey

Biological and Agricultural Engineering Undergraduate Honors Theses

Unsustainable agricultural practices are putting a strain on freshwater supplies in many parts of the world. More efficient irrigation techniques are going to be critical to feed a growing population. Data from the 2016 Arkansas Irrigation Survey was used to assess the adoption of three Irrigation Water Management (IWM) practices: multiple inlet rice irrigation, tailwater recovery, and storage reservoirs. Results indicate that these practices do not always lead to reported pumping time reductions, a proxy for water use savings. Large variations in pumping time reduction are observed across producers for all three practices. A Tobit model was used to examine …

Assessing The Economic Viability Of Arkansas Farms Under The 2018 Farm Bill, Grant Wilson

Graduate Theses and Dissertations

For over a century, the American agricultural industry has relied on federal government support to aid in the maintenance and expansion of farming operations. Since 1933, a series of 18 farm bills have shaped agricultural policy into what is commonly known as the agricultural safety net. The 2018 farm bill was passed on December 20, 2018 and is the most recent update of the agricultural safety net. Commodity programs and federal crop insurance are two key components of today’s agricultural safety net, and many times, these programs may be the difference between a net loss and a positive net income …

Estimating Demand Elasticities For Rice In Benin, Ogoudele Simon Codjo

Graduate Theses and Dissertations

Rice consumption in Benin is increasing along with shifting consumer demand toward higher quality rice. In this context of changing demands, experimental estimation methods provide an effective way to estimate the current state of consumer preferences. We conducted a hypothetical choice experiment in 15 open markets in Benin to analyze the demand for rice and its substitutes. The results reveal that consumers value quality rice, even those in the low-income class. While high income consumers are more likely to choose high quality imported rice, low- and middle-income consumers are more likely to select high quality domestic rice among the set …

Poultry Labeling: Knowledge, Perceptions, And Preferences Among Adolescents, Eleni L. Parsons

Graduate Theses and Dissertations

The purpose of this study was to determine the knowledge, perceptions, and preferences of adolescents in regard to the labeling of poultry products. The theory of planned behavior (TPB) and Elaboration Likelihood Model (ELM) were used to display the relationship of perceptions, attitude, and behavior intentions. Quantitative data was collected in a descriptive research design. The population included youth, aged 14 – 18 years, involved in the Arkansas 4-H State O’Rama competition (N = 400). The sample (n = 80) ensured a 90% confidence interval of the population. Data was collected by administering paper surveys that addressed four product labels …

Essays In Microeconomics, Teng Ma

Graduate Theses and Dissertations

This dissertation consists of three essays of different topics in microeconomics.

Chapter 1 investigates the effect of environmental uncertainty over the issue of resource allocation in a common pool resources setting. This chapter provides a model of how agents allocate resource among abatement technology, production, and saving with an endogenously determined uncertain damage. The results of a laboratory experiment show a negative effect of uncertain damage on abatement technology adoption and a non-linear relationship between the investment in abatement technology and the self reported risk aversion. Contrary to the “common belief” that greater risk averse agents invest more in abatement …

Agricultural Economics and Agribusiness Undergraduate Honors Theses

The primary goal of this research is to access the feasibility of implementing and operating small scale aquaponic systems in a home setting to serve as a means of producing high quality fresh produce and fish protein to supplement similar store-bought products. Factors such as system cost, skill level and management requirements will be addressed alongside customizable, educational and sustainable aspects of aquaponic systems to determine whether home aquaponic systems are a feasible option for the home grower. To elaborate, feasibility in this research will refer to both economic costs relative to costs of the system. Outlined in this short …

The Effect Of Labeling Information Framing On Genetically Modified Food Choices: A Query Theory Account, Taylor Pruitt

Agricultural Economics and Agribusiness Undergraduate Honors Theses

The progression of policy that regulates genetically modified (GM) food in the US is a prime example of how the role of the government reformulates in relation to societal changes. Support for various labeling programs is formed around key themes which center on the benefits and costs associated with GM labels. The goal of this experiment was to explore the effect of information framing on GM food choices. This was accomplished by presenting information for or against GM labeling in terms of the benefits (positive framing) or costs (negative framing) to consumers. 1,410 consumers participated in an economic experiment where …

The Farmers’ Federation: Regional Racial Mythologies As Agricultural Capital, Jama Mcmurtery Grove

Graduate Theses and Dissertations

In 1927, the Farmers’ Federation agricultural cooperative in Western North Carolina launched an organization to solicit funds from wealthy donors. The money raised through philanthropic campaigns enabled the cooperative to fund large-scale agricultural projects, which helped members navigate the dramatic agricultural transformations of the early twentieth century. Although the cooperative advocated a progressive program of business-minded, scientific farming, its leadership modified programs to reflect farmer members’ limited resources and the realities of mountain production. As a result, the co-op provided a crucial bridge between white farmers and new methods of agricultural production that reached deep into peoples’ familial and productive …

Evaluation Of Herd Size Management Strategies, Colson A. Tester

Graduate Theses and Dissertations

This thesis is comprised of two studies examining the effects of price signal based herd size management strategies on profitability of cow-calf operations. Herd size management strategies were evaluated across the previous two cattle cycles, 1990-2014, using a fixed land resource and included a variety of production scenarios. These scenarios varied in terms of stocking rates, fertilizer applications rates, and calving season. Each scenario was also analyzed both with and without weather effects on forage production. Weather effects were simulated using a production index derived from satellite imagery across the observed 25-year period. Three herd size management strategies: i) constant …

Comprehensive Poultry Supply Chain Model With Vertical And Horizontal Linkages: Implication Of Domestic And International Shocks, Hakan Unveren

Graduate Theses and Dissertations

According to USDA FAS, in 2017, the US was the largest broiler-producing country with 18.696 million metric tons and the second largest exporter of broiler products with 3.075 million metric tons (Brazil is the largest exporter with 3.847 million metric tons). Thus, around 83% of US production is consumed domestically. According to USITC, chickens are the most important protein source in the US, and Americans consume more chicken per capita than any other country. However, while the broiler industry is a key segment of US agriculture, it is underserved by large-scale supply-chain and trade models.

In this study, to fill …

Implications Of Rice Cultivar Selection To Optimize Returns From Crop Insurance, David Ethan Branscum

Graduate Theses and Dissertations

Rice production differs from most other field crops by distinct differences in yields across cultivars and rice producers being paid for yield after post-harvest milling. Using eleven years (2003-2013) of Arkansas harvest data from performance trials in six different locations, hybrids have 19% higher paddy yields and head rice yield rate 1.7% lower than conventional cultivars. Given the 2014 Farm Bill’s emphasis on crop insurance as a risk management tool for producers, these variations in yield among cultivars have significant implications for rice producers. Comparing national level, crop insurance data on corn, soybeans and rice indicates rice producers strongly prefer …

Optimization Of The Light Environment For Broiler Chickens, Douglas J. Aldridge

Graduate Theses and Dissertations

The use of artificial light sources has been necessitated by the use of fully enclosed rearing facilities for improved environmental control. Light Emitting Diodes (LED) have been developed as a light source that reduce the utilities required to provide equal light to that of incandescent sources. The following reports were carried out to investigate the effects of two light color temperatures, light intensity and light intensity gradients on broiler chicken production and behavior. The first investigation consisting of two consecutive trials investigated the effect of two light color temperatures (2700 K and 5000 K) in addition to the preference for …

Taking advantage of inherent natural systems, aquaponic practices hold the potential to serve as an educational, sustainable, and profitable hobby for home gardeners facing common constraints such as temperature, space, and pests. The goal of this research was to assess the feasibility of implementing a small scale (4,542-liter) home -based aquaponic system in a small (48.768 square meter) greenhouse to produce fresh produce and fish protein. System construction and maintenance costs were compared to the value of crops and fish produced to determine whether this aquaponic system is a feasible option for the home grower. It was hypothesized that this …

Determination Of Optimum Harvest Date For Winter Malting Quality Barley In Northwest Arkansas, Paul Wolf, David Moon, Richard Esten Mason

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Due to the strict quality requirements, only 10% of worldwide barley is used for malting, though malting quality barley comes with a price increase of up to 50% or greater. With the craft brewery industry growing in Northwest Arkansas there is a growing demand for locally sourced malt quality barley. However, data are lacking regarding production practices for barley in Arkansas. The optimal harvest date for malting quality barley is at physiological maturity. This is because many of the malting traits (such as germination energy) decline as harvest is delayed, which make it difficult to meet the criteria for malting …

Identifying Arkansas Food Desert Blocks Suitable For A Peer-To-Peer Modeled Food Redistribution Program, Emily A. King, Jennie S. Popp, Michael R. Thomsen, Di Fang, Alvaro Durand-Morat

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Abstract

Nearly 10% of Americans reside in low-income urban food deserts which are low-income areas that lack access to affordable and nutritious foods. Food deserts in Arkansas contribute to a food insecurity rate above the national average, making it one of the most food insecure states in the country. Increased internet usage and consumer interest in sharing based companies contribute to the idea of a sharing, or peer-to-peer (P2P) style food redistribution program. The objective of this study is to identify which of the 186,211census blocks in the state of Arkansas are food deserts and best suited for and in …
