Baseline Sensitivity To Demethylation Inhibitors Fungicides In Cercospora Spp. And Corynespora Spp. In Arkansas Soybeans, Evan Buckner, Alejandro Rojas

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

Cercospora spp. and Corynespora spp. are two common foliar fungal pathogens in Arkansas and other soybean-producing areas. Two primary diseases caused by Cercospora spp. are Cercospora Leaf Blight (CLB, caused mainly by C. kikuchii) and Frogeye Leaf Spot (C. sojina). Over time, many fungicides used to combat these diseases have become ineffective as the pathogens have developed a resistance to them. The class of the fungicide in question is Triazoles [Demethylation Inhibitors (DMI)–FRAC 3]. Fifteen isolates consisting of Corynespora cassiicola, Cercospora sojina, and Cercospora flagellaris were tested to determine baseline sensitivities using serial dilutions (0, 0.01, 1, 10, 50 mg/L) …

Willingness-To-Pay For Halal And Branded Poultry In Northern Mozambique, Alison J. Creasey, L. Lanier Nalley

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

While price typically drives consumers’ food-purchasing decisions in low-income countries, religious attributes associated with food production and corporate branding could influence buying patterns. In Mozambique, more than 46% of people were living below the poverty line of ($0.31 USD) per day in 2018. That being said, in the Nampula Province (the location of this study), which is the second poorest province in the country, over 25% of the population is Muslim and may be willing-to-pay (WTP) a premium for Halal meat products to uphold Islamic beliefs. Like many parts of sub-Saharan Africa, poultry is the fastest-growing source of protein. Since …

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 …

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 …

Impact Of Selected Infrared Wavelengths On Inactivation Of Microbes On Rough Rice, Rebecca L. Bowie, Griffiths Atungulu, Abass Oduola, Shantae Wilson, Zeinab Mohammadi-Shad

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

Formation of harmful microbes and their associated mycotoxins on rough rice during storage presents negative socioeconomic impacts to producers and consumers. The objective for this study was to investigate the impact of treating rough rice with selected infrared (IR) wavelengths at different IR intensities and heating durations, followed by a tempering step for further inactivation of microbes (mold and bacteria) on the grain. Freshly-harvested long-grain, hybrid, rough rice (XL 745) with initial moisture content (IMC) of 18.4% wet basis (w.b.) was used. Two-hundred grams (200 g) samples of rice were treated at different IR wavelengths (λ), 3.2, 4.5, and 5.8 …

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 …
