Graduate Theses and Dissertations

This study uses the 2016 Irrigation Survey from Arkansas, Louisiana, and Mississippi to document the use of irrigation best management practices (IBMPs), analyze use patterns, and use quantitative methods to determine factors that influence producers’ decisions regarding IBMPs. IBMPs included in the survey can be grouped as: field management practices (zero-grade leveling, precision-grade leveling, end blocking, warped surface, and deep tillage), water flow control practices (computerized pipe-hole selection, multiple-inlet irrigation, surge irrigation, alternate wetting and drying, cutback irrigation, flow meters, and pump timers), water recovery/storage practices (tail-water recovery system and on-farm storage reservoir), and advanced irrigation scheduling practices (soil moisture …


Precise Nitrogen Recommendations Improve Economic And Environmental Outcomes In Arkansas Rice Production, Cristin Roberts Dec 2021

Precise Nitrogen Recommendations Improve Economic And Environmental Outcomes In Arkansas Rice Production, Cristin Roberts

Graduate Theses and Dissertations

Soil testing has become an increasingly important tool in making agronomically efficient production management decisions. N-STaR is a N test used in rice production and is unique in its ability to selectively quantify soil organic-N compounds which are readily mineralizable for plant N uptake and contribute to growth and yield. This study uses historical (2002–2018) adoption rates of N-STaR, which is funded through Rice Checkoff funds, to calculate the total cost savings from N-STaR adoption. These cost savings alone would be the “typical” benefits used in a benefit-cost ratio of a public ally funded research program like N-STaR. However, we …

The Influence Of Peer Irrigators On The Extensive And Intensive Margin Of Irrigation Techniques, Victoria Bailey May 2021

The Influence Of Peer Irrigators On The Extensive And Intensive Margin Of Irrigation Techniques, Victoria Bailey

Graduate Theses and Dissertations

We examine how irrigation techniques in use by family and friends influence the use and share of land utilizing different irrigation techniques by Arkansas producers. A bivariate sample selection model simultaneously estimates how farm characteristics determine the use and explain the share of a farm that utilizes an irrigation technique. We find that the irrigation techniques in use by family and friends do affect the irrigation techniques a producer uses and the share of acres utilizing different irrigation techniques. A producer with a family or friend that uses end-blocking irrigation is 41% more likely to use end-blocking themselves. Having a …


Quality Determinates Of Rice Price In Open Bag Markets In Sub-Saharan Africa, Bailey Peterson-Wilhelm May 2021

Quality Determinates Of Rice Price In Open Bag Markets In Sub-Saharan Africa, Bailey Peterson-Wilhelm

Graduate Theses and Dissertations

Weaknesses in the grades and standards system in low-income countries across Sub-Saharan Africa undermine the transparency of agricultural markets. In the Democratic Republic of the Congo (DRC), Ghana and Mozambique rice is predominately sold in open bags and if rice price does not reflect its quality, then inefficiencies may lead to consumer welfare losses. Importantly, it is possible that impoverished communities are priced out of the market due to inflated and inefficient prices. The objective of this study is to examine determinates of rice price by estimating the impact of selected rice quality attributes on rice prices in DRC, Ghana …

The Effects Of Common Stressors On Poultry Production: A Case Study In Northern Mozambique, Grace Lehfeldt May 2021

The Effects Of Common Stressors On Poultry Production: A Case Study In Northern Mozambique, Grace Lehfeldt

Finance Undergraduate Honors Theses

Chicken is one of the main proteins that feeds the world. For centuries, the human race has relied on chickens to eat. Therefore, as food science becomes more relevant, the way that chickens are raised has become a science. However, this is not true in every part of the world. In Mozambique the process for raising chickens for consumption is not the same as it would be in America. This is a study of two specific “stressors” (feed and temperature) and how they impacted chicken growth and development on a live production poultry farm in Northern Mozambique. In addition, it …

Description Of Job Embeddedness In Arkansas County Extension Agents, Anika Parks May 2021

Description Of Job Embeddedness In Arkansas County Extension Agents, Anika Parks

Graduate Theses and Dissertations

The Cooperative Extension System (CES) has had a long-standing problem with the retention of its county Extension agents (CEAs), who are in charge of running various programs in over 3,000 counties within the United States. When a CEA leaves a county, voluntarily or involuntarily, the community members are left without that leader, and their needs go unmet, which was proposed to increase voluntary turnover among CEAs even further. Arkansas CES has had its problems with turnover, and studying this issue through the lens of Job Embeddedness Theory was identified as a gap in the literature.

Job Embeddedness Theory is a …

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 …


Asymmetric Exchange Rate Pass-Through In Southeast Asian Rice Trade, Taylor Wiseman May 2020

Asymmetric Exchange Rate Pass-Through In Southeast Asian Rice Trade, Taylor Wiseman

Graduate Theses and Dissertations

Asian countries consume approximately 90% of the world’s rice supply. Between 2007 and 2014, Thailand, Vietnam, and India accounted for 60% of the world’s exports of rice. This paper estimates the impact of exchange rate fluctuations on bilateral trade flows in Southeast Asia. Because most Southeast Asian countries have state trading enterprises or agencies controlling rice trade, this analysis will provide insight as to whether these agencies respond to exchange rate fluctuations in a manner consistent with economic theory. Behavior inconsistent with economic theory could provide evidence of stabilizing domestic prices, market power, or export expansion policies. The analysis focuses …


The Economics Of On-Farm Rice Drying In Arkansas, Clayton Parker May 2020

The Economics Of On-Farm Rice Drying In Arkansas, Clayton Parker

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Globally, rice producers are faced with the temporal problem of deciding the optimal time to being rice harvest. When harvested, paddy rice is typically at a moisture content (HMC) between 15 and 22%. Upon delivery, the rice is 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 in price/unit as the MC of grain decreases from a range of +22% to 13.5%. This study estimates an alternative linear relationship in the stair-step model to determine MC …

Use Of Acetolactate Synthase-Inhibiting Herbicides In Inzen Grain Sorghum (Sorghum Bicolor L. Moench Ssp. Bicolor), Hunter Bowman

Graduate Theses and Dissertations

Grain sorghum is typically grown as a rotational crop in Arkansas because of its many benefits, one being the effective control of Palmer amaranth through the use of atrazine. However, limited options exist for postemergence (POST) control of weedy grasses within the crop. Inzen™ grain sorghum is the result of a nicosulfuron resistant weedy sorghum biotype cross-bred with a commercial line of grain sorghum. Inzen™ allows for safe use of over-the-top applications of nicosulfuron within the crop. Nicosulfuron is an acetolactate synthase (ALS)-inhibiting herbicide, which has historically been used in corn for control of weedy grasses. Experiments were conducted in …
