Willingness To Pay For Irrigation Water Under Scarcity Conditions, Tyler Robert Knapp
Willingness To Pay For Irrigation Water Under Scarcity Conditions, Tyler Robert Knapp
Graduate Theses and Dissertations
Reliance of Arkansas agricultural producers on groundwater for irrigation has led to depletion of the Mississippi River Valley alluvial aquifer. Without intervention, consequences include insufficient groundwater to meet irrigation demand as well as drawdown of the deeper Sparta Aquifer, upon which communities in eastern Arkansas rely for non-agricultural use. Among proposed solutions to combat groundwater decline is the construction of off-farm surface water infrastructure to meet the irrigation needs of producers. Despite the importance of irrigated agriculture to Arkansas, there is little know about the economic value of irrigation water to producers. Thus, we implement a double-bounded dichotomous choice contingent …

Query Theory Applications: Choice Experiments Under Oath, Attendance To Attributes, And Genetically Modified Food Labeling Policy, Nathan Paul Kemper
Query Theory Applications: Choice Experiments Under Oath, Attendance To Attributes, And Genetically Modified Food Labeling Policy, Nathan Paul Kemper
Graduate Theses and Dissertations
In recent years, there has been an intensifying campaign by some stakeholders regarding concern over genetically modified (GM) foods in the U.S. As a result, the issue of labeling has entered into the federal agenda. This research uses Query Theory to provide a deeper understanding of the demand for GM foods and the preferences for GM policy. Query theory is first applied to the formation of hypothetical bias in the estimation of consumers’ willingness-to-pay. To address this, the honesty oath is used as an ex-ante technique to reduce hypothetical bias.
Paper one using Query Theory in a discrete-choice experiment (DCE) …

The Impact Of Climate Change In Bangladesh On The Rice Market And Farm Households, Mst Ashrafun Nahar
The Impact Of Climate Change In Bangladesh On The Rice Market And Farm Households, Mst Ashrafun Nahar
Graduate Theses and Dissertations
Bangladesh is trying to achieve self-sufficiency in domestic rice production but climate change effects on agricultural production makes it challenging to attain the goal. The country is highly vulnerable to the effects of climate change since it is the major cause to rise in sea level, more warm summer, and happening food and cyclone in the country.
This study develops an Aggregate Farm Household Model to analyze the impact of potential land loss and yield reduction from climate change on production, consumption, prices, welfare, and the ability of government to achieve self-sufficiency in rice production. The model is calibrated to …
Evaluation Of Agricultural Policy In The Dairy Sector In Kosovo And Efficiency Analysis At The Farm Level, Egzon Bajrami
Evaluation Of Agricultural Policy In The Dairy Sector In Kosovo And Efficiency Analysis At The Farm Level, Egzon Bajrami
Graduate Theses and Dissertations
This thesis consists of two studies on the dairy sector in Kosovo. The first study evaluates the effect of the Subsidy per Head Scheme (SPHS) on increasing production, land use, gross income and number of dairy cows on dairy farms in Kosovo. Results from the Propensity Score Matching (PSM) approach using four alternative matching algorithms revealed that SPHS has not had any impact on increasing land use, gross income or the number of dairy cows per farm. Furthermore, SPHS had a negative impact on decreasing land use and number of cows for the participating dairy farmers in the program. In …
Experiences Of Agricultural Education Preservice Teachers Engaging In Critical Friendships, Sable Sellick
Experiences Of Agricultural Education Preservice Teachers Engaging In Critical Friendships, Sable Sellick
Graduate Theses and Dissertations
Like educators in other disciplines, agricultural education preservice teachers must find ways to improve as teachers using methods such as reflection or peer observation. Critical friendship combines both, promoting reflection through the use of a critical friend who observes an individual’s teaching and provides constructive criticism to help the individual advance their practice. This qualitative study sought to use the critical friendship concept to assist agricultural education preservice teachers in reflecting on their teaching techniques. Participants were randomly assigned to one of two groups; one group selected a critical friend in agricultural education, and the other group selected a critical …
The Impact Of Crop Insurance On Indonesian Rice Production, Zaura Fadhliani
The Impact Of Crop Insurance On Indonesian Rice Production, Zaura Fadhliani
Graduate Theses and Dissertations
This study builds a theoretical model of the yield-based MPCI crop insurance policy for a risk averse rice farmer in Indonesia and presents the comparative statics analysis of policy variables on yield through the coupling, wealth, and insurance effects. Moreover, Using yield data from 1979 to 2014 for the Tuban Regency, this study applies numerical optimization to the model and simulates the effects of different policies on input use, certainty equivalents, indemnity payment, and premiums. The theoretical analysis shows that no coupling effect exists for change in the coverage level, while a coupling effect exists for change in the subsidy …
Characterization Of Broiler Lines Divergently Selected For Breast Muscle Color, Sara Katherine Orlowski
Characterization Of Broiler Lines Divergently Selected For Breast Muscle Color, Sara Katherine Orlowski
Graduate Theses and Dissertations
An increase in the consumption of poultry has generated an increase in demand for higher yielding broilers. This has led to an increase in atypical meat and issues with appearance. Color is a direct result of a pH decline as meat goes through rigor mortis with meat generally becoming lighter. If the pH declines too rapidly or too slowly, meat quality can suffer. Physical properties of meat can be altered by pH. A fast pH decline results in pale meat with decreased tenderness. A slow pH decline can result in darker meat with a reduced shelf-life. With a known relationship …
Eucalyptus In Kenya; Impacts On Environment And Society, Brandy M. Garrett Kluthe
Eucalyptus In Kenya; Impacts On Environment And Society, Brandy M. Garrett Kluthe
Graduate Theses and Dissertations
Eucalyptus trees were introduced to Kenya a little over a century ago. European colonization along with the development of a railway system increased the demand for a fast growing wood source. The expansion of the tree across the fertile lands in Kenya raises concerns about the environmental impact on ecosystems where it has been introduced. These concerns include degraded soils, loss of water resources, co-introduction of ectomycorrhizal species, and allelopathy. Economic benefits to local landowners were also explored as well as the potential for large Eucalyptus woodlots to maximize the sequestration of CO₂ from the atmosphere. This was examined through …
Nutritional Deficiencies During The Harvest Season According To Household Consumption And Level Of Nutritional Knowledge: A Case Study Of Northern Mozambique, Maggie Jo Hansen
Nutritional Deficiencies During The Harvest Season According To Household Consumption And Level Of Nutritional Knowledge: A Case Study Of Northern Mozambique, Maggie Jo Hansen
Graduate Theses and Dissertations
Mozambique is classified as a low income country, the lowest development classification defined by the World Bank. It is underdeveloped in food security, agricultural production, and nutritional status, and research shows its residents are not foreign to poverty and malnutrition. Low protein, starchy foods (maize, rice, wheat, cassava) comprise the majority of the Mozambican diet; these starchy foods are the most available for consumption. Although availability impacts diet, educational barriers may also threaten the knowledge of nutrition and perceptions of healthy foods. Illiteracy and lack of education are extreme challenges to disseminating nutritional education efforts in the rural Nampula region. …
Consumer Willingness To Pay For Genetically Engineered Edamame, Elijah John Wolfe
Consumer Willingness To Pay For Genetically Engineered Edamame, Elijah John Wolfe
Graduate Theses and Dissertations
This study examined the effect of GM labeling on consumer willingness to pay (WTP) for edamame. It also investigated how people reacted to different messages and whether the order of receiving positive or negative information about GM technology impacted their willingness to pay (WTP). The study had three components: (1) a sensory test of GM and non-GM labeled products; (2) a non-hypothetical experimental auction to assess WTP for GM, non-GM and unlabeled products; and (3) a questionnaire to collect demographics and other information from the participants. Results of the sensory evaluation revealed no statistically significant difference between GM and non-GM …

The Production And Exportation Of Arkansas Non Gmo Vs Gmo Soybeans To China, Weston Cartwright
Supply Chain Management Undergraduate Honors Theses
In recent years, the increase and shift in China’s population combined with a reduction in useable farmland due to soil contamination has prompted a significant increase in food imports. Soybeans, in particular, have become a significant import, and the United States is one of their prime suppliers. Chinese soybean imports have increased from 18 million bushels in 1996 to 1.171 billion bushels in 2015. Soybeans are used in food products like tofu and cooking oils and also as a base for animal feed. In the United States, soybeans are the second largest field crop, ranking just behind corn. Close to …
Spread Trading In Corn Futures Market, Ryan D. Napier
Spread Trading In Corn Futures Market, Ryan D. Napier
Graduate Theses and Dissertations
The non-linear relationship between old crop – new crop year spreads in corn futures market and stock-to-use (S-U) ratios published by the United States Department of Agriculture is analyzed. Using a non-linear logarithmic smooth transition regression (LSTR) model, we capture asymmetric market behaviors in high and low S-U regimes. Capturing this relationship and understanding the non-linear aspects of the relationship is of interest of grain merchandizers and speculators in the market. A spread trading strategy is simulated for the sample period, January 1985 through April 2015, to determine if the non-linear relationship is a profitable arbitrage opportunity in the market.
Meat Quality And Sensory Analysis Of Broiler Breast Fillets With Woody Breast Muscle Myopathy, Jessica Solo
Meat Quality And Sensory Analysis Of Broiler Breast Fillets With Woody Breast Muscle Myopathy, Jessica Solo
Graduate Theses and Dissertations
Recently, the poultry industry has encountered an emerging muscle myopathy known as woody breast (WB), which is characterized by hardness throughout the Pectoralis major muscle. Two experiments were performed to assess sensory characteristics and acceptability of WB meat and to determine the effect of broiler age on meat quality factors in varying severities of WB. Fillets were categorized as normal (NORM), moderate (MOD), or severe (SEV) WB. In Experiment 1 (Exp. 1), descriptive (n=9 trained panelists) and consumer (n=74 panelists) sensory analysis was conducted with NORM and SEV fillets at hot and cold serving temperatures (HOTNORM, COLDNORM, HOTSEV, COLDSEV). In …
Calcium And Magnesium Absorption And Retention By Growing Goats Offered Diets With Different Calcium Sources., Jennifer Long
Calcium And Magnesium Absorption And Retention By Growing Goats Offered Diets With Different Calcium Sources., Jennifer Long
Animal Science Undergraduate Honors Theses
Calcium addition is necessary in order to balance the high phosphorus concentrations that are characteristic of high-concentrate ruminant diets. However, calcium sources differ in their bioavailability. Our objective was to determine apparent Ca and Mg absorption and retention in goats offered diets containing different sources of Ca. Spanish-Boer goats (n=18; 19.6 ± 1.88 kg) were stratified by BW and sex and randomized to dietary treatments consisting of Purina Antlermax 16 containing either calcium carbonate (CC), Calmin (CM) or Milk Cal (MC). Goats were adapted to a control, corn-based high-concentrate diet on pasture and then moved to individual 1.0 × 1.5 …

Using Precision Agriculture Field Data To Evaluate Combine Harvesting Efficiency, Justin H. Carroll, Don Johnson, Jeff Miller, Kristofor Brye
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Soybeans must be harvested during a limited time period using expensive combines and associated equipment. Maximizing combine field efficiency, the ratio of the actual harvesting capacity to theoretical harvesting capacity, is an important objective of machinery managers. Spatial and temporal yield data from a 2012 CaseIH 8120 Axial-Flow combine equipped with a 9 meter MacDon D-65 Draper header and the Case-IH Advanced Farming System (AFS) yield monitoring system were used to examine field efficiency when harvesting soybean in three Arkansas Delta irrigated soybean fields during the 2015 season. Time efficiencies (TE) in the three fields ranged from 72.9% to 85.8% …

Then And Now: Across Ten Years Of Arkansas Women In Agriculture, Paige Acklie, Jennie Popp, Donald Johnson, Tamara Walkingstick
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The United States Agricultural Census show that between 2002 and 2012, the number of women farm operators in Arkansas grew 14% (from 19,856 to 22,637). These women operators have made up an increasingly larger percentage of all farm operators in the state (from almost 29% to nearly 33%). There is little published information regarding changes over time in the role of women in agriculture, their challenges, and factors important to their success. While some surveys of farm women have been conducted, these surveys are generally insufficient because data exist only for one point in time. This research uses the first, …
