Wheat is important to South African food security; due to the significant drop in wheat area planted since the abolishment of …


Profitability Analysis Of Varying Herd Sizes Based On Price Signals In Cow-Calf Operations, Colson Tester Dec 2017

Profitability Analysis Of Varying Herd Sizes Based On Price Signals In Cow-Calf Operations, Colson Tester

Agricultural Economics and Agribusiness Undergraduate Honors Theses

The third most consumed meat around the world is beef. Despite global growth in demand, cattle markets experience price cycles related to biological production lags causing variability in cash flow and profitability for producers. Price-driven herd size management strategies thus have received attention. This study adds to that literature by analyzing both price and production risk using three herd size management strategies: i) steady state – holding herd size constant; ii) dollar cost averaging – keeping reinvestment constant by varying the number of replacement heifers retained at a constant long run average dollar total; and iii) moving average – using …


Modelling The Impact Of National Development Strategies For The East African Rice Sector, Florence Muthee Dec 2017

Modelling The Impact Of National Development Strategies For The East African Rice Sector, Florence Muthee

In The Field The Women Saved The Crop: The Women’S Land Army Of World War Ii, Denna M. Clymer

Graduate Theses and Dissertations

The Women’s Land Army brought together rural and urban sectors of the United States in a climate of national and regional crisis. By the time the country was cast into war, the agricultural sector was already caught in a downward economic spiral that drove away laborers. With demand falling, and farms propped up only by experiments in subsidy and parity, when military and industrial jobs emerged in urban areas, farm laborers became scarce. At the same time the war created jobs for men outside of the agricultural sector, farm prices recovered and demand soared, forcing farmers to look to women …

Qualitative Analysis Of Social Capital In Arkansas – A Case Study Based Approach, Valerie Kilders Aug 2017

Qualitative Analysis Of Social Capital In Arkansas – A Case Study Based Approach, Valerie Kilders

Graduate Theses and Dissertations

Despite the vast research on social capital in general, only very little research is focused on the quality of social capital. While some research studies incorporated aspects that are associated with the quality of social capital, they often take a one dimensional approach that fails to take the different aspects of the topic into consideration. In order to gain more insights into this I conducted a series of semi-structured interviews in three rural counties in Arkansas. The counties were selected on the basis of a social capital index of all U.S. counties using quantitative measures. I used a guide on …

Evaluating The Impact Of An All-Vegetable Protein Supplement Containing Fat Emulsifiers And Probiotics On Broiler Performance, Jordan Weil Aug 2017

Evaluating The Impact Of An All-Vegetable Protein Supplement Containing Fat Emulsifiers And Probiotics On Broiler Performance, Jordan Weil

Graduate Theses and Dissertations

Currently, several niche markets, such as organic and “all natural”, are marketed within the poultry industry. However, little research has been undertaken to determine the cost-effectiveness of poultry diets used to produce chicken within these markets. Specifically, the economics and resulting profits associated with raising chicken with antibiotic-free, all-vegetable (AV) diets are not evaluated. As national chain restaurants such as Chick-fil-A and Panera Bread begin to mandate poultry suppliers raise chicken without antibiotics and use AV diets, it becomes increasingly important to evaluate the economics for integrators. Given the rapidly changing feeding strategies necessary to respond to consumers’ and wholesalers’ …


The Bracero Program In The Arkansas Delta: The Power Held By Planter Elite, William Chase Whittington Aug 2017

The Bracero Program In The Arkansas Delta: The Power Held By Planter Elite, William Chase Whittington

Graduate Theses and Dissertations

This paper examines the Bracero Program and its implementation from the start of World War II to the end of the program in 1964. Farmers and planters in America needed a sufficient labor supply once the war started, and Mexico became the main supplier. The Bracero Program was initiated as a war effort and meant to only last until the end of the war, but the planter elite had far different intentions once they realized how productive and inexpensive the program could be. This paper identifies the leading causes for how the Bracero Program was able to last over twenty …


The Cost Of Forward Contracting In Mississippi River Barge Freight And Cif Nola Markets, Bradley John Isbell Aug 2017

The Cost Of Forward Contracting In Mississippi River Barge Freight And Cif Nola Markets, Bradley John Isbell

Graduate Theses and Dissertations

Grain elevators often use paper markets to mitigate the risk of (or hedge) their cash grain positions, as well as establish a profit margin through basis trading. Typically, merchandisers use futures or forward contracts to perform these transactions. However, in order to liquidate a cash grain position, grain transportation must be arranged in order to deliver the grain to the buyer. For elevators located along the Mississippi River system selling to Gulf export elevators in New Orleans, that mode of grain transportation is most likely river barge. Contracts for barges are bought and sold by grain merchants either directly with …

Developing Sustainable Rice Production Through Image Classification, Parker R. Fitzgerald May 2017

Developing Sustainable Rice Production Through Image Classification, Parker R. Fitzgerald

Industrial Engineering Undergraduate Honors Theses

The agricultural industry’s continued success is critical to our future. However, many agricultural practices—specifically rice farming—are currently based on unsustainable methods. The processes used in rice farming consume water at an unsupportable rate, and, consequently, are serious contributors to rising emission levels. Several alternative growing methods have been introduced, and one of the most promising candidates is Alternative Wetting and Drying (AWD). An obstacle encountered by proponents of these methods comes in implementation. Studies have shown AWD is more successful in fields with higher leveling precision. The research in this study works to create a stepping stone for farmers to …

Refusing To Be Dispossessed: African American Land Retention In The Us South From Reconstruction To World War Ii, Camille Goldmon

Graduate Theses and Dissertations

African Americans in the South were tied to the land during slavery and after emancipation. Many felt that land ownership was the key to freedom. For decades, black farmers strove for land ownership, in many cases falling prey to sharecropping and tenancy agreements in the meantime. Despite this drive toward independent farming, however, since 1920, there has been a steady decline in the number of black farm owners. This trend is especially prevalent in the Southern United States. The black farm owners who persevered through periods of economic, social, and political turmoil were able to, for varying reasons, navigate those …
