Comparing detailed production costs and input use across countries allows producers to see if they are competitive with similar operations in other countries. This thesis looks at the cost efficiency of a sample of corn and soybean farms representing 16 countries to understand efficiency and cost trends at the farm-level, compare these farms, and identify factors that might explain farm-level performance. This analysis delves into detailed production data to calculate an important international benchmark, which is currently not available. ^ The data consist of a six-year (2008-2013) unbalanced panel of 35 corn-producing farms and 16 soybean-producing farms, which come from …

The Effect Of Biochar On The Growth Of Agricultural Weed Species, Karen Anne Mitchell

Open Access Theses

Biochar, a carbon-rich residue similar to charcoal, has been proposed as a soil amendment to improve soil quality and increase crop yields while simultaneously mitigating climate change by the sequestration of carbon. The beneficial effect of biochar on crops may extend to weed species and, although it is well known that weeds reduce crop yields, there is little published research on the effect of biochar on agricultural weed species. In a series of greenhouse and growth chamber experiments, three questions were addressed. First, how does nitrogen interact with biochar produced from a single feedstock to affect weeds? Second, how do …

Assessing The Spatial Variability Of Soils In Uganda, Joshua Okach Minai

Open Access Theses

Uganda's soils were once considered the most fertile in Africa, but soil erosion and soil nutrient mining have led to soil degradation and declining agricultural productivity. Lack of environmental awareness among farmers, traditional agricultural practices, minimal inorganic fertilizer use, and little to no use of improved crop varieties all contribute to continued soil degradation. The objectives of this study were: (1) to characterize the spatial distribution of selected physical and chemical soil properties in Uganda on a national scale utilizing the data collected by Nkonya et al. (2008), and (2) to identify the major factors and processes that are dominant …

Stages Of Succession Planning And Factors Of Transferring Management And Ownership For The Family Agribusiness, Ryan D. Musselman

Open Access Theses

Although many family business owners want to maintain family control of the business for future generations, few businesses survive across generations. Neglecting to plan an entry and exit strategy for family members are just two factors that explains why more businesses don't succeed in transferring the business to the next generation in the family. Ordered Probit models and Probit models were used to discover factors that influence the process of family business transfer of management and ownership. Data came from a survey of 736 businesses in four Midwest states. ^ Four factors were found to be correlated with the transition …

Are Cover Crops Worth It? It Depends, Joshua S. Leirer

Open Access Theses

Society is becoming increasingly more aware of the environmental consequences of agricultural production. Farmers today are under increasing pressure to adopt more sustainable farm management practices. One method to improve the sustainability of crop production is the use of cover crops. Cover crops are planted "off-season" to provide agronomic and environmental benefits. The objective of this research is to quantify the impacts of cover crops and determine where and under which management practices cover crops provide the greatest benefit. Management practices include different crop rotations, tillage practices and residue removal rates. This paper will focus on soil erosion, nitrate leaching …

Tracking Sales Activities In Agribusiness, Jiayu Li

Open Access Theses

Decisions in the sales area, including customer and product selection and margin discipline, shape profits for companies in agribusiness. Management of the sales function takes place at the organizational, managerial, and practitioner level, each of which requires data about the process. Individual salespeople benefit from better knowledge of customers (Dixon & Adamson, 2011), and sales managers benefit from understanding the activities of salespeople. Organizationally, data on sales activities may be used to determine progress toward organizational goals or to compensate salespeople. ^ This research utilized surveys to investigate how agribusiness companies differ in the ways they keep track of sales …

Male And Female Interaction In Apple: Pollen Tube Growth, Fruit Set, Fruit Quality, And Return Bloom, Khalil Rahman Jahed

Open Access Theses

In apple, adequate and appropriate pollination and fertilization is required for fruit set, fruit quality and subsequent fruit growth. Pollen source, pollen-style interaction and compatibility, and ample pollen tube growth are potentially highly influential factors on the fertilization and fruit setting process. Pollinizer is considered to be one of the influential factors and has a remarkable impact on fertilization. However, basic information on the level of pollinizer compatibility and its contribution to yield is lacking for many commercial apple cultivars. Hence, we conducted these experiments to compare pollinizers in terms of pollen tube growth, fruit set, fruit quality and return …

Does A Family-First Philosophy Affect Family Business Profitability? An Analysis Of Family Businesses In The Midwest, Maria Victoria Iglesias

This study also investigates how the distribution of the business to the next generation, as well as how hiring family members who may not have the qualifications …

Communication, Home Bias And Social Capital, Sharon Raszap Skorbiansky

Open Access Dissertations

This dissertation consists of three essays on the effects of communication, home bias and social capital. The first study analyzes three different laboratory treatments that determine if policies that introduce and improve communication are beneficial to a market. The control treatment has no communication. Then, two different types of communication mechanisms are introduced: cheap communication, where subjects are able to lie, and truthful communication, where only honest messages may be sent. The results demonstrate that truthful communication dramatically improves subjects' ability to trade efficiently, ultimately leading to higher social surplus and lower income inequalities. Cheap communication does not produce the …

Propionate Induces Gluconeogenesis In Dairy Cattle Through Direct Activation Of The Bovine Cytosolic Phosphoenolpyruvate Carboxykinase Gene Promoter, Qian Zhang

Open Access Dissertations

Phosphoenolpyruvate carboxykinase (PCK, GTP; EC4.1.1.32) catalyzes the conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP), a critical reaction for gluconeogenesis. The two isoforms of PCK, namely cytosolic PCK (PCK1), and the mitochondrial PCK (PCK2) are abundantly expressed in liver and kidney. Increased PCK1 activity and mRNA expression in liver is observed as feed intake recovers during early lactation in dairy cows, a condition linked to increased ruminal propionate production. The central hypothesis of this dissertation is that propionate regulates its own metabolism in liver of dairy cattle through regulation of the PCK1 gene. The objectives of this dissertation were to determine: …

Modeling, Empirics And Policy Implications Of Firm Heterogeneity In International Trade, Zeynep Akgul

Open Access Dissertations

Computable General Equilibrium (CGE) models are essential computational tools for trade policy analysis. While traditional CGE models based on the Armington assumption of national product differentiation have been successfully applied to various policy scenarios, they also have significant limitations in explaining the firm-level information prevalent in the recent international trade literature. The pioneering work of Melitz (2003) has provided a firm heterogeneity theory that can help address the shortcomings of Armington-based CGE models by introducing additional productivity mechanisms and extensive margin effects. Incorporation of firm heterogeneity in mainstream CGE models offers great potential to improve computational policy analysis. Even though …

Evaluating Animal Agriculture Impacts On Water Quality: Data Gaps In West Central Minnesota Case Study, Ed Brands

Environmental Studies Publications

Balancing the economic and food system contributions of animal agriculture with negative impacts such as water quality degradation has been a recurring question in Minnesota and other agricultural states (e.g., Iowa and North Carolina). Over the past 15 years significant federal- and state-level changes in the regulation of animal feeding operations (AFOs) and associated practices have attempted to improve water quality. The impacts of these changes are unclear; therefore, the main purpose of this project was to evaluate policies designed to protect water quality from manure runoff and spills within the context of a manageable geographic area. Project work was …

Soil Total Organic Carbon And Farmers’ Perceptions Associated With Bokashi Application In Cerro Punta, Panama, Emma Searson

Independent Study Project (ISP) Collection

Sustainable use and maintenance of agricultural soils are important for maintaining long-term agricultural productivity and environmental quality. These issues are especially important in Cerro Punta, known as the breadbasket of Panama, which is experiencing severe erosion. While current practices and agrochemical usage damage soil health and function over time, application of organic material improves soil physic-chemical properties such as nutrient and total organic carbon (TOC) content. Bokashi, a fermented organic soil amendment with effective microorganisms (EM), is thought to be especially beneficial due to its ability to augment populations of soil microbes, which deliver plant-available nutrients to crops and improve …
