Hosting The Third Annual Young Women In Agriculture Career And Leadership Seminar, Emma E. Morris, Madyline J. Braught

Agricultural Education and Communication

Agriculture has traditionally been a male-dominated industry; however, recent years have shown a significant growth in female presence. Women are beginning to take leadership roles both on the farm and within advocacy, lobbying, and business entities in the industry. According to the latest agricultural census data from the United States Department of Agriculture (USDA), in 2012, women farmers controlled seven percent of the nation’s farmland (Census, 2014). Additionally, women held leadership roles in 14 percent of the nation’s two million farms (Census, 2014). This data is several years old, and likely the numbers have grown since the last ...


What’S At Steak? The Political Discourse Of Emissions Intensity And Implications Of Animal Agriculture, Kalyn Simon 2018 The University of San Francisco

What’S At Steak? The Political Discourse Of Emissions Intensity And Implications Of Animal Agriculture, Kalyn Simon

Master's Theses

This thesis analyzes the international discourse of greenhouse gas emissions in relation to livestock production. Specific government ministries, research institutes, and multilateral organizations are framing a new strategy to mitigate emissions by using emissions intensity metrics. Emissions intensity is a ratio comparing emissions produced per unit of animal product as oppose to measuring absolute emissions. This research is acknowledged as a win-win scenario which allows for a reduction of greenhouse gas emissions while continuing production more efficiently. This thesis outlines the emergence of this metric in international discourse and the implications this shift has on the livestock sector globally. Ultimately ...

Ecological And Economic Benefits Of Integrating Sheep Into Viticulture Production, Meredith T. Niles, Rachael Garrett, Drew Walsh 2018 The University of Vermont

Ecological And Economic Benefits Of Integrating Sheep Into Viticulture Production, Meredith T. Niles, Rachael Garrett, Drew Walsh

College of Agriculture and Life Sciences Faculty Publications

The integration of crop and livestock systems has been recognized for its potential to reduce the environmental impacts associated with agriculture and improve farmer livelihoods. However, to date, most research has focused on the integration of cattle into crop and pasture systems. Here we examine the integration of sheep into vineyards and assess farmers’ perceived benefits and costs of the practice. Viticulture expansion has led to significant land use change in recent years and new environmental challenges, particularly with respect to herbicide use. Sheep integration into vineyards offers the potential to utilize the synergies of both systems to reduce external ...


How Will The Section 199(A) Tax Deduction Affect Cooperatives?, Greg McKee 2018 University of Nebraska-Lincoln

How Will The Section 199(A) Tax Deduction Affect Cooperatives?, Greg Mckee

Cornhusker Economics

The design of the income tax code reflects the special role of patronage equity in cooperative finance. Federal tax laws and policies allow agricultural cooperatives to retain net income as a source of equity capital by giving special tax deductions when income is allocated to patrons in proportion to their business with the cooperative. Income distribution choices by cooperatives have tax consequences.

Characteristics Contributing To Nebraska Farm And Ranch Financial Stress, Kate Brooks, Cory Walters, Jay Parsons, Andrea Ramirez, Larry Van Tassell, Bradley D. Lubben, J. David Aiken

Cornhusker Economics

Significant financial changes have been underway in the U.S. agricultural system. After a decade of increases in crop and livestock prices mirrored by corresponding increases in expenses, prices began declining dramatically in 2014 (USDA-NASS, 2017). Figure 1 shows yearly net farm income for Nebraska crop and livestock producers from 2000 to 2015 (USDA, ERS). A survey in July 2016 indicated that 52 percent of Nebraska farmers and ranchers were financially stressed.

Sweet Sorghum As An Ethanol Feedstock In Western Nebraska – Could It Happen?, Richard Perrin, Lilyan Fulginiti, Subir Bairagi, Ismail Dweikat

Cornhusker Economics

It has been proposed that non-irrigated sweet sorghum might be grown in western Nebraska as a seasonal substitute for corn grain in corn ethanol plants. In the research summarized here, we examine the economic feasibility of this possibility, based on the technical data that are currently available about sweet sorghum production.


Practical Implications Of Erythromycin Resistance Gene Diversity On Surveillance And Monitoring Of Resistance, Elizabeth L. Rieke, Jinlyung Choi, Thomas B. Moorman, Michelle L. Soupir, Heather K. Allen, Schuyler D. Smith, Adina Howe 2018 Iowa State University

Practical Implications Of Erythromycin Resistance Gene Diversity On Surveillance And Monitoring Of Resistance, Elizabeth L. Rieke, Jinlyung Choi, Thomas B. Moorman, Michelle L. Soupir, Heather K. Allen, Schuyler D. Smith, Adina Howe

Agricultural and Biosystems Engineering Publications

Use of antibiotics in human and animal medicine has applied selective pressure for the global dissemination of antibiotic-resistant bacteria. Therefore, it is of interest to develop strategies to mitigate the continued amplification and transmission of resistance genes in environmental reservoirs such as farms, hospitals, and watersheds. However, the efficacy of mitigation strategies is difficult to evaluate because it is unclear which resistance genes are important to monitor, and which primers to use to detect those genes. Here we evaluated the diversity of one type of macrolide antibiotic resistance gene (erm) in one type of environment (manure) to determine which primers ...


Depolymerization Of Post-Consumer Polylactic Acid Products, David A. Grewell, Gowrishankar Srinivasan, Eric W. Cochran 2018 Iowa State University

Depolymerization Of Post-Consumer Polylactic Acid Products, David A. Grewell, Gowrishankar Srinivasan, Eric W. Cochran

Eric W. Cochran

Presented in this study is a novel recycling strategy for poly(lactic acid) (PLA) in which the depolymerization is rapidly promoted by the base–catalyzed hydrol–/alcohol–ysis of the terminal ester bonds under mild conditions. Post–consumer PLA water bottles were cut into approximately 6 × 2 mm plastic chips and heated to 50–60×C in water, ethanol, or methanol as the depolymerization medium. A variety of carbonate salts and alkaline metal oxides were screened as potential catalysts. High–power ultrasound was also investigated as a means to accelerate the PLA decomposition. Both mass loss and HPLC analysis of ...


Soybean Functional Genomics: Bridging The Genotype-To-Phenotype Gap, Jamie A. O'Rourke, Michelle A. Graham, Steven A. Whitham 2018 United States Department of Agriculture

Soybean Functional Genomics: Bridging The Genotype-To-Phenotype Gap, Jamie A. O'Rourke, Michelle A. Graham, Steven A. Whitham

Steven Whitham

Technological advances coupled with the economic importance of soybean have led to increased efforts to understand gene function and associate genes with phenotypes of agronomic and fundamental interest. Functional genomics approaches aim to develop sufficient understanding needed to bridge the genotype-to-phenotype gap. In general terms, functional genomics approaches begin by using highly parallelized methods to analyze genomes, transcriptomes, proteomes, and metabolomes to generate hypotheses about genes that control phenotypes. Candidate genes are then tested for their contributions to phenotypes through various methods such as RNA silencing, genetic mutation, or overexpression. In this chapter, we review the current approaches, tools, and ...


A Viral Protease Relocalizes In The Presence Of The Vector To Promote Vector Performance, Aurélie Bak, Andrea L. Cheung, Chunling Yang, Steven A. Whitham, Clare L. Casteel 2018 University of California, Davis

A Viral Protease Relocalizes In The Presence Of The Vector To Promote Vector Performance, Aurélie Bak, Andrea L. Cheung, Chunling Yang, Steven A. Whitham, Clare L. Casteel

Steven Whitham

Vector-borne pathogens influence host characteristics relevant to host–vector contact, increasing pathogen transmission and survival. Previously, we demonstrated that infection with Turnip mosaic virus, a member of one of the largest families of plant-infecting viruses, increases vector attraction and reproduction on infected hosts. These changes were due to a single viral protein, NIa-Pro. Here we show that NIa-Pro responds to the presence of the aphid vector during infection by relocalizing to the vacuole. Remarkably, vacuolar localization is required for NIa-Pro’s ability to enhance aphid reproduction on host plants, vacuole localization disappears when aphids are removed, and this phenomenon occurs ...


Knowledge Gained From Good Agricultural Practices Courses For Iowa Growers, Angela M. Shaw, Catherine H. Strohbehn, Linda L. Naeve, Paul A. Domoto, Lester A. Wilson 2018 Iowa State University

Knowledge Gained From Good Agricultural Practices Courses For Iowa Growers, Angela M. Shaw, Catherine H. Strohbehn, Linda L. Naeve, Paul A. Domoto, Lester A. Wilson

Angela M. Shaw

Good Agricultural Practices (GAP) educational courses provide produce growers with the fundamental information for producing and processing safe produce. To determine the effectiveness of the current 7- hour GAP course provided in Iowa, growers were surveyed before and 7-14 days after the course to determine changes in knowledge and opinions. Results show that growers positively changed their knowledge and opinions on key food safety principles and regulations, which provides evidence that Extension programming is an effective method to educate small growers. Food safety educators should focus their training on practical methods for documentation, sanitation, and facilities.


Relationships Between Connection To Community, Perceived Community Outcomes And Individual Well-Being, Becky Vogt 2018 University of Nebraska - Lincoln

Relationships Between Connection To Community, Perceived Community Outcomes And Individual Well-Being, Becky Vogt

Cornhusker Economics

Community attachment or connection to a community has been shown to be related to numerous items. The Knight Foundation’s Soul of the Community project found positive correlations between community attachment and local GDP growth. They also found higher levels of community attachment were related to community social offerings, openness of the community to different types of people and aesthetics of the community. Community attachment has also been related to decreased mobility of residents (people attached to their community are more likely to want to stay there). However, is community attachment also related to perceived change in the community and ...


Wheat Yield And Yield Stability Of Eight Dryland Crop Rotations, David C. Nielsen, Merle F. Vigil 2018 USDA-ARS

Wheat Yield And Yield Stability Of Eight Dryland Crop Rotations, David C. Nielsen, Merle F. Vigil

David C. Nielsen

The winter wheat (Triticum aestivum L.)–fallow (WF) dryland production system employed in the Central Great Plains has evolved in the past 40 yr to include a diversity of other crops, with a reduction in fallow frequency. Wheat remains the base crop for essentially all cropping systems. Decisions to change a farming system benefit from information about average wheat yields, yield stability, and probabilities of obtaining a specified minimum wheat yield. The objective of this experiment was to quantify wheat yields, yield stability, and the probability of obtaining a specified minimum yield in eight dryland rotational systems varying in cropping ...

Influence Of Dietary Ractopamine And Supranutritional Supplementation Of Vitamin E On Proteome Profile Of Postmortem Beef Longissimus Lumborum Muscle, Hyun Mok Kim 2018 University of Kentucky

Influence Of Dietary Ractopamine And Supranutritional Supplementation Of Vitamin E On Proteome Profile Of Postmortem Beef Longissimus Lumborum Muscle, Hyun Mok Kim

Theses and Dissertations--Animal and Food Sciences

The effects of dietary ingredients on the proteome profile of postmortem beef longissimus lumborum (LL) muscle were evaluated. In the first experiment, the influence of dietary ractopamine on the whole-muscle proteome of beef LL was examined. Five proteins were differentially abundant between ractopamine-fed (RAC) and non-ractopamine fed (CON) groups. The differentially abundant proteins were over-abundant in RAC and were related to muscle structure development (F-actin-capping protein subunit beta-2 and PDZ and LIM domain protein-3), chaperone (heat shock protein beta-1), oxygen transportation (myoglobin), and glycolysis (L-lactate dehydrogenase A chain). These findings indicated that ractopamine influences the abundance of proteins associated with ...


Economic Growth And Changes In Forested Areas In Southeast Asia: Is Environmental Kuznets Curve Still Relevant?, Lan Thi Ngoc Nguyen 2018 Hollins University

Economic Growth And Changes In Forested Areas In Southeast Asia: Is Environmental Kuznets Curve Still Relevant?, Lan Thi Ngoc Nguyen

Undergraduate Honors Theses

The environmental history of the twentieth century in Southeast Asia reveals tremendous loss of forested areas as a consequence of unprecedented economic transformations and unrestrained globalization. Featuring some of the world’s fastest-growing economies, Southeast Asia has been experiencing fundamental changes in its economic structure, sociopolitical institutions, and the rate of natural resources extraction and depletion, including deforestation. This study reexamines evidence of the (EKC) hypothesis in light of the deforestation the above region experienced over the period 1990-2013. We use the change in forest cover as an indicator for environmental degradation. A panel co-integration approach is invoked to investigate ...


Tomato Cultivar Evaluation In High Tunnels, Northern Indiana, 2017, Elizabeth Maynard, Erin A. Bluhm 2018 Purdue University - Main Campus

Tomato Cultivar Evaluation In High Tunnels, Northern Indiana, 2017, Elizabeth Maynard, Erin A. Bluhm

Purdue Fruit and Vegetable Research Reports

Tomatoes are a common crop grown in unheated greenhouses, commonly called high tunnels. Production in these structures has increased in recent years. This trial was conducted to evaluate varieties for their performance as a summer-harvested crop in soil-based high tunnel production systems. Five hybrid determinate varieties or line, one hybrid indeterminate, and one open-pollinated indeterminate variety were compared for yield, earliness, fruit size, and quality.
