Membrane Lipid Extraction Methods From Sorghum Bicolor, Max Regester

Honors Program: Senior Projects (Public)

Plants are the basis of the world as we know it. As sessile beings, there are often subject to many environment stressors like drought, extreme temperatures, etc. One way of analyzing how plants respond to these stressors is by monitoring changes in their lipid compositions. Having a better understanding of how plants respond to different stressors can have very important implications when it comes to cultivating crops. When testing lipid composition, it is important to measure levels as they were in the living tissue. The problem is, enzymes known as lipases are active during extraction and can greatly change the …

Influence Of Furrow Tillage And Nitrogen Fertilizer Management On Water Quality And Soil Nitrogen Dynamics In Arkansas Irrigated Cotton, Hunter Wood-Pointfield

Student Theses and Dissertations

Furrow irrigation can increase potential for soil erosion and nutrient losses in agricultural cropping systems. A field experiment to examine furrow tillage and N fertilizer application was conducted in irrigated cotton in northeastern Arkansas. Treatments included a conventional sweep plow or conservation plow to clear water furrows and either a subsurface band of 32% urea ammonium nitrate (UAN) or broadcast urea. Runoff water was collected throughout the experiment at the edge of field, and analyzed for water quality. Soil samples of four depths (0-90 cm) were taken during key crop development stages and analyzed for soil exchangeable N. Soluble nutrients …

Increased Usage Of Cash Rent: Factors Influencing Illinois Farmland Leases Over The Past Two Decades, Jacob Styan

Theses and Dissertations

In recent years, cash rent leases have become increasingly popular amongst farm landowners in Illinois.

The rise in cash rent lease usage has been attributed to many factors such as crop yields, commodity prices, crop revenue, commodity payments, and crop insurance. This study aims to determine which factors are the most pivotal in …

German Immigration And Its Ties To Landscape Change In Nebraska, Lindsey Labrie

Honors Program: Senior Projects (Public)

This thesis uses a multidimensional approach to frame the different waves of German immigration within the context of land use change in Nebraska. By recounting the historical challenges and struggles Germans faced in their homelands, this thesis provides similarities between historical immigration patterns throughout the state. Observing the timing of these movements of people paints a clearer picture of how these immigrants might have helped change the farming and cultural landscapes of Nebraska. Knowing and recognizing historical immigration in Nebraska cultivates a deeper appreciation for the current relations between immigrants and Nebraska’s physical landscape.

Optimum Rates Of Surface-Applied Coal Char Decreased Soil Ammonia Volatilization Loss, Dinesh Panday, Maysoon M. Mikha, Harold P. Collins, Virginia L. Jin, Michael Kaiser, Jennifer Cooper, Arindam Malakar, Bijesh Maharjan

Department of Agronomy and Horticulture: Faculty Publications

Fertilizer N losses from agricultural systems have economic and environmental implications. Soil amendment with high C materials, such as coal char, may mitigate N losses. Char, a coal combustion residue, obtained from a sugar factory in Scottsbluff, NE, contained 29% C by weight. A 30-d laboratory study was conducted to evaluate the effects of char addition on N losses via nitrous oxide (N₂O) emission, ammonia (NH₃) volatilization, and nitrate (NO₃–N) leaching from fertilized loam and sandy loam soils. Char was applied at five different rates (0, 6.7, 10.1, 13.4, and 26.8 Mg C ha …

Familiarity And Use Of Veterinary Services By Us Resident Dog And Cat Owners, Courtney Bir, Mario Ortez, Nicole Olynk Widmar, Chris Wolf, Charlotte Hansen, Frederic B. Ouedraogo

Department of Agricultural Economics Faculty Publications

Pet ownership, veterinary use, and beliefs regarding veterinary care were elicited through the use of a nationally representative survey of 997 U.S. residents. Fifty-one percent of respondents have or had a dog in the past five years and 37% have or had a cat in the past five years. Over ninety percent of cat and dog owners had visited a veterinarian at any time, but only about 40% visited a veterinarian annually. With the rise of options in veterinary medicine, including low-cost options for vaccines and spay/neuter, further study and analysis of pet-owners use of veterinary care is warranted. Fifty-four …

Perceptions Of Prominent Animal Welfare And Veterinary Care Organizations In The United States, Mario Ortez, Courtney Bir, Nicole Olynk Widmar, Chris Wolf

Department of Agricultural Economics Faculty Publications

U.S. residents’ perceptions of the impact of prominent animal welfare and veterinary care organizations on pet animal well-being and health care may not be linked to the organization’s stated mission and effectiveness in advancing it, but to the level of recognition people have for the groups. An online survey of 1000 U.S. residents was used to understand the perceived impact of organizations with self-stated dedication to pet animal well-being. Using a Likert-scale, respondents ranked 13 prominent organizations as having a low to high impact on pet animal well-being and health care. The American Society for the Prevention of Cruelty to …

Short-Run Net Returns To A Cereal Rye Cover Crop Mix In A Midwest Corn–Soybean Rotation, Nathan Thompson, Shalamar Armstrong, Richard T. Roth, Michael D. Ruffatti, Carson Reeling

Department of Agricultural Economics Faculty Publications

Unsubstantiated economic returns are a major contributor to producers’ reluctance to adopt cover crops. The objective of this study is to evaluate the direct short-run net returns to the producer of implementing a predominantly cereal rye (Secale cereal L.) cover crop mix into a Midwest corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotation. Experimental agronomic data from field experiments in Lexington, IL, are used to calibrate economic simulations of the costs and benefits of cover crop adoption. Results indicate that net returns to cover crops, including current cost-share payments, were routinely negative. Returns to the soybean …

Geographic Variation In The Genetic Basis Of Resistance To Leaf Rust Between Locally Adapted Ecotypes Of The Biofuel Crop Switchgrass (Panicum Virgatum), Acer Van Wallendael, Jason Bonnette, Thomas E. Juenger, Felix B. Fritschi, Philip A. Fay, Robert B. Mitchell, John Lloyd-Reilley, Francis M. Rouquette Jr, Gary C. Bergstrom, David B. Lowry

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Local adaptation is an important process in plant evolution, which can be impacted by differential pathogen pressures along environmental gradients. However, the degree to which pathogen resistance loci vary in effect across space and time is incompletely described.

To understand how the genetic architecture of resistance varies across time and geographic space, we quantified rust (Puccinia spp.) severity in switchgrass (Panicum virgatum) plantings at eight locations across the central USA for 3 yr and conducted quantitative trait locus (QTL) mapping for rust progression.

We mapped several variable QTLs, but two large-effect QTLs which we have named Prr1 and Prr2 were …
