Cover Crop Effect On Subsequent Wheat Yield In The Central Great Plains, David Nielsen, Drew Lyon, Robert Higgins, Gary Hergert, Johnathon Holman, Merle Vigil 2016 Washington State University

Cover Crop Effect On Subsequent Wheat Yield In The Central Great Plains, David Nielsen, Drew Lyon, Robert Higgins, Gary Hergert, Johnathon Holman, Merle Vigil

David C. Nielsen

Crop production systems in the water-limited environment of the semiarid central Great Plains may not have potential to profitably use cover crops because of lowered subsequent wheat (Triticum asestivum L.) yields following the cover crop. Mixtures have reportedly shown less yield-reducing effects on subsequent crops than single-species plantings. This study was conducted to determine winter wheat yields following both mixtures and single-species plantings of spring-planted cover crops. The study was conducted at Akron, CO, and Sidney, NE, during the 2012–2013 and 2013–2014 wheat growing seasons under both rainfed and irrigated conditions. Precipitation storage efficiency before wheat planting, wheat ...

Detection And Quantification Of Airborne Conidia Of Fusarium Circinatum, The Causal Agent Of Pine Pitch Canker, From Two California Sites Using A Real Time-Pcr Approach Combined With A Simple Spore Trapping Method, Wolfgang Schweigkofler, Kerry O'Donnell, Matteo Garbelotto

Wolfgang Schweigkofler

Pinus radiata (Monterey pine), a tree native to coastal California and Mexico, is widely planted worldwide for timber production. A major threat to Monterey pine plantations is the fungal disease pine pitch canker, caused by Fusarium circinatum (Hypocreales). We present a novel trapping approach using filter paper in combination with a rapid molecular method to detect the presence of inoculum in the air. The assay is also useful for diagnosing the presence of the pathogen on plants. The test is based on the F. circinatum specific primer pair CIRC1A-CIRC4A, which amplifies a 360-bp DNA fragment in the intergenic spacer region ...


Exploration Of Chemical And Biological Management Strategies For Diaphorina Citri The Primary Vector Of Candidatus Liberibacter Asiaticus, Gretta Marie Sharp 2016 University of Texas at Tyler

Exploration Of Chemical And Biological Management Strategies For Diaphorina Citri The Primary Vector Of Candidatus Liberibacter Asiaticus, Gretta Marie Sharp

Biology Theses

Diaphorina citri (Hemipteran: Psyllidae), the Asian citrus psyllid, is a phloem-feeding, invasive species endemic to southern Asia that was first identified in the United States in Florida in 1998. Since introduction, D. citri has spread across the major citrus growing regions of the United States. This is of great concern to the citrus industry because D. citri is the primary vector of Candidatus Liberibacter asiaticus the causal agent of Haunglongbing (HLB). Haunglongbing is the most economically devastating disease of citrus causing an estimated 8.92 billion dollars lost in revenue and 4.62 billion dollars lost in gross domestic product ...


Complex Effects Of Value-Added Livestock Ventures, Matthew A. Diersen 2016 South Dakota State University

Complex Effects Of Value-Added Livestock Ventures, Matthew A. Diersen

Economics Commentator

Value-added agriculture ventures are generally touted as being positive for a region’s economy. A product formerly shipped elsewhere may now be processed or modified locally or regionally, providing additional employment and related economic activity. Ethanol production, for example, disrupts the pattern of sending corn out of a region, but usually occurs where corn production is already prevalent. Consider, instead, the implications of a new livestock production facility. In this article, observations are made at the state and county levels related to livestock ventures. Kingsbury County is examined for potential effects on the production agriculture (or farming) sector. A livestock ...


Characterization Of Extraction Methods To Recover Phenolic-Rich Extracts From Black Beans (Phaseolus Vulgaris) That Inhibit Alpha-Amylase And Alpha-Glucosidase Using Response Surface Approaches, Mazen Alharbi 2016 University of Nebraska-Lincoln

Characterization Of Extraction Methods To Recover Phenolic-Rich Extracts From Black Beans (Phaseolus Vulgaris) That Inhibit Alpha-Amylase And Alpha-Glucosidase Using Response Surface Approaches, Mazen Alharbi

Nutrition & Health Sciences Dissertations & Theses

Black beans contain high phenolic contents that are considered potent antioxidants. Relatively little is known about their ability to inhibit the carbohydrate-hydrolyzing enzymes α-amylase and α-glucosidase from releasing glucose from starch and/or disaccharides. The objective of this project was to determine the optimum procedures for extracting total phenols (TP), total flavonoids (TF) and total condensed tannins (TCT) from black beans (Phaseolus vulgaris), and then to determine the ability of the phenolic rich extracts to inhibit α-amylase and α-glucosidase. Due to their high phenolic levels, it was hypothesized that black beans would be an effective inhibitor of α-amylase and α-glucosidase ...


Behavioral Determinants Of Biofortified Food Acceptance: The Case Of Orange-Fleshed Sweet Potato In Ghana, Chinonso E. Etumnu 2016 University of San Francisco

Behavioral Determinants Of Biofortified Food Acceptance: The Case Of Orange-Fleshed Sweet Potato In Ghana, Chinonso E. Etumnu

Master's Theses

Biofortified foods are being introduced in sub-Saharan Africa as an important strategy to help address micronutrient malnutrition. However, there has been little research on factors that could play decisive roles in their successful introduction. This paper investigates the determinants of consumer acceptance of biofortified orange-fleshed sweet potato (OFSP) using data from a choice experiment conducted in Ghana. I find that OFSP is preferred to traditional white-fleshed and yellow-fleshed sweet potatoes as indicated by consumers' marginal willingness to pay for the three varieties. I also find that respondents' socio-economic characteristics do not have a significant effect on consumer acceptance of OFSP ...

This project is an exploration of how agriculture can be incorporated into the fabric of the city of Chula Vista, which has both uniquely urban and suburban areas. The proposal is to integrate agriculture as a design tool to reconnect to the city’s agricultural past and as a model for cities of the future. First, I discuss Chula Vista’s history and contemporary context, including demographics. I review the existing urban agriculture policies Chula Vista has and compare them to other cities in California. The second part of the project is concerned with how to choose and develop a ...


Evaluating Soil Tillage Practices Using X-Ray Computed Tomography And Conventional Laboratory Methods, Maria Ambert-Sanchez, Steven K. Mickelson, Syed I. Ahmed, Joseph N. Gray, David F. Webber 2016 Peace Corps

Evaluating Soil Tillage Practices Using X-Ray Computed Tomography And Conventional Laboratory Methods, Maria Ambert-Sanchez, Steven K. Mickelson, Syed I. Ahmed, Joseph N. Gray, David F. Webber

Steven K. Mickelson

Using x-ray computed tomography (CT) for non-destructive 3-D imaging and analysis of soil physical properties has been investigated for over 30 years. However, applying this system in soil science has remained a specialized research area using primarily low-resolution medical-grade x-ray CT units that were not designed for soil analysis applications. The main research objectives were to characterize and compare physical properties of soil core samples from long-term chisel plow (CP) and no-till (NT) agricultural field management sites using a high-resolution industrial-grade x-ray CT unit and two conventional soil laboratory method (SLM) soil macroporosity analysis procedures. Field research activities during 1999 ...

Buffer Strips For Controlling Herbicide Losses, Steven K. Mickelson, James L. Baker

Steven K. Mickelson

Buffer strips are considered effective for reducing runoff of sediment and agricultural chemicals from cropland. In fact, buffer strips, or vegetative filter strips, have been suggested as a Best Management Practice to reduce nonpoint source pollution from cropland. This pollution can be great, especially if rainfall occurs shortly after a chemical has been applied.

Livestock Manure Windrow Composting Runoff And Infiltration Characteristics From Laboratory Rainfall Simulations, David F. Webber, Steven K. Mickelson, Bryan D. Whitman, T. L. Richard, Heekwon Ahn 2016 Iowa State University

Livestock Manure Windrow Composting Runoff And Infiltration Characteristics From Laboratory Rainfall Simulations, David F. Webber, Steven K. Mickelson, Bryan D. Whitman, T. L. Richard, Heekwon Ahn

Steven K. Mickelson

Windrow-composted livestock manure has been shown to be less hazardous to the environment compared to manure directly applied to cropland and other agricultural areas. Although offsite contaminant losses through runoff and leaching can occur during the composting process, these losses are suspected to increase under different compost moisture conditions and as composted materials mature. This research quantified the effects of windrow-composted livestock manure and straw bedding components on runoff and infiltration characteristics from laboratory rainfall simulations. Compost samples collected on three dates at approximately the beginning (day 0), middle (day 30), and end (day 60) of a June-July 2004 field ...
