Although global food demand is expected to increase 60% by 2050 compared with 2005/2007, the rise will be much greater in sub- Saharan Africa (SSA). Indeed, SSA is the region at greatest food security risk because by 2050 its population will increase 2.5-fold and demand for cereals approximately triple, whereas current levels of cereal consumption already depend on substantial imports. At issue is whether SSA can meet this vast increase in cereal demand without greater reliance on cereal imports or major expansion of agricultural area and associated biodiversity loss and greenhouse gas emissions. Recent studies indicate that the global increase …

Mapping The Impact Of Intensive Rotational Grazing On Soil Fertility Over Time On Greenbrier Farms In Pickens County, South Carolina, Emily Kirby

Earth and Environmental Sciences Presentations

Intensive rotational grazing (IRG) is a management technique that involves a more intentional management approach which includes increased paddock numbers, shorter grazing periods, larger livestock presence per acre, and longer periods of rest on pastures. Potential advantages of this management technique include improved forage quality, greater yield, decreased erosion, stable production during adverse growing condition, and improved soil fertility. This study collects and analyzes data to understand the impact of rotational grazing on soil fertility as measured by SOC (soil organic carbon) and SON (soil organic nitrogen) on Greenbrier Farms in Easley, South Carolina. This study analyzes the transition from …

More than 100 countries pledged to reduce agricultural greenhouse gas (GHG) emissions in the 2015 Paris Agreement of the United Nations Framework Convention on Climate Change. Yet technical information about how much mitigation is needed in the sector vs. how much is feasible remains poor. We identify a preliminary global target for reducing emissions from agriculture of ~1 GtCO2e yr−1 by 2030 to limit warming in 2100 to 2 °C above pre-industrial levels. Yet plausible agricultural development pathways with mitigation cobenefits deliver only 21–40% of needed mitigation. The target indicates that more transformative technical and policy options will be needed, …

Mechanism Of Resistance, Gene Flow, And Integrated Management Of Ragweeds (Ambrosia) In Nebraska, Zahoor Ahmad Ganie

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Common ragweed (Ambrosia artemisiifolia L.) and giant ragweed (Ambrosia trifida L.) are native annual broadleaf weeds in the United States found in diverse agroecosystems, roadsides, and wastelands. They are economically important weed species in the Midwest and sources of pollen allergies. Confirmation of glyphosate-resistant (GR) common and giant ragweed in Nebraska justified the need to determine the mechanism of resistance, dispersal of resistance genes via pollen, and to develop an integrated management program. The objectives of this research were to: 1) determine the mechanism of glyphosate resistance in a common ragweed biotype from Nebraska; 2) evaluate the effect …

Characterization Of Ground Nozzles For Pesticide Applications, Ryan Henry

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Pesticide applications are a common component of crop production systems in the United States (US). For row crop systems (e.g. corn, soybean, or wheat), pesticides are applied by ground, aerial, or chemigation methods. The exact method of pesticide delivery is not universally regulated/ prescribed in the US, and the equipment and application technique are largely defined by the individual applicator. A wide variety of choices and decisions must be made by applicators to result in a successful pesticide application. Examples of these choices include proper active ingredient(s), carrier volume and equipment (e.g. nozzle type, spacing, and operating pressure) selection while …

Evaluations Of Biological Control Agents For The Management Of Soybean Cyst Nematode (Heterodera Glycines) In Soybean (Glycine Max L. Merr.), Kelsie M. Musil

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

The soybean cyst nematode (SCN, Heterodera glycines) is the most yield limiting pathogen of soybeans (Glycine max L. Merr.). Current management strategies of crop rotation and using resistant varieties are not completely effective and alternative management strategies are needed. Commercial seed treatments with biological agents are available to protect against yield loss from SCN, but have not been evaluated in Nebraska. Field studies were conducted in eight Nebraska locations (six infested with SCN and two non-infested) during 2014 and 2015 to evaluate seed treatment effects on soybean establishment, SCN population density, and yield. The seed treatments were CruiserMaxx® …

The Regeneration Of Aspen Stands In Southern Utah, Justin Britton, Justin Derose, Karen Mock, Darren Mcavoy

All Current Publications

This fact sheet describes research conducted at Utah State University that identified factors to improve the success of regenerating aspen in southern Utah. Evaluating past silvicultural regeneration treatments indicated that the presence of pre-harvest advance reproduction, site preparation by broadcast burning, and decreasing browsing pressure could increase the quantity of aspen regeneration. The outcomes are generalized into an easy-to-use model, the Aspen Pyramid, to facilitate decision-making regarding regenerating aspen.

The Role Of Interdisciplinary Scholarship And Research To Meet The Challenges Facing Agriculture In The 21st Century, Joshua Jay Miller

Doctor of Plant Health Program: Dissertations and Student Research

Throughout human history, scientific advancements have increased our understanding of the physical world. However, as our breadth of knowledge has increased, scholarship and research have become increasingly more specialized in order to add to the body of knowledge. University structures encourage this specialization through disciplinary learning and discovery. Although this model is necessary to continue growing the body of knowledge, the complex issues facing humanity, especially in regards to agriculture, require solutions that no single discipline can provide. These issues require an interdisciplinary approach to integrate the insights across multiple disciplines. Interdisciplinarity can be achieved through collaborative processes, but these …

Global climate change (GCC) is projected to bring higher-intensity precipitation and higher-variability temperature regimes to the Northeastern United States. The interactive effects of GCC with anthropogenic land use and land cover changes (LULCCs) are unknown for watershed level hydrological dynamics and nutrient fluxes to freshwater lakes. Increased nutrient fluxes can promote harmful algal blooms, also exacerbated by warmer water temperatures due to GCC. To address the complex interactions of climate, land and humans, we developed a cascading integrated assessment model to test the impacts of GCC and LULCC on the hydrological regime, water temperature, water quality, bloom duration and severity …
