Biological and Agronomic Aspects of Two Insect Predators of Switchgrass
… a potential model for an alternative fuel source in North America. Recently, two insect pests of switchgrass have been identified. The switchgrass moth [Blastobasis repartella (Dietz): Lepidoptera: Coleophoridae] feeds in the basal internodes and in rhizomes, causing premature tiller and rhizome …

The potential implications of bioenergy crop production for water and energy balance and carbon and nitrogen dynamics in the United States
In this dissertation, I systematically investigate the impacts of large-scale growth of bioenergy crops on water and energy balance and coupled carbon and nitrogen dynamics in the US. To achieve this objective, I apply and extend a coupled biogeochemical and biogeophysical model, the Integrated …

Switchgrass Cultivar, Harvest Frequency, Fertilizer Source, and Irrigation Effects on Near-Surface Soil Properties in West-Central Arkansas
… fuel generation. Agronomic management combinations that maximize monoculture switchgrass yield are generally well understood; however, little is known about corresponding effects of differing switchgrass management combinations on near-surface soil properties. The objective of this research …

Compatibility, Yield, and Quality of Warm-Season Grass-Legume Mixtures
… is a major limitation to livestock production in the mid-Atlantic region. Perennial warm-season grasses might provide a solution if managed for high quality. Experiments were conducted on separate well-established stands of Caucasian bluestem and 'Cave-in-Rock' switchgrass at the Kentland Farm …

Switchgrass potential on reclaimed surface mines for biofuel production in West Virginia
… with non-renewable energy sources has caused an increased interest in, and development of renewable biofuels. Switchgrass (Panicum virgatum L.), a warm season perennial grass, has been investigated as a source of biofuel feedstock due to its high biomass production on marginal soils, its …

Switchgrass as an Energy Crop: Fertilization, Cultivar, and Cutting Management
… a biofuels feedstock. Major management questions include cultivar selection, cutting management, and optimizing N fertilization. Four cultivars of switchgrass were evaluated under two cutting regimes at eight locations within KY, NC, TN, VA, and WV in 2000 and 2001. Harvests were made once (in …

Evaluation of Prairie Cordgrass (Spartina pectinat, link) for Biomass Production on Marginal Land
… and farmers to search for new crops that increase agricultural sustainability and profitability. The use of bioenergy crops such as switchgrass and prairie cordgrass will help to meet future energy and biomass needs through the process of converting crop biomass into bioenergy sources with …

Switchgrass tolerance to cadmium: uptake and translocation
Recent efforts have been initiated to develop switchgrass (Panicum virgatum L.) as a bioenergy crop. Switchgrass requires input of nitrogen (N) to be productive. Alternatives to inorganic fertilizers are needed to reduce input costs and maintain a positive energy balance. Municipal sludge may be an …

Water relations and cutting management of switchgrass
… L.), a warm-season grass, grows most rapidly in mid-summer when cool-season species such as tall fescue (Festuca arundinacea Schreb.) may have limited growth due to high temperature and low soil moisture availability. The objectives of this study were to investigate physiological factors and …

Utilizing Beneficial Bacterial Endophytes to Promote Switchgrass Growth in Low- input Agricultural Production Systems
… of Energy has focused research efforts on developing switchgrass into a bioenergy feedstock, helping to offset the use of non-renewable fossil fuels and make the US more energy independent. Bacterial endophytes, which reside inside plant tissues, are proven to increase yield and stress resistance …

Seasonal Dynamics of Productivity and Photosynthesis of Three Biofuel Feedstocks: Field Comparisons of Miscanthus X Giganteus, Panicum Virgatum and Zea Mays
Global climate change and dwindling supplies of fossil based resources have led to increasing interest in the use of plant biomass as an alternative fuel source. One of the major limitations is in the amount of land area available to meet the needs of the expanding global population. To provide …
