Quantifying Selfing and Outcrossing Fertility in Lowland Swtichgrass Populations Using Ssr Markers
(Oklahoma State University, 2012-12-01)
Switchgrass (Panicum virgatum L.), a native C4 perennial species, is being developed as a major cellulosic crop for biofuel feedstock production in the U.S. However, no information is available on mating behavior of plants ...
Parameterization and Application of the Aquacrop Model for Simulating Bioenergy Crops in Oklahoma
(Oklahoma State University, 2012-07-01)
The objective of this study was to parameterize the AquaCrop model for two bioenergy crops, switchgrass and forage sorghum, using field measurements from Stillwater, Oklahoma in 2011. The parameterized model was then ...
Economic and Environmental Tradeoffs from Switchgrass and Ethanol Production (A Case in Oklahoma)
(Oklahoma State University, 2012-07-01)
In this study IMPLAN 2009 economic data, CEDA 4.41 environmental data and other data sources are used to determine the economic and environmental impact associated with switchgrass based ethanol production in Oklahoma. The ...
Developing a Budget to Plant, Harvest, and Transport Switchgrass
(Oklahoma State University, 2009-12-01)
If there is any hope of moving away from fossil fuels, and towards renewable alternatives, a comprehensive economics analysis of the problem must be performed. This study is the first step in a larger economic analysis ...
Identification of micrornas and their targets in switchgrass, a model cellulosic biofuel plant species
(2010-12)
Scope and Method of Study:
Influence of switchgrass management on soil microbial biomass and fatty acid methyl ester content in soil
(2020-07)
Switchgrass is a fairly new source of commercial biofuel feedstock. Its production can potentially preserve soil health and microbial functions in ecosystems. There is an increasing demand for large scale biomass production, ...
Tradeoff between water yield and biomass production associated with eastern redcedar encroachment into grassland ecosystems
(2019-12)
Eastern redcedar (Juniperus virginiana) is encroaching tallgrass prairie ecosystems in the southern Great Plains disrupting multiple ecosystem services provided by these ecosystems. While not suitable for row crop production, ...
Net ecosystem exchange of carbon dioxide and water vapor fluxes in switchgrass and high biomass sorghum
(2013-12)
Understanding carbon and water dynamics of switchgrass (Panicum virgatum L.) and high biomass sorghum ((Sorghum bicolor L. Moench) ecosystems is crucial as the acreage of these feedstocks is expanding for cellulosic biofuels. ...
Plant Stress and Drivers in Ecosystem Sustainability
(Oklahoma State University, 2011-12-01)
We sampled switchgrass ( Panicum virgatum L.) in adjacent fields near Medford, OK. Fields were either enrolled in CRP or were considered old field. Switchgrass in the CRP plots appeared to have a higher soluble protein ...
Production economics of potential perennial and annual biomass feedstocks
(2012-05)
Scope and Method of Study: The first essay determines the lowest cost lignocellulosic biomass feedstock production system for western Oklahoma from among seven alternatives at each of two locations. Field experiments were ...
