When it was first adopted as a crop, switchgrass was evaluated and improved for forage uses; but it has more recently been extensively studied as an energy crop, where its biomass might be used as feedstock for bioenergy. Of the two morphological forms or cytotypes of switchgrass, the lowland cultivars tend to produce more biomass; but upland cultivars are(More)
Switchgrass is being widely considered as a feedstock for biofuel production. Much remains to be learned about ideal feedstock characteristics, but switchgrass offers many advantages already and can perhaps be manipulated to offer more. When planning to grow switchgrass, select a cultivar that is well adapted to the location - generally a lowland cultivar(More)

In the next quarter-century, global demand for energy is expected to increase more than 25%, while some analysts are predicting that output of petroleum will soon peak. This reality of increasing demand in the face of diminishing fossil supplies is spurring interest in renewable energy sources. An array of biomass-for-bioenergy resources has been proposed,(More)
Switchgrass (Panicum virgatum L.), a perennial warm-season grass indigenous to the eastern USA, has potential as a biofuels feedstock. The objective of this study was to investigate the performance of upland and lowland switchgrass cultivars under different environments and management treatments. Four cultivars of switchgrass were evaluated from 2000 to(More)
(ABSTRACT) A series of studies were conducted to examine the antioxidant status, drought and disease tolerance, and growth response to foliar application of soluble seaweed (Ascophyllum nodosum) extracts (SE) and humic acid (HA; 25% active HA or 2.9% active HA) in tall fescue (Festuca arundinacea Schreb), Kentucky bluegrass (Poa pratensis L.) and creeping(More)
