Effect of cultivar on yield, chemical composition and British Thermal Unit content of three Switchgrass {Panicum Virgatum L.) cultivars

摘要

Switchgrass varieties with different sowing times and years of cultivation may change nutrient parameters, dry matter production and bio-fuel characteristics expressed as British Thermal Unit (BTU). The objective of this study was to report the effectof cultivar on dry matter yield, chemical composition and bio-fuel value of three Switchgrass (Pani-cum Virgatum L.) cultivars. Fossil fuel usage is a key human-related factor contributing to the production of green house gases. Biomass conversion intoforms of energy is an old idea but one that is receiving increasing attention largely because of environmental, energy supply and agricultural market condition concerns (McCarl and Schneider 2001).
