Data from: Temporal and spatial variation in switchgrass biomass composition and theoretical ethanol yield

Information on temporal and spatial variation in switchgrass (Panicum virgatum L.) biomass composition as it affects ethanol yield (L Mg–1) at a biorefinery and ethanol production (L ha–1) at the field-scale. Switchgrass biomass samples were collected from a regional, on-farm trial and biomass composition was determined using developed near-infrared reflectance spectroscopy (NIRS) prediction equations and theoretical ethanol yield (100% conversion efficiency). Data comprises of forage quality components and cell wall composition parameters specific to the bioenergy sector. Switchgrass was harvested during the reproductive growth stage.
