Determining Best Management Practices for High Biomass Sorghum.

Interaction studies with varieties (1990 and Sordan headless), row spacing (7.5, 15, and 30 in) and nitrogen (0, 75, 150 and 225 lb/acre) were conducted during 2008 and 2009 at SERC, Chickasha, OK. The design wassplit-split-plot design with four replications. An array of data sets was collected that provided details on crop growth and development, biomass yield, and quality during both years of the study.  Monthly dry weights of plants during the growing season were collected.  Plants were separated into stems, leaves and grain (if applicable) and sent for nutrient and quality analysis to the Soil, Water and Forage Analytical Laboratory at Oklahoma State University.
