Sweet Sorghum Yield and Quality in Current and Future Climates of Oklahoma.

Feedstock production is key to the successful implementation of a biobased economy that addresses the Oklahoma State Energy Program (SEP) mission to “reduce reliance on imported energy.”  Using high yielding feedstocks with available technologies for ethanol production is the quickest way forward to achieve the states’ specific goal of reducing per capita energy consumption by at least 25% (of the states’ 1990 per capita energy use) by 2012. . Currently, energy input to output for sorghum is 1:8. Variety x plant population x nitrogen experiments were conducted during 2008 and 2009 at SERC at Chickasha, OK. Biomass yield, juice yield and juice quality were determined. The APSIM sweet sorghum model was used to predict sweet sorghum yield and quality in current and future climates.
