In the recent years sweet sorghum is emerging as an important feedstock for bioethanol production. It was observed that total soluble sugar yield (TSSY) increases with time in the post-anthesis phase depending on the length of crop cycle. The qualitative and quantitative sugar loss of up to 50% or more occurs due to delay in harvest during post-physiological maturity stage depending on the genotype, weather and soil conditions, and the time lag between harvest and crushing of the stalks. Hence… Expand
