The experiment was conducted with ten cultivars of sweet sorghum to know the ethanol recovery and biochemical composition from stalk juice and grain. At physiological maturity, maximum recovery of ethanol(9.12%) was obtained from the stalk juice of NSS-208, which was found to be highest in total sugar (17.40%) and lowest in reducing sugar (1.46%). The AKSSV-24 cultivar was also showed higher ethanol.recovery (9.03%). The significantly superior grain starch content were reported by NSS-104 (72.5%) and Keller (71.6 %) which ultimately turned to maximum yield of grain ethanol Le. 44.96 and 44.57 %respectively. Further biochemical analysis of grain revealed that maximum amylose and amylopectin were found· in NSS-I04 followed by Keller, as well as NSS-104 found significantly superior in fat content (4.3%). Maximum content of phenol was observed in BJ-248 (0.7%). Amongst all, grain malt of BJ-248 recorded highest diastatic power (45.82. DUg-1) followed by NSS-04 (41.65 DUg-1). The analysis of bagasse remained after extraction of juice reported that cellulose and lignin content was maximum in bagasse of NSS-104 where as highest percentage of hemicellulose was obtained in bagasse of Wray.
