A field experiment was conducted at the Agricultural College Farm, Dharwad during Kharif 19889-89 with a view to understand the effect on quality characters in four sweet sorghum genotypes. Genotypes Rio was found to be superior followed by SSV-119 in grain yield, sugar yield, extractable juice per cent and Brix value. Sugar content in stem was maximum at physiological maturity (120 DAS) in all the genotypes and the quality of stalk juice was superior at this stage. Grain yield and extractable juice percent of Rio increased with an increase in nutrient level from 40:20:10 kg to 100:60:30 kg NPK/ha
