Effect of time lag after harvesting for cane crushing on juice and Brix in genotypes of high energy sorghum.

High-energy sorghums are types of Sorghum bicolor that produce high grain yields and whose sweet stalks yield enough biomass and carbohydrates for processing into alcohol or sugar. An advantage is their short maturity period (100-120 days), which can be planned to provide sugar when cane sugar factories are idle; a particular disadvantage is the rapid loss of sucrose between harvesting and juice extraction. Five high-energy sorghum genotypes (HES 2, HES 3, HES 4, HES 6 AND HES 13) were grown in medium black soil during kharif 1988-89; panicles were gathered one week after physiological maturity and the stems were harvested, to be crushed after delays of up to 4 days. Juice yield, Brix and weight loss of stems are compared. Brix at harvest was highest (17.0) in HES 13, and lowest (9.7) in HES 3; weight loss [average of all storage periods? ] was lowest (5.12%) for HES 13 and highest (8.98%) for HES 3. Over the 4-day period, weight loss averaged 15.73%, average juice yield decreased from 41.7 to 37.6%, and average Brix increased from 14.4 to 18.0.
