Abstract


With an objective of identifying the sweet sorghum variety that produces high biomass higher green fodder yield as well as suited for ethanol production, fourteen sweet sorghum genotypes along with three checks were evaluated for two years at Main Agricultural Research Station, University of Agricultural Sciences Dharwad. Among the 17 genotypes studied SSV-74 recorded higher LAI (9.13) and TDM (2407.7g/m2) at flowering, higher fresh cane weight (9.710 kg/m2) and brix value (16.2) at maturity. The promising ones were evaluated for their performance over locations. Further, it was found better than checks DFJ 1 and SSV 84 for high fodder yield at different locations and over years. Regarding reaction to important pests and diseases of sorghum, SSV 74 exhibited better tolerance than both the checks. Silage quality of this outstanding variety was on par with popular fodder maize variety South African tall, but better than DEJ 1.  Looking to the  better performance SSV 74 for higher cane yield  at all the stages of growth higher juice yield and brix value at maturity along with good grain yield at physiological   maturity, it can be considered as good fodder variety.
