Evaluation of sorghum genotypes under varied fertilizer levels for fodder yields and quality

Abstract

Sorghums are the most popular fodder crops in the country. A study was conducted to evaluate the performance of different released fodder genotypes viz., Safed Moti (hybrid), SH 825 (hybrid), CSH 20MF (hybrid), CSH24 MF (hybrid), Sudex Chari (hybrid), along with the popular checks viz., SSG-59-3 (variety) and M.P. Chari (variety) for yields and quality. Physical characteristics of genotypes were also studied. Three cuts were taken in all genotypes invariably. Highest green and dry fodder yields were observed in hybrids i.e., CSH 20MF (75 t ha1 ), Safed Moti (73.9 t ha-1) and Sudex chari (72.14 t ha-1). Crude protein per cent was higher in third cut compared to other cuts. Response in terms of green fodder yields, dry matter yields and protein was found significant only upto 120% recommended dose of fertilizers. CSH20MF, Safed Moti and Sudex Chari were the most promising forage sorghum hybrids for this agro-climatic zone with the recommended fertilizer schedule of 120:48:36::N: P2O5 :K2O kg ha-1 .
