A field experiment was conducted to evaluate suitable varieties (CSH-5, GFS-4 and Local gundari) of rainfed sorghum and their nutritional (nitrogenous) requirement (four levels: 0, 25, 50 and 75 kg N/na) on medium black clayey soils during Kharif 1991 to 1995. On the basis of pooled results of 5 years, it is concluded that about 18% and 15% higher green fodder yield was recorded with var. CSH-5 and local gundari respectively as compared to var. GFS-4. The green fodder production increased with increase in N application. Significantly the highest yield (162.0 q/ha) and net ICBR (1:2.11) were obtained when the N was applied @ 50 kg/ha. Crude protein content in dry fodder remained unaffected due to different levels of applied nitrogen.
