A field experiment was conducted at Zonal Agricultural Research Station, Visweswaraiah Canal Farm, Mandya (Karnataka) during Kharif seasons of 2011 and 2012 to study the response of multicut fodder sorghum to different seed rates and nitrogen levels under protective irrigated condition. The experiment consisted of 12 treatments, tested in randomized complete block design with factorial concept replicated three times. The pooled data indicated that seed rate of 7.5 kg/ha recorded significantly higher green fodder (74.10 t/ha), dry matter yield (17.41t/ha) and growth parameters like plant height (150.77 cm), number of tillers per meter row length (73.08), leaf stem ratio (0.25), net returns (Rs. 35018) and B: C ratio (2.40). Among nitrogen levels, application of 30 kg/ha recorded significantly higher green fodder (69.60 t/ha), dry matter yield (15.91 t/ha) and growth parameters like plant height (148.37 cm), number of tillers per meter row length (69.97), leaf stem ratio (0.23), crude protein yield (1.26 t/ha), crude fiber yield (5.34 t/ha), nitrate nitrogen content (1168.06 ppm), net returns (Rs. 31285/ha) and B: C ratio (2.20).
