Field experiments were carried out at Mountain Livestock Research Institute (MLRI), Manasbal, Sher-e-Kashmir University of Agricultural Sciences and Technology Kashmir, India to study the direct and residual effect of different rates of organic and chemical sources of nutrients on fodder sorghum-fodder oat cropping sequence during Kharif 2008, 2009 and rabi 2008-09, 2009-10. Application of FYM @ 25tonnes recorded higher green fodder yield of sorghum than rest of treatments. The physical optimum dose of direct+residual effect of FYM on fodder sorghum-fodder oat sequence was 25.49 t ha-1 and economic optimum dose 12.63 t ha-1. Applying 120, 80 and 30 (N, P2O5, K2O kg ha-1) was found superior in green fodder yield than rest of treatments. However, physical optimum dose due to direct +residual effect of N, P2O5 and K2O on fodder sorghum-fodder oat was 134.19 , 67.07 and 33.54 kg ha-1 and mean total economic optimum dose was found to be 128.0, 64.19 and 32.62 NPK kg ha-1 respectively.
