A field experiments was conducted at Division of Agronomy, SKUAST-K from 2006 to 2009 to compare FYM, Bio fertilizers and Crop residue alone and their integration with chemical fertilizers in rice-wheat cropping system under temperate Kashmir valley conditions. The treatments comprised of two standard controls i.e. (1) recommended fertilizer dose (120:60:30 kg/ha of N:P2O5:K2O) and (2) no manuring along with 8 eight organic resources. Among the nutrient sources, grain yield of rice, wheat, rice equivalent wheat and rice equivalent system yield were recorded statistically higher with 100% RDF followed by FYM @ 25 t/ha + biofertilizers and FYM @ 20 t/ha + biofertilizers which were at par with each other. Lowest yield was recorded in no manuring treated plots. All the yield attributes registered increasing trend but Net return and benefit cost ratio was reduced with application of FYM and crop residue due to high input cost.
