Abstract: A field experiment was conducted at Bikaner to evaluate the effect of integrated nutrient management on yield attributes and yield of wheat (Triticum aestivum L) and direct & residual effect of nutrients on succeeding pearl millet during rabi and kharif seasons of 2014-15 and 2015-16. Experiment was laid out in a split plot design with three replications comprising different treatment combinations i.e. control, 50%, 75% and 100% RDF, 50% RDF + FYM (5 t ha-1), 75% RDF + FYM (5 t ha-1), 100% RDF + FYM (5 t ha-1), 50% RDF + FYM (5 t ha-1) + Azotobacter + PSB, 75% RDF + FYM (5 t ha-1) + Azotobacter + PSB and 100% RDF + FYM (5 t ha-1) + Azotobacter + PSB, applied in wheat as main plots and 3 fertility levels (control, 50% and 75% RDF) as sub plot in succeeding pearl millet comprising a total of 30 treatment combinations. Incorporation of 75% RDF + 5 t FYM ha-1 + Azotobacter + PSB in wheat, significantly increased all the yield attributes viz (effective tillers per meter row length, spike length and grains per spike), hence increased grain, straw and biological yields of wheat over control and other treatments, but remained statistically at par with 100% RDF + 5t FYM ha-1 + Azotobacter + PSB. In residual study the yield of pearl millet were significantly higher under all INM treatments applied in preceding wheat over control and 100% RDF. Direct incorporation of fertilizers (i.e. 0, 50% and 75% RDF) to pearl millet also significantly increased the yield attributes (number of effective tilles, ear head length and grain weight per ear head) and yield of pearl millet. On the basis of net returns, an application of 75% RDF + 5 t FYM + Azotobacter + PSB to wheat and 75% RDF to succeeding pearl millet were found superior to all the treatments under wheat-pearl millet cropping system.
