Integrated effect of organic, inorganic and biofertilizers on crop yield and N,P and K uptake under rainfed maize-wheat cropping system and available nutrients during 2015-2016 is being studied in sandy loam at Jammu under the INM maize-wheat trial. The results revealed that the application of recommended levels of NPK to maize-wheat with FYM, VC and biofertilizers (Azotobacter and phosphate solubilizing bacteria) resulted in grain 66.53 per cent and straw 13.00 per cent increase over control in maize and wheat yields, respectively. Increasing levels of 50% N + recom. P + K + S + Zn + B +Vermicompost +Azotobactera + Phosphorus Solubilizing Bacteria significantly increased the yield of both the crops. Integrated use of organic, inorganic and biofertilizers improved the soil status of available N, P, K, S, (116.09, 14.22, 124.61, 9.41kg ha-1), Zn and B (0.56 and 0.48mg kg-1), over the initial values. A declining trend (N 70.05, P 9.14, K110.13, S 8.14 kg ha-1 Zn 0.36 mg kg-1and 0.34 kg ha-1) from the initial value of available nutrients. Increasing level of total uptake in maize N, P, K, S, Zn and B. This indicates a considerable mining of INM from the soil and suggest the need to adopt judicious organic, inorganic and biofertilizers.
