The aim of this investigation was to prepare and evaluate organic manures and mineral fertilizers with biofertilizer on crop productivity and changes in soil organic carbon (SOC) and nutrient content under a wheat crop. The results demonstrated that the addition of 100% NPK + FYM + PSB + Azotobactor+ Zn + Fe + Mn recorded significantly higher value of growth, yield attributes and micro nutrient content in grain and straw of wheat, plant height (cm), dry matter accumulation (g m-1), grain, straw, biological yield. Higher grain yield was recorded (58.40 q ha-1) followed by 125% NPK + Zn + Mn grain yield (57.9 q ha-1). The available of nitrogen, phosphorus, potassium and micro nutrients (Zn, Fe, Mn) in soil after harvest of crop and content of micronutrinets in grain and straw increase with the combined application of organic and inorganic with biofertilizer. Integration of 100% NPK + FYM + Azotobactor + Zn + Mn + Fe was found more productivity and remvaerative with the higher residual soil fertility status after harvest of wheat crop. Plots amended with manures and 100% NPK + Azotobactor + Zn + Mn + Fe had pronounced impact on improving SOC and nutrient content after the wheat crop indicating that integrated use of manures and mineral fertilizers could be followed to improve and maintain soil fertility, increase crop productivity under intensive cropping system.
