Integrated plant nutrition management system is one of the best methods of plant nutrition, which enhances the farm productivity. To evaluate the effect of organic and mineral nutrition on wheat production, a field study was conducted at Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut. The experiment was arranged according to Randomized Block Design in three replications with fourteen treatments viz.; T1- Control, T2- 100 % NPK, T3-75 % NPK + FYM, T4- 75 % NPK + FYM + PSB+ Azotobactor, T5- 100 % NPK + Zn, T6- 100 % NPK + Zn+ Mn, T7-100 % NPK + Zn + Mn + Fe, T8-75 % NPK + FYM+ PSB+ Azotobactor + Zn + Fe + Mn, T9-125 % NPK, T10- 125% NPK + Zn, T11- 125 % NPK + Zn+ Mn, T12-125% NPK + Zn + Mn + Fe, T13-100% NPK + FYM+ PSB+ Azotobactor + Zn + Fe + Mn and T14-50% N +100%PK + FYM+ PSB+ Azotobactor + Zn + Fe + Mn + LCC based N top dressing. The results revealed that the addition of 100% NPK + FYM + PSB + Azotobactor+ Zn + Fe + Mn recorded significantly higher value of growth, yield attributes and nutrient uptake in terms of plant height (cm), dry matter accumulation (g m-1), number of effective tillers (m-2), 1000-grain weight (g), protein content (%) and grain yield (58.40 q ha-1) followed by 125% NPK + Zn + Mn grain yield (57.9 q ha-1). The total uptake of nitrogen, phosphorus, potassium and micro nutrients (Zn, Fe, Mn) and content of organic carbon 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 wheat crop. The integration of mineral fertilizers with FYM not only escalated the grain yield of wheat but also enhanced micro nutrients uptakes and their recoveries over mineral fertilizer alone.
