The soil of the experimental field was sandy loam with pH 7.5, 0.41% organic carbon, 0.13 dSm -1 electrical conductivity, having available nitrogen 227.6 kg ha - 1 , available phosphorous 13.9 kg ha -1 and available potassium 173.9 kg ha -1 . The experiment comprised 11 treatments, viz., T1-Control, T2-100% NPK (120:60:40 kg ha -1 ), T3-100% NPK+ Zn (5 kg ha -1 ), T4- 100% NPK + Zn + S (25 kg ha -1 ), T5-100% NPK + Zn + S + Azotobactor + PSB, T6-100% NPK + Zn + S + Vermicompost (5.0 t ha -1 ), T7-100% NPK + Zn + S + FYM (5.0 t ha -1 ), T8-100% NPK + Zn + S + Vermicompost (5.0 t ha -1 ) + Azotobactor + PSB, T9-100% NPK + Zn + S + FYM (5.0 t ha -1 ) + Azotobactor + PSB, T10-75% NPK + Zn + S + Vermicompost (10.0 t ha -1 ) + Azotobactor + PSB, T11- 75% NPK + Zn + S + FYM (10.0 t ha -1 ) + Azotobactor + PSB. The experiment was laid out in randomized block design, replicated thrice. The maximum grain yield (4.72 and 4.95 t ha -1 ) were recorded in application of 75% NPK + Zn + S + Vermicompost (10.0 t ha -1 ) + Azotobactor + PSB (T10) was statistically superior over all the treatments except T11 and T8 during both the year. Application of 75% NPK + Zn + S + Vermicompost (10.0 t ha -1 ) + Azotobactor + PSB (T10) recorded higher net return (Rs 57,690 ha -1 and Rs 58,170 ha -1 ) and maximum B:C ratio (1.61:1, 1.58:1) were recorded under 100% NPK + Zn + S + Azotobactor + PSB (T5) during both the years.

Introduction Wheat is grown extensively in Uttar Pradesh as staple food crop and plays a pivotal role in agricultural economy of the state. Crop is crucial for food security and social stability. The productivity of wheat has been stagnant in the state during the last decade and so. In U.P. Wheat is grown under different cropping systems and occupies about 9.5 million ha of area with an average productivity of 3,432 kg ha -1 (Agricultural Statistics at a Glance, 2020). Productivity of wheat is relatively poor in state with narrow profit margins. Under certain situations, cost of cultivation exceeds the net realization, making it an unprofitable. Yield enhancement has been the major agronomical challenge. In order to meet the food demands on a rising population in the first decades of the 21 st century, farmers must manage nutrients and soil fertility in an integrated way. Required yield increases of major crops cannot be attained without ensuring that plants have an adequate, balanced supply of nutrients. The fertilizer consumption in India including U.P. is grossly unbalanced, tilted more towards nitrogen, followed by phosphorus. This has implications on yield response to fertilizer as it decreases the crop quality and adversely affects the overall soil fertility and productivity. Apart from improved varieties and irrigation, limited use of organic manure and imbalance in use of chemical fertilizers leading to the emergence of multiple nutrient deficiencies are major constraints in realizing higher yield. Integration of inorganic and organic sources such as vermicompost, poultry manure, farmyard manure (FYM) and their efficient management has sown promise in sustaining the productivity and soil health besides meeting part of crop nutrient requirement (Chaudhary et al., 2014) [2] . Integrated nutrient management (INM) is an approach that seeks to both increase agricultural production and safeguard the environment for future generations. It is a strategy that incorporates both organic and inorganic plant nutrients to attain higher crop productivity, prevent soil degradation, and thereby help meet future food supply needs.
