Effect of Integrated Nutrient Management (INM) in Wheat on Soil Properties and Fertility Status

A field experiment was carried out at research farm of A.S. (P.G.) College, Lakhaoti, Bulandshahar (U.P) to find out the effect of integrated nutrient management applied to wheat (Triticum aestivum L.) on soil properties and fertility status. The result revealed that a significant improvement in soil properties and fertility status was found under treatment (T₂₀) comprising of 100% Rec. NPK + Vermicompost + Zinc + PSB. Organic carbon content of soil improved from 3.0 to 4.6 g/kg soil, Bulk density reduced from 1.50 to 1.32 Mg/m³, water holding capacity increased from 20.32 to 23.72 %, available N from 197.0 to 219.0 kg ha^-1, available P from 13.0 to 19.1 kg /ha^-1, available K from 113.0 to 130.4 kgha^-1 and available Zn from 1.50 to 1.87 mg kg^-1 soil by the integration of organics with inorganics. However, the pH and electrical conductivity of soil were not reflected to a considerable extent.
