Abstract: The field experiment was conducted at CRC Farm Chirrori, SardarVallabhbhai Patel Agriculture University Meerut during rabi 2011-12 and 2012-13. To study the integrated nutrient management for sustainable wheat production in western U.P. Addition of 100% NPK (RDF-recommended dose of fertilizer i.e 120, 60, 40 kg NPK ha^-1 was recorded significantly higher value of yield and yield attributes in terms of spikelet’s spike^-1, spike length (cm), 1000-grain weight (g), harvest index (%), biological yield and grain yield (q ha^-1) in grain (41.50 and 43.78 q ha^-1) and straw (60.90 and 62.26 q ha^-1) yield followed by 75% NPK + 1 t/ha vermicompost+ Azosprillium which is in grain (41.08 and 42.36 q ha^-1) and straw (60.42 and 60.90 q ha^-1) yield. Available nitrogen content is also increased compared with its soil status under this treatment (75% NPK+1 t/ha vermicompost+ Azosprillium). The content of organic carbon and available NPK in soil after harvest is increase with the combined application of organic and inorganic with biofertilizer. Integrating of 75% NPK + 1 t/ha vermicompost+ Azosprillium found more productivity, and monetary return by maintain or improving the residual soil fertility status after the harvest of wheat crop.
