Intregrated nutrient management for sustainable wheat (Triticum aestivum L.) production in Western Uttar Pradesh

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.
