Abstract

Long-term sustainability is the major concern in the scenario of today’s agriculture. Continuous use of suboptimal doses of nutrients in intensive cropping system has resulted in severe depletion of nutrient reserves in soil, leading to multiple nutrient deficiencies. Combined use of organic and chemical fertilizers significantly improved crop yield and soil physical properties over the recommended dose of inorganic fertilizers alone. A field experiment was conducted at research farm of Bihar Agricultural University, Sabour, Bhagalpur during the rabi season of 2020-21 in a randomized block design with eleven treatments and three replications using three sources of organic manure that were farm yard manure (FYM), wheat straw, green manure (GM) to study the impact of variable integrated nutrient management (INM) in rice (Oryza sativa) and application of inorganic nutrient in wheat on protein content and protein yield of wheat (Triticum aestivum). The results revealed that grai

Conclusion

Integrated nutrient management is an approach that seeks to increase crop productivity without compromising the quality of the produce and thereby help to meet future food demands. Therefore, from long term experiment of 36 years it may be concluded that substitution of 50% inorganic N by FYM and application of 50% RDF in rice followed by 100% RDF in wheat may be adopted for achieving higher productivity, protein content and protein yield in ricewheat cropping system.
