A field experiment was conducted in 2015-16 at Akola (MS) to find out the impacts of in-situ enhanced straw decomposition on soybean yield and economics. It was laid into the Randomized Block design with 4 replications where 5 treatment combinations made for nutrient management through combining the inorganic fertilizer, straw application with and without Trichoderma viride application. The study revealed that Yield attributes, grain yield, straw yield, GMR and B:C ratio was significantly improved with application of RDF through chemical fertilizers. But, the application of 75% RDN + 25% N through soybean straw + T. viride also improved all parameters equally. So, it could be concluded that application of 75% RDN + 25% N through soybean straw + T. viride proved to be the most feasible system of integrated nutrient management and the application of decomposition enhancer, i.e. Trichoderma viride posses the potential to replace the source of nitrogen.
