Assessing the Impact of Integrated Nutrient Management Practices on Growth and Yield Performance of Direct Seeded Rice in Dystrudepts of Nagaland

Abstract

Background: Indian agriculture continues to be a gamble with monsoon, Direct seeded rice (DSR) can prove to be a promising method technically and economically, which is an achievable alternative to transplanted rice. On the other hand, the soil has become dilapidated of late due to ill-agricultural practices. Therefore, soil fertility and productivity restoration are in dire need, which can be done through integrated nutrient management. Methods: The investigation was conducted to assess the impact of integrated nutrient management on the growth and yield performance of direct seeded rice in dyrtrudepts of Nagaland at the experimental farm of the School of Agricultural Sciences (SAS), Medziphema Campus, Nagaland University, during kharif season of 2019 and 2020. A randomized Block Design with three replications and twelve treatments was applied for the trial. Result: Application of 100% RDF + 2 t FYM ha-1 + PSB (T5) significantly increased the growth parameters, yield attributes, and yield of direct seeded rice which was at parity with T4 (100% RDF + 2 t FYM ha-1) in both the years of cultivation. Therefore, the integrated use of nutrients favored the growth and yield characteristics of direct-seeded rice.
