Abstract

The prognosis of increasing water scarcity under climate crisis and escalation of labor shortages in agriculture have brought a paradigm swing in rice cultivation from conventionally flooded transplanting to direct-seeded rice. Furthermore, rice being an exhaustive crop leads to nutrient depletion. Therefore, integrated nutrient management can be an effective way to sustain soil health and increase in crop productivity. This study evaluates the impact of INM practices on the performance of direct seeded rice in terms of economic, nutrient content and uptake at the experimental farm of School of Agricultural Sciences and Rural Development, Nagaland University in Randomized Block Design with 3 replications and 12 treatments during the kharif season of 2019 and 2020. Higher nutrient content and uptake by grains and straw was observed T5 (100% RDF + FYM @ 2 t ha-1 + PSB) followed by T4 which showed parity with each other and significantly higher than the rest of the treatments. Significantly minimum value was noted in T1 (Control). Furthermore, integrated application of nutrients (T5) fetched maximum gross return, net return and B:C ratio.

INM, nutrient content, nutrient uptake, economic, direct seeded rice

Conclusion

The outcome of the study disclosed that T5 (100% RDF + FYM @ 2 t ha-1 + PSB) recorded higher nutrient content and uptake as well as higher profitability during both the years of investigation. Therefore, it can be concluded that integrated nutrient management has emerged as a solution to degraded soil fertility and sustainable crop production.
