Effect of integrated nutrient management on growth and yield of local rice (Oryza sativa L.) under rainfed upland condition of Nagaland

An investigation to assess the “Integrated nutrient management in local rice (Oryza sativa L.) Cultivars under rainfed upland condition of Nagaland” was carried out at School of Agricultural Sciences and Rural Development, Nagaland University, Medziphema, Nagaland, during kharif season of 2015. This experimentation was carried out under factorial randomized block design (FRBD) based on three replications with 10 treatments. The factors comprised of two local rice cultivars viz. Nyakmok (V1) and Jamaghu (V2) and five fertilizer doses. The results revealed that, the application of 100% RDF + 5 t ha-1 FYM enhanced the growth and yield of both the local rice cultivars. The application of 100% RDF + 5 t ha-1 FYM recorded highest number of panicles m-2 (120), length of panicle (28.93 cm), test weight (30.55 g), grain yield (3140.28 kg ha-1) and straw yield (8888.89 kg ha-1). Combination of cultivar ‘Nyakmok’ with the application of 100% RDF resulted in significantly highest harvest index (32.68 %), uptake of P (19.93 kg ha-1) and K (56.83 kg ha-1). It is concluded from the study that Cultivar ‘Nyakmok’ was more suitable with 100% RDF + 5 t ha-1 FYM under rainfed upland condition of Nagaland.
