Abstract: Studies were conducted during kharif seasons, 2017 and 2018 to assess the growth and yield of kharif rice under four establishment methods viz. sowing of dry seeds by drum seeder (M₁), system of rice intensification (M₂), Transplanting by hand operated transplanter (M₃) and conventional transplanting (M₄) under three nutrient management treatments viz. organic management (OM) i.e. 100% RDN through organic sources (N₁), 100% RDF (100:50:50 N: P₂O₅ : K₂O kg ha-1) (N₂), integrated nutrient management (N₃) i.e. 50% RDF + 50 % RDN through organic sources. The maximum plant height, number of leaves m^-2, number of tillers m^-2, dry matter production m^-2, number of panicles m^-2, number of filled grains panicle^-1, panicle length, grain yield and straw yield were recorded under conventional and SRI method of transplanting during both the years of experimentation. Conventional transplanting method increased grain yield (43.42 q ha-1) by 22.76 % over drum seeded rice, respectively; whereas, the latter two treatments remained at par. Application of 100% RDF registered the highest grain yield of 42.23 q ha-1 which was higher by 10.32 % over organic and at par with INM.
