Abstract: A field experiment was conducted in clay loam soils of Jagtial, Telangana State during rainy season of 2015 to study the performance of rice under different establishment methods. The experiment was laid down in randomized block design with three replications. Eleven treatments were taken viz. dry or wet seeding with drum seeder at three row spacing i.e, 20, 25 and 30 cm, broadcasting of dry or sprouted seed in puddled soil, transplanting, SRI and MSRI methods. The yield attributes viz. panicles m-2, spikelets panicle-1 and percent filled grains were found to be high in MSRI method with less chaffyness of grains. The grain and straw yield was higher in MSRI method followed by SRI which was 31.5 and 23.4% higher than that in transplanting method, respectively. Drum seeding at 30 cm spacing with wet seed or dry seed registered an increase of 22.1 and 17.8% in yield over conventional transplanting method, respectively. The SPAD meter reading, test weight and harvest index were not influenced by different establishment methods. The nutrient (NPK) uptake was higher in MSRI method followed by SRI method which were superior to transplanting method.
