Abstract: A field experiment was conducted at Agronomy Research farm, College of Agriculture, N. D. University of Agriculture and technology, Kumarganj, Faizabad, U.P. during kharif season of 2016-17 to find out the best crop establishment methods and the optimum nitrogen dose for obtaining higher yield of rice. During the experiment, common packages of practices were followed time to time and periodically are observations were recorded on growth and yield for evaluate the treatment effects. The results obtained during the study revealed that grain and straw yield of the different establishment techniques were in the order, SRI method, conventional transplanting method followed by direct seeding method. The highest no. of panicle m^-2 (447.15), length of panicle (21.20 cm), no. of grains panicle^-1 (158.03), test weight (24.60 g), straw yield (61.42 q ha^-1), grain yield (52.14 q ha^-1) and harvest index (45.91%) under SRI method of crop establishment. The nitrogen uptake and its contents in rice (both in grain and straw) were found to be the maximum with SRI method (M₂) while lowest nitrogen uptake and its content contents in rice (both in grain and straw) were found to be with direct seeding method. Among the nitrogen levels tried, the maximum no. of panicle m^-2 (413.30), length of panicle (22.99 cm), no. of grains panicle ^-1 (166.39), test weight (23.97 g), straw yield (60.23 q ha^-1), grain yield (51.25 q ha^-1) and harvest index (45.97%) obtained with application of 160 kg N ha^-1. The nitrogen uptake and its contents in rice (both in grain and straw) were found to be the maximum with application of 160 kg N ha^-1, which was comparable with 120 kg N ha^-1 While, the lowest uptake and its contents in rice (grain and straw) was associated with 0 kg N ha^-1. The highest gross return (Rs. 106698.4), net return (Rs. 72329.7) and B-C ratio (1:2.10) were recorded with M₂N₄ treatment combination (SRI method with application of 160 kg N ha^-1). Based on the results obtained, it can be concluded that SRI method is a better establishment method of rice because it produces more yield and gross monetary economic return with 160 kg N ha^-1 than other methods and nitrogen levels.
