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 to find out the best crop establishment technique and the optimum nitrogen dose for 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 yield of the different establishment techniques were in the order, SRI (52.14 q ha-1) being at par to transplanting (45.43 q ha-1) while lowest yield obtained under direct seeding method (36.82 q ha-1). The highest plant height (86.14 cm), number of effective tillers (464.40 m-2), leaf area index (4.19), dry matter accumulation (1027.5 g), days taken to 50 % flowering (81.20) and maturity (135.51) and B:C ratio (M2N4 - 1:2.10) were recorded in SRI technique except initial plant population which was under direct seeding. Based on the results obtained, it can be concluded that in areas where labour is available and cheap, SRI technique is a better establishment method of rice because it produces more yield and gross monetary economic return than other methods.
