Abstract: Delay in transplanting rice affects the agronomic characteristics including the growth duration, photosynthetic productivity and dry matter remobilization efficiency which affects the yield attributes like no: of panicles, no: of filled spikelets etc., and finally the grain yield. To identify the best establishment method, variety and nitrogen dosage under late sown conditions, a field experiment was carried out during kharif, 2017 on clay loam soil at Regional Agricultural Research Station, Polasa, Jagtial, Telangana. The experiment was laid out in a split plot design with three replications and twelve treatments with three main plots viz., M₁: Sowing of nursery (July 20^th) and transplanting of seedlings at 25 DAS (August 16^th), M₂: Direct seeding by Broadcasting on August 16^th, M₃: Direct seeding by Drum seeder on August 16^th and four subplots viz., S₁: RNR-15048 with 100% Recommended N, S₂: RNR-15048 with 150% Recommended N, S₃: JGL-18047 with 100% Recommended N and S₄: JGL-18047 with 150% Recommended N.Higher number of spikelets panicle^-1, number of filled grains panicle^-1 and lower spikelet sterility percentage recorded with direct seeding with drum seeder. Significantly higher total number of spikelets panicle^-1, number of filled grains panicle^-1 and spikelet sterility were recorded with RNR-15048 at both levels of nitrogen over JGL-18047. Test weight was not significantly influenced by different crop establishment methods. It was significantly higher in JGL-18047 over RNR-15048 at both levels of nitrogen. Quality parameters were not significantly influenced by the different crop establishment methods. Between varieties, JGL-18047 recorded significantly higher hulling, milling and head rice recovery percentage over RNR-15048 at both levels of nitrogen.
