A field experiment was conducted for two years during kharif season of 2017 and 2018 at Agronomy research Farm, N.D. University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) on sandy loam soil with a pH of 8.1 to study the Influence of planting geometry and nitrogen levels on rice (Oryza sativa L.)”. The experiment was laid out in split plot design (SPD) with three replications Sixteen treatment combinations; comprised of four planting geometry, viz. (S1) 15x10 cm, 15x15 (S2),20x10 (S3) and 20x15 (S4) were kept in main plot and four nitrogen level, viz. 0kg/ha (N0), 60 kg/ha (N1), 120 kg/ha (N2) and 180 kg/ha (N3) were kept in sub plot. Under different treatments (planting geometry and nitrogen level) higher number of panicles with the value of 289.7 and 295.4 were recorded in planting geometry of 20x10cm which was at par with 15×15cm spacing while significant over rest both of the treatments while under nitrogen level higher number of panicles by 299.0 and 304.9 were recorded during 2017 and 2018 year of investigation respectively which was at par with 120 kg N/ ha while significant over control and 60 kg N/ha. Whereas highest grain yield of 39.5 q/ha and 46.5 q/ha was recorded during 2017 and 2018 year respectively with planting geometry of 20×10cm spacing which was at par with 15×15cm spacing while significant over rest both of the treatments.
