Abstract: A field experiment was conducted in Vertisols at Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya. Raipur (Chhattisgarh) to study the effect of rice straw management and nitrogen scheduling on yield, harvest index and economics of summer rice. Results indicated that incorporation of rice straw 5 t ha-1 by MB plough once + disc harrowing twice FB irrigation at 30 DBT (T3) registered significantly highest grain, straw yields, Gross return and net return it was at par to incorporation of rice straw 5 t ha-1 by + disc harrowing twice FB irrigation at 30 DBT (T2). Its Harvest index (%) and B/C ratio is non-significant. Among nitrogen scheduling, treatment 20% B + 20% 15 DAT + 30% AT + 30% PI (N3) recorded significantly highest grain yield, Harvest Index (%), Gross return and Net return of summer rice, although it was at par to 10% B + 20% 15 DAT + 30% AT + 30% PI + 10% F (N4).
