Abstract : The present investigation was conducted under irrigated condition during 2009-10 at Indira Gandhi Krishi Vishwavidyalaya, Raipur under All India Coordinated Research Project on Integrated Farming Systems with eight treatments. T2 was highly infested by weed at 30 DAT (119 m-2) followed by T3 (116.67 m-2). At 60 DAT, ‘Mahamaya’ and ‘Indira Sona’ were comparatively more infested by weeds to that of early maturing MTU-1010. The maximum grain yield of rice (49.90 q ha-1) was recorded under T4 treatment. The maximum straw yield (67.09 q ha-1) was recorded in T4. The maximum net return (Rs 34,704 ha-1) was obtained from early duration rice ‘MTU-1010 in T3. The maximum B: C ratio (2.01) was recorded in T3 followed by T2 (1.97).
