The twelve different weed management practices were laid out in randomized block design with three replications. Rice variety “MTU-1010” was grown as a test crop. Rice was transplanted with a spacing of 20 x 20 cm and fertilized with 90, 60 and 40 kg/N, P and K/ha, respectively. At later period of growth, maximum panicle length, number of seeds/panicle, WCE, weed density, dry matter accumulation under post-emergence fb post-emergence application of fenoxaprop-p-ethy (60 g/ha) + ethoxysulfuron (15 g/ha) favoured significant enhancement in seed yield which was at par with hand weeding. Application of postemergence fb post-emergence application of fenoxaprop-p-ethyl (60 g/ha) + ethoxysulfuron (15 g/ha) gave higher net return (Rs 3,4249.72/ha) and benefit: cost ratio (1.72)
