The treatment weedy check (no weeding) recorded significantly higher plant height but achieved significantly poor growth parameters, yield attributing characters, yield and economics. Results revealed that among various weed control measures, hand weeding and chemical weedicides recorded significantly higher number of tillers/m2 , dry weight (g/m2 ), LAI, CGR (g/day/m2 ), weed parameters, number of tillers/m2 , length of panicle (cm), number of grains/panicle, 1000-grain weight (g), grain and straw yield (q/ha) and harvest index than weedy check treatment with at par response among themselves. However, chemical weed control practices fetched significantly higher yield and at par net return and B : C ratio as compared to hand weeding (twice) treatment in the experimentation. | Herbicides weed management effect on weed dynamics, crop growth and yield in rice
