Abstract
The present experiment entitled “To study the effect of integrated weed management practices on weeds parameters of transplanted rice in Chhattisgarh plains” was studied during the 2022, kharif season at Agricultural Research Farm BTC, CARS, Bilaspur, Chhattisgarh. A randomized block design with ten treatments and three replications was used. Treatment T5 (untreated control) had the highest weed density and dry weight measurements, whereas treatment T6 (weed-free) had the lowest.The weed index was lowest in T6 (weed-free). The stage with the highest percentage of weed control efficiency was T6 (Weed-Free), then T10 (Chlorimuron ethyl 10% WP + Metsulfuron methyl 10% WP @ 0.06g ha-1 (20 DAT) + mechanical weeding (20 & 40 DAT) by Ambika paddy weeder at all stages.
