Abstract
A field study was carried out at college farm of JNKVV, Jabalpur, M.P. to investigate the effect of different weed control treatments on weed flora and soybean. The experiment was laid out in randomized block design with three replications. Nine treatments were comprised of chlorimuron-ethyl 12, 24, 36, 48 and 72 g ha-1, hand weeding, mechanical weeding, combined application of weeding and chlorimuron 24 g ha-1 and lastly weedy check. Application of herbicide and weeding effectively controlled weeds flora and their density rather than weedy check. Among all the treatments hand weeding recorded higher yield attributes, yield (1.69 t ha-1 grain) and net monetary returns (`20011.7 ha-1), but it was at par with chlorimuron-ethyl 24 g/ha along with mechanical weeding, that recorded 1.69 t ha-1 grain yield and `20023.8 ha-1 NMR.
