Abstract: A field experiment was conducted during winter at Regional Research Station, BCKV, Chakdaha of West Bengal with eight - weed control treatments viz. four different doses of 2, 4 - D EE 80 per cent EC @ 0.225, 0.450, 0.675 and 0.900 a.i. kg ha-1, 2, 4-D EE 38 per cent EC @0.450 a.i. kg ha-1, Metsulfuron methyl 20 per cent WP@ 0.004 a.i. kg ha-1, hand weeding twice at 25 and 45 DAS and unweeded control - in a randomized block design replicated thrice. The post emergence application of 2, 4-D EE 80 per cent EC @ 0.900 a.i. kg ha-1 - resulted in effective weed control, recording the least weed density and weed dry weight among the chemical weed control treatments. Hand weeding twice produced highest grain yield followed by 2, 4-D EE 80 per cent EC @ 0.900 a.i. kg ha-1. No phytotoxicity symptoms were observed throughout the observations.
