Integrated weed management in capsicum (Capsicum annuum) under mid-hill conditions of north-western Himalayas

A field experiment was conducted at Experimental Farm, Hawalbagh, Vivekananda Parvatiya Krishi Anusandhan Sansthan, Almora, during 1997 and 1998, to evaluate the efficacy of integrated weed-control method in capsicum (Capsicum annuum L). All the weed-control treatments except pendimethalm at 1.0 kg/ha and fluchloralin at 1.0 or 2.0 kg/ha significantly reduced weed density and weed biomass which in turn increased yield significantly compared with weedy check in both the years. The highest fruit yield of 201.3 q/ha was recorded under repeated weeding. Among the herbicidal treatments, application of alachlor at 3.0 kg/ha, followed by hand-weeding at 45 days after transplanting proved the best in terms of yield (168.5 q/ha), net returns (Rs 73, 326/ha), the lowest weed index (16.2) and the highest weed-control efficiency.
