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

Abstract

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 pendimethalin at 1.0 kglha and fluchloralin at 1.0 or 2.0 kglha 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 un der 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 (1 6.2) and the highest weed control efficiency.
