Abstract

Modern agriculture is productivity oriented and depends mainly on synthetic inputs (herbicides) to manage weeds. However, non-judicious use of these synthetic herbicides could cause environmental, health and herbicides resistance issues. Therefore, a focus has been given since last two decades on the use of plant derived organic substances as alternative to inorganic herbicides for weed control. Allelopathy is an eco-friendly and organic weed management approach, which may be used as a tool in controlling weeds. In this study, allelopathic water extracts of sorghum, sunflower and brassica were applied at 25, 40 and 55 DAS each at 18 and 20 L ha-1 ,for weed management in wheat. For comparison, a standard herbicide i.e. idosulfuron + mesosulfuron (Atlantis) and a weedy check were maintained as control. Reduction in total weed density and biomass by the application of two foliar sprays of tank mixed sorghum, sunflower and brassica each at 18 L ha-1 were 48-59 and 48-58%, respectively. Maximum wheat grain yield was recorded from the application of two foliar sprays of sorghum, sunflower and brassica mixture at 18 L ha-1 at 25 and 40 DAS. This treatment was also economically the most feasible than other crop water extract treatments, with the maximum net benefits. This study suggests that allelopathy offers an attractive and environmental friendly organic method of weed control in wheat.
