Effect of Different Weed Management Practices on Growth, Yield and Quality of Black Gram (Vigna mungo L.) under Irrigated Condition

Abstract

A field experiment was conducted during zaid season of 2023 at Shradhey Bhagwati Singh Agriculture Research Farm (Hajipur), Chandra Bhanu Gupt Krashi Snatakotter Mahavidyalaya, B.K.T, Lucknow (UP) to assess the weed management effect on weeds, crop growth, yield attributes, yield studies, nutrients uptake and economics of black gram. The result of the investigation revealed that two hand weeding at 20 and 40 DAS was found superior in controlling weeds, increasing black gram yield and nutrient uptake and recorded maximum benefit: cost ratio. Among the herbicidal treatments, application of pendimethalin 30 EC @800 g/ha (PE) + one hand weeding at 30 DAS were recorded the lowest weed density, weed dry weight and highest weed control efficiency, growth parameters, yield attributes, yield, quality parameters, net return and B:C ratio in black gram crop
