Abstract
A field experiment was conducted at the Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, U.P. (India), during the Kharif (rainy) season of 2022. The experiment was laid out in a randomized block design with three replications and eight treatments to identify the ideal rate of herbicide for optimum weed control in soybean. Among the herbicidal treatments, the application of haloxyfop-R-methyl 10.5% w/w EC (BCSPL sample) at the rate of 164.1 g/ha as PoE 20 days after sowing (DAS) was found effective in controlling a broad spectrum of weeds with minimum dry weight of weeds and highest mean weed control efficiency (48%) among all the treatments. The same treatment also recorded the maximum seed yield (1.50 t/ha), net monetary return ( 50149/ha), and the benefit-cost ratio (1.37) and thus, found to be an economically viable approach to control diverse weed flora in soybean.
