Abstract
A field experiment was conducted during kharif, 2019 at Professor Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad. The experiment done with twelve treatments and three replications. The study was taken to find out which herbicide mixture most effective in controlling of weeds leads to maximum yields with higher benefit cost ratio. The results revealed that, application of herbicide mixture florpyrauxifen-benzyl + cyhalofop-butyl 10% EC 150 g/ha PoE fb hand weeding at 40 days after transplanting (DAT) gave higher yields and net returns with high benefit cost ratio (B: C) which was statistically on par with minimum competitive plot. Unweeded plot yield was deviated about 48 % compare to florpyrauxifen-benzyl + cyhalofop-butyl 10% EC 150 g/ha PoE fb hand weeding at 40 days after transplanting.
Keywords: Economics, grain yield, herbicide mixtures, net returns, straw yield, transplanted rice.
