Effect of Novel Herbicides and Herbicide Mixtures on Yield and Economics of Transplanted Rice

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.

Yield and Economics as Influenced by Irrigation and Weed Management Practices in Rice

“…Among weed management practices higher cost in hand weeding treatment due to high labor costs for manual weeding and in IWMS involving preemeregent herbicides fb mechanical weeding twice due to cost of herbicides and fuel and labour involved in operating mechanical weeding. Similar findings were reported by Venkatesh [14].…”
