Abstract

A field experiment was conducted during rabi, season of 2016-17 at Crop Research Station, Masodha, Ayodhya (U.P.). The experiment consisting of Eleven treatments was laid out in randomized block design with three replications. The crop was infested with the divergent type of weed flora e.g. Phalaris minor, Fumaria parviflora and Cynodondactylon of grassy, Chenopodium album, Convonvulus arvensis, Anagallis arvensis, Melilotus alba and Solanum nigrum of broad-leaved and Cyperus rotundus, Cyprus iria and Cyprus difformis of sedges group. The sowing of wheat variety NW-5054 (Narendra wheat 5054) was done on 22th November 2016, and harvesting was done on 10th April, 2017. The results revealed that Metsulfuron + Carfentrazone @ 4 + 20 g ha-1 and Halauxifen-methyl Ester +Florasulam 40.85% WG + Polyglycol 26-2N @ 12.76 g ha-1 gave higher weed control efficiency (85.51%, 84.30%), lower weed index (3.75%, 5.85%) respectively. Among of all treatments recorded higest Benefit Cast ratio i

Keywords

Benefit-cost ratio, post-emergence herbicides application, total weed density, weed control efficiency and weed index.

Conclusion

Based on the results obtained from this research that application of Metsulfuron + Carfentrazone @ 4 + 20 g ha-1 followed by post emergence application of Halauxifen - methyl ester + Florasulam + Polyglycol @ 12.76 g ha-1 30 DAS was the best herbicide combination and can be recommended for wheat in enhancing grain yield in terms of lower weed population, lower weed dry matter, high weed control efficiency and low in weed index ultimately resulting in higher benefit cost ratio.
