Abstract:
A field experiment on “evaluation of different herbicides on weed management in wheat (Triticum aestivum L.) under Gorakhpur region’’. was conducted at Crop Research Farm of National Post Graduate College, Barhalganj, Gorakhpur, (U.P.) during rabi season of 2021-22. The experiment comprised of five post emergence herbicides application along with weed free and weed cheek treatments. Maximum weed control efficiency was observed in T2 weed free (20+40 DAS) treatment followed by T6 Sulfosulfuron 75% WG + Metsulfuron-methyl 5% WG 40 g/ha-1, T7 Clodinofop- propargyl 15% + Metsulfuron-methyl 1% WP 400 g/ha-1 (30 DAS), T5 Sulfosulfuron 75% WG 33.3 g/ha (30 DAS) and T4 Metsulfuron-methyl 20% WP 20 g/ha (25 DAS). T6 Sulfosulfuron 75% WG + Metsulfuron-methyl 5% WG 40 g/ha-1 recorded lowest lowest weed index. The minimum weed dry weight was recorded T2 Weed free (20+40 DAS) treatment but was at par treatment with T6 Sulfosulfuron 75% WG + Metuslfuron-methyl 5% WG @ 40 g/ha (25 DAS) and T7 (Clodinofop- propargyl 15% + metsulfuron-methyl 1% WP @ 400 g/h (30 DAS). The maximum grain and straw yield was observed in T2 weed free (20+40 DAS) which was statically at par with that observed with application T6 Sulfosulfuron 75% WG + Metsulfuron-methyl 5% WG 40 g/ha-1 T7 Clodinofop- propargyl 15% + Metsulfuron-methyl 1% WP 400 g/ha-1 (30 DAS), T5 Sulfosulfuron 75% WG 33.3 g/ha (30 DAS) and T4 Metsulfuron-methyl 20% WP 20 g/ha (25 DAS). The lower grain and straw yield was recorded under T1 weedy check which was significantly inferior to rest of the treatments. The harvest index was in the range of 36.08 to 44.99% under different weed control treatments. The maximum gross return of wheat (₹ 1,27,565.95 ha-1) was observed in plots treated with T2 weed free (20+40 DAS), and it was followed by plots T6 Sulfosulfuron 75% WG + Metsulfuron-methyl 5% WG 40 g/ha-1 (₹ 1,25,064.00 ha-1). The maximum net return of wheat (₹89,533.00 ha-1) and benefit ratio (2.51) was observed in plots had plots treated with T6 Sulfosulfuron 75% WG + Metsulfuron-methyl 5% WG 40 g/ha-1, and it was followed by plots T7 Clodinofop-propargyl 15% + Metsulfuron- methyl 1% WP 400 g/ha-1 (₹ 84,781.55 ha-1) and benefit ratio (2.39). The results indicate the application of Sulfosulfuron 75% WG + Metsulfuron-methyl 5% WG 40 g/ha-1 or Clodinofop-propargyl 15% + Metsulfuron-methyl 1% WP 400 g/ha-1 (30 DAS) are most remunerative and effective herbicides for weed management in irrigated wheat under sandy loam soils of eastern Uttar Pradesh.
