Abstract:
The experiment was carried out at the Agricultural Research Farm of National Post Graduate College Barhalganj, Gorakhpur, U.P. During rabi 2022-23. This experiment consisted of one barley variety BH-393 and 7 weed control treatments was laid-out in Randomized Block Design with 3 replications. There were eight main weed species (grassy-2, non-grassy-5 and sedges^-1) in the experimental field. Non-grassy weeds (Anagallis arvensis, Chenopodium album, Melilotus indica, Lathyrus aphaca and Fumaria parviflora) dominated over grassy weeds and sedges. At 30 days after sowing, the weed density and dry weight of weed almost similar under all weed control treatments whereas in later stages weed control treatments reduced the weed density and dry weight of weeds as compared to weedy check. The most effective weed control treatment was T₇.Each weed control treatment proved better than weedy check in enhancing growth, growth attributing characters, and yield attributing characters. The highest net returns were recorded under T₆ (sulfosulfuron 30 DAS + 2,4-D 40 DAS) and T₄ (sulfosulfuron 30 DAS), respectively.
