EFFECTS OF HERBICIDES ON THE GROWTH AND YIELD OF WHEAT

Abstract

A field trial was conducted at the Regional Station, Bangladesh Wheat and Maize Research Institute (BWMRI), Rajshahi during winter season of 2023-24 to select the suitable herbicide for weed control on wheat. Nine treatments with BARI Gom 33 was used in this experimental as RCB design. Four major weeds were observed in the experimental field. The weed population and dry weight of weeds were low with Hammer 24 EC and high with control plot. The lowest dry weight of weed was found from Hammer at 35 DAS application.  Among the treatments Hammer 24 EC showed higher weed control efficiency which was at par with Council WG and Hand weeding. Maximum grain yield was obtained from hand weeding which was as par with Council WG and Hammer 24 EC. The lowest grain yield was found from control treatment as anticipated. On the other hand, Council WG as per with Hammer 24 EC was economically suitable for the control of weeds comparatively with less cost. Therefore, according to weed control efficiency and economic benefits, Hammer 24 EC and Council 15 WG at 25 DAS application were found as the best herbicides for weeds control in the wheat field of Rajshahi region.
