COMPATIBILITY OF DIFFERENT WEED MANAGEMENT PRACTICES ON MAIZE YIELD AT RANGAMATI REGION

An experiment was conducted in the farmers’ field of Ghagra and Kochukhali under Kawkhali upazila at Rangamati district in the Rabi season of 2016 to find out a compatible weed management practice for farmers with the financial help of CRP Hill Agricultural Project (Component-III) by Krishi Gobeshona Foundation (KGF) and technical assistance of Regional Agricultural Research Station, BARI, Hathazari, Chittagong. The experiment was laid out in a randomized complete block design with three replications. Six treatments were selected, e.g., Hand weeding, weed Mulch, Hand weeding + Mulch, Hand hoeing, Weed free and Control. The maize variety was BARI Hybrid Bhutta-9. Minimum weed biomass, Maximum Weed control efficiency (WCE %) and Maximum number of cobs per plant was in weed free condition in case of both Ghagra and Kochukhali. Individual cob wt. (g), 100 grain wt. (g) and Grain yield (kg/ha) was found highest in hand weeding + mulch application in case of both Ghagra (306.68g, 39.65g, 10.02 t/ha) and Kochukhali (310.64g, 37.74g, 9.28 t/ha) respectively. Considering yield and yield contributing characteristics hand weeding + mulch application was found compatible for maize production at Ghagra and Kochukhali under Kawkhali upazila at Rangamati district.
