Abstract: An experiment was directed to assess the effect of integrated weed management practices on weed density and dry biomass in rose cv. Gruss-en-Tepltiz by using treatments paddy straw mulch 0.6 kg/m2, paddy straw mulch 1.2 kg/m2, oxyfluorfen 0.025 g/m2, oxyfluorfen 0.025 g/m2 + paddy straw mulch 0.6 kg/m2, oxyfluorfen 0.025 g/m2 + paddy straw mulch 1.2 kg/m2, hand weeding (at monthly interval) and unweeded control. The least value of weed count of diverse species was recorded in hand weeding closely followed by oxyfluorfen 0.025 g/m2 + paddy straw mulch 1.2 kg/m2. Dry biomass of weeds and weed control efficiency was also marked to be lowest in hand weeding followed by oxyfluorfen 0.025 g/m2 + paddy straw mulch 1.2 kg/m2. Since hand weeding is costly, tedious, laborious, and if not done legitimately, harms the plant and root system, the result of the study advocated using oxyfluorfen in combination with paddy straw mulch at a rate of 1.2 kg/m2 for effectively reducing weed growth.
