Black rice also known “Chakhao” in Manipuri language is unique due to its purplish black colour because of its high anthocyanin content and its multiple health benefits. Weeds are of major concern as they compete severely with black rice and to minimize adverse impact of weeds on black rice, integration of different weed management strategies including competitive cultivars and herbicides are required as components of weed management. Hence a study was conducted with an objective to identify effective integrated weed management method to manage weeds and improve productivity of black rice. The highest growth, yield attributes and yield of black rice was recorded with hand weeding (HW) twice at 15 and 30 days after seeding (DAS) and was closely followed by pre-emergence application (PE) of pretilachlor 1.0 kg/ha followed by (fb) HW at 40 DAS. Among cultivars, Chakhao poireiton and Wairi chakhao recorded maximum and minimum growth, yield attributes and yield, respectively. The lowest weed density, biomass and nutrient depletion was observed with hand weeding twice at 15 and 30 DAS and cultivar Chakhao poireiton which also recorded the highest cost of cultivation and gross returns during both the years.
