A field experiments on evaluation of weed management practices in scented rice under organic production system was conducted during 2017-18 and 2018-19 at All India Coordinated Research Project on Farming System, Rewa (M.P). The study reveals that weed control efficiency and grain yield of rice were maximum under incorporation of mustard oil cake 5 t/ha+1 HW and two hand weeding at 25 and 50 DAT. The net profit and B:C ratio were maximum under 2 HW at 25 and 50 DAT followed by mulching with
