Abstract
A field experiment on evaluation of weed management practices in scented rice under organic production system was conducted during 2017-18 at All India Coordinated Research Project on Farming System, College of Agriculture, Rewa (M.P.). Fimbristylis dichotoma was the most dominating weed in rice field followed by Jussia suffurusticosa. Incorporation of mustard oil cake at 5 t/ha along with one hand weeding gave maximum weed control efficiency (68%). Growth and development of rice was better with incorporation of mustard oil cake 15 days before sowing 5 t/ha + 1 hand weeding (HW) followed by two HW at 20 and 40 days after transplanting (DAT) and locally available weed mulch Saccharum spontaneam at 3 t/ha + 1 hand weeding . These treatments gave 34 to 56% higher grain yield as compared to farmer’s practice of weed control as mulching with mango leaves. Net profit of ` 62061/ha was maximum in mulching with locally available weeds + 1 hand weeding followed by ` 56695/ha in two HW at 20 and 40 DAT.
