Abstract: A field experiment was conducted at Agronomy farm, School of Agricultural Science and Rural Development (SASRD), Nagaland University, Medziphema campus during rainy season of the 2014. Twelve weed control treatments were tested in randomized block design replicated thrice. Result showed that growth and yield attributes parameters and weed dynamics were significantly affected and trend of higher production and lower weed dynamics in different growing stages of direct seeded rice was obtained. Among the weed management practices, Bispyribac Sodium salt @ 250 ml/ha POE at 15 DAS+1Hand weeding at 30 DAS was found the best for obtaining higher production (3.25 t/ha) and highest weed control efficiency (91.48) at 50 DAS. Among the weed control practices, Stale seed bed technique followed by Bispyribac Sodium salt @ 250 ml/ha. POE at 15 DAS was found the best for obtaining higher net profit (Rs/ha 34689.5) and Benefit cost ratio (1.40) in different weed management practices under direct seeded rice system
