Brassica juncea is the third important oilseed crop in the world after soybean and oilpalm. In India, as mustard is exclusively grown under irrigated conditions, problem of weeds poses a serious threat to its potential production. Among the factors responsible for low productivity of Indian mustard, poor weed management ranged from 10–58% yield loss (Banga and Yadav 2001). Weed management is necessary to achieve higher yield as weeds compete for water, nutrients, light, oxygen and carbon dioxide and space. At present, hand weeding is the only method employed for controlling weeds in this crop. But most of the farmers of India do not adopt weed management in mustard field, because of unavailability of adequate labour at peak period of crop weeds competition and rising in labour wages. Manual weeding is effective but, it is cumbersome, time consuming and uneconomical. Herbicide would be one of the possible options to minimize weed menace, and may also increase the profit, better weed control and save time and labour. Hence, keeping in view above considerations, the present study was undertaken to study the effect of weed management on weed dynamics and yield of mustard.
