Weeds are a significant constraint and cost to agricultural production worldwide. Estimates suggest that without weed control, yield losses could range from 29% in wheat to 47% in rice crops. Historically, weed control was achieved manually or mechanically involving some form of soil cultivation. Although this is certainly effective for reducing weed incidence and in providing a suitable seed bed for sowing crops, the mechanical disturbance of soil also has a number of detrimental side-effects, such as increasing the risks of soil erosion and loss of soil organic matter. The same way weeds are major problem under organic management too. And almost 43% of organic growers expressed; low and no cost weed management techniques should be identified for successful practicing of organic farming. Slash weeding is to be done between the plants. Weeds under the base of the plants can be cleaned and put as mulch around the plant base. The weeded materials should be applied as mulch in the ground itself. Stale seed beds, hand and mechanical weeding are the other options available for managing weeds under organic management. Further, effective crop rotation, mixed and intercropping is also essential for reducing the weeds.
