Presence of diverse weed flora during critical period of crop-weed competition, is one of the major obstacles in conservation agriculture that reduces which can reduce the crop yield appreciably significantly. During critical period of crop-weed competition, chemical method of weed control is by far the most preferred way to minimize the weed infestation of weeds, farmers are mostly relying on chemical methods of weed management. However, its continuous and over use of herbicide has led leads to resistance, and it’s as well as the persistence in soil bore a negative effect on crops singly and in rotation. of herbicides, this may affect the crops in rotation. Conservation agriculture emphasizes on preserving the resources and discourages the use of chemicals. Weeds are controlled in conservation agriculture system through Crop rotation, selection of suitable varieties with optimum seed rate, tillage with proper land levelling, cover crop and proper water management are the options under conservation agriculture. But for a However, an efficient, ecofriendly and economically viable strategy warrants an integrated approach to manage the weed menace. The article attempts to take a stock of available research work on various aspects. proper weed control under conservation agriculture should be integration of these different practices. So, implement the Integrated Weed Management (IWM) in conservation agriculture is highly recommended. IWM plays as a key component in CA systems. For this, compatible, viable, economic and eco-friendly weed management practices should be integrated in a harmonious manner to control the weeds in conservation agriculture. The multiple weed management practices include preventive method, physical method, cultural method, biological method and chemical method.
