Cotton growth is very slow in the initial stages of its life cycle and row spacing is wider which provides ample space for the growth of different categories of weeds and thus become a source of competition for water as well as nutrients, thereby impeding its growth. Weeds are major constraints that reduce the crop yields since they compete with crop for the nutrients, moisture, light and space. The integration of different weed management practices would be a viable option for broad spectrum weed control and enhancement of cotton productivity. Thus, weed management has several aspects such as physical, mechanical, cultural, chemical and integrated weed management methods. A brief reviewof research accomplishment made at various places on different fields related to this investigation is reviewed in this paper. 收起
