Agricultural crop production is always under threat of different of environmental challenges which leads to decline crop productivity to a significant extent , among various factors weeds are the most notorious agent, that not only cause drastic decline the crop production in major crops but also effect negatively on soil health too. Since, there is a continuous pressure of growing population to cope with inflating need of food demand. There is a constant need to identify the area to address the weed mediated decline in crop production. Allelopathy could be a most promising tool for sustainable agricultural production, by suppressing the weed growth and prevention of weed resistance to toxic chemical herbicides. Variety of different classes of allelochemicals are identified and assayed for their allelopathic potential, either alone or as combinations with chemical herbicides. Majority of allelochemicals are secondary metabolites and belongs to different chemical families. Allelochemicals exhibit their effect by targeting important physiological and biochemical processes of plants. Identification of suitable allelochemicals will not only help to develop natural herbicide but also reduce dependence on chemical herbicides. Allelopathic potential is identified in various food as well forage crops like sorghum, oat, alfalfa, rye, rice sunflower, wheat, beet, etc. that can be exploited for weed control in agricultural system very effectively. Variety of different agricultural practices can be adopted for sustainable weed management and agricultural crop production by using the allelopathic crops. Agricultural practices like mulching, intercropping, crop rotation, smoother crops, crop covers and green manures etc. proved to be the better practices towards better weed managements and increased the crop production. Therefore, present review focus on different dimensions of crop allelopathy and its potential as a most sought green technology towards weed management and sustainable agriculture production.
