This review paper focuses specifically allelopathic effects of agriculture land associated plants on the different developmental stages of wheat crop. As wheat is the major cereal crop of the world, its yield per acre is adversely affected owing to allelopathic interactions. Allelopathy is a biological phenomenon by which a plant produces one or morebiochemicals that influence the germination, growth, survival, and reproduction of other plants. These biochemicals are known asallelochemicals and can have beneficial (positive allelopathy) or detrimental (negative Allelopathy) effects on the target plants and the community. Allelochemicals with negative allelopathic effects are an important part of plant defense against herbivory. Allelopathic effects of weeds and agriculture land associated trees were surveyed through literature review. As weeds are part and parcel of every growing crop and these definitely influence the yield per acre of wheat crop. Similarly a large number of deciduous trees grow along the borders of wheat lands. Wheat crop is usually cultivated in winter season in which maximum leaf fall occurs and allelochemicals of leaves affect negatively wheat crop production.
