Abstract: Allelopathy is a naturally occurring ecological phenomenon of interference among different crops. Waste-land weeds are present all around the field and hamper the germination and growth of crops. They also compete with crops and reduced the seedling development processes of various crops through the production and release various allelochemicals. These chemicals may inhibit or support the germination and development of neighboring plants. Various weeds like Parthenium hysterophorous L., Achyranthes aspera L., Lantana camara L. and Withania somnifera L. grown at waste-lands and create problems during the crop germination and reduced efficiency of farm practices. In this review we will discuss the phytotoxic effect of various waste-land weeds on performance of germinating seed through its leachates and rhizospheric soils.
