In laboratory and greenhouse studies, the aqueous extracts of Xanthium strumarium L. drastically inhibited the germination and seedling growth of mung bean. Mungbean plumules were less sensitive to allelopathic effects than radicles. Increasing concentrations of extract severely inhibited the shoot growth. Comparison to soil incorporated dry mix (root, stem, leaf and flowers) residues, the soil surface applied dry mix residues drastically inhibited the mungbean germination and seedling growth in pots. This study indicated that cocklebur had a clear allelopathic effect on mungbean germination and seedling growth even though the extent of inhibition was severe under laboratory than greenhouse conditions. From practical point of view, the identification of weeds with potential pool of allelochemicals and characterization of their adverse effects on germination and retarded growth of crops during early development stages and finally on the commercial yield is highly recommended.
