Abstract
The allelopathic effects of aqueous extract of Cyperus esculentus L. on germination and seedling growth of Cajanus cajan, Phaseolus vulgaris (brown and white varieties) and Sphenotylis stenocarpa were observed. Extract showed significant positive allelopathic effects at P< 0.05 on plumule lengths and radicle lengths. The number of root hairs for C. cajan was only reduced at far higher concentrations. The need for harrowing was also discussed.
