Allelopathy, A. cruentus, S. arvensis, S. irio, S. oleraceus, Triticum aestivum, Vicia faba, Chlorophyll content.


Laboratory experiment was conducted in faculty of agriculture, Alexandria University to determine allelopathic effect of four weeds (Amaranthus cruentus, Sinapis arvensis and Sisymbrium irio and Sonchus oleraceus) on two winter crops (Triticum aestivum and Vicia faba). Different concentrations (2.5, 5, 10 and 20%) from the stock solution of leaf extract were used to evaluate its effect on germination, shoot and root length as well as total chlorophyll content of tested crops. The results indicated reduction in all measured parameters especially at higher concentrations. The lower concentration (2.5%) did not affect germination, shoot and root length and chlorophyll content measurements. It was concluded that aqueous leaf extract of the used weeds had allelopathic effect on these crops.
