Abstract
Chenopodium album L. is an annual weed of cultivated fields. In order to determine its allelopathic potentials, water soluble leaf extracts at different concentrations (25, 50 and 75 %) were tested on growth and yield related attributes of wheat (Triticum aestivum L.) in a pot culture experiment. Results showed that application of concentrated extracts had detrimental effects on plant height, number of tillers and spike length which corresponded to significantly lower grain yield. However, lower concentration (25 %) of the extract promoted these parameters. Results of this study reported significantly suppressive effects of higher concentrations (50 and 75 %) on plant height of T. aestivum L. corresponding to lower grain yield.
