Allelopathey is a biological process including interactions between two plants through the production of chemical compounds (allelochemicals) which can diminish weed problems. Both common vetch (Vicia sativa) and rye (Secale cereal) have shown strong allelopathic effects on many weed species. In order to assess the phytotoxic potential of rye and common vetch water extract on corn and some weed species, an experiment was conducted in the Seed Research Laboratory of Razi University, Kermanshah, Iran in 2012. Water extracts of common vetch and ryewere used as pure or mixed. Plant species under study consisted of corn and some weed species including green foxtail, redroot pigweed, lamb's quarters, barnyard grass and common cocklebur which are commonly dominant weeds of corn fields in the region. The results showed that the germination of weed species were completely inhibited by water extracts of rye and common vetch in pure or mixed treatment. Vetch extract did not significantly affect corn germination percentage, whereas, this trait was significantly influenced by rye and mixed treatments as compared with control.
