In order to elucidate the allelopathic effects of wheat (Triticum aestivum L.) and Barely (Hordeum vulgar L.) on emergence and seedling growth of some weed species (Rumex crispus L., Datora stramonium L., Sisiymbrium irio L., Dausus carota L., Peganum harmala L., Cardaria draba L., Hordeum spontaneum L., Avena ludoviciana L., Chenopodium album L., Plantago lanceolata L., and Amaranthus retroflexus L.) under field condition an experiment was carried out as RCB design with three replications at Research Farm of the Faculty of Agriculture, University of Tabriz, Iran. Results showed H. spontaneum and S. riro have stimulatory effect on emergence percentage of wheat. However, these weeds species have inhibitory effect on EP of barley. Means root length of wheat by beside of H. spontaneum and A. ludoviciana were increased. However, root length of barley by beside of these weeds was significantly affected and reduced. Seedling of wheat has inhibitory effect on fresh weight of root of H. spontaneum. But, barley has stimulatory effect on this weed specie. D. stramonium by neighboring of wheat has the lowest shoot fresh weight. In contrast, SFW of this weed specie was improved by beside of barley seedling. Also, seedling of H. spontaneum and C. draba in the presence of wheat was produced the lowest root dry weight. Therefore, the response of wheat and barley were differently against the allelopathic material of weed species. In contrast, these crops had various effects on those weeds.
