Abstract:The chemical control, with herbicides, of broad leaf weeds is difficult during the growing period because vetch plants have to compete with weeds during the crop’s growing period.This research was carried outto study the allopathic effects of crop residue on weed control in vetch crops. The experiment was conducted in the city of Shoushtar, Iran. The treatments in the vetch plots were;no weed control, two-step weed control with hand weeding, chemical weed control and applications of crop residue at levels of 3 and 5 tons per hectare. The experiment was based on a statistical design asa randomized complete block design in three replications.The specific weeds under observation were Euphorbia spp, Centaura depressa, Malva neglecta, and Xanthium strumariumand the assessment included determination of the number of vetch plants per unit area, number and the fresh weight of weeds and crop yields of vetch.The results showed that between treatments in terms of number of plants per unit area there was no significant difference, however crop residue on weed emergence and growth had a deterrent effect.The data means indicated thathand weeding had significant differences when compared to other treatmentsand hand weeding increased productivity by 190 percent compared to the control (no treatment).The amount of 5 tons per hectare of wheat residue had a significant effect on number of weed Malva neglecta and Xanthium strumariumand weed fresh weight, at 50%, 54.2%, 57% and 52% respectively
