Planting mixture of cover crops can optimize the benefits of their use. Therefore, in a field experiment the effects of cover crop monoculture and polyculture on weed control of tomato were investigated in Varamin Research Station from 2004-2005. The experiment had a split plot design in a complete randomized block form with three replication. Supplemental weed control were consider as the main factor with two levels (weeding and weedy) and different mixture of rye and hairy vetch (100% rye, 25% rye + 75% hairy vetch, 17/5% rye + 82/5% hairy vetch, 10% rye + 90% hairy vetch and 100% hairy vetch) were placed in subplots. For comparison three control treatments (weeding, weedy and metribuzin herbicide) were placed in the two side of experiment. Biomass of rye and cover crop mixtures were higher than hairy vetch monoculture. Fruit yield was similar in the hairy vetch monoculture and all mixtures but was lower in the rye monoculture in the first year. In the second year fruit yield of all cover crops treatments was similar. Cover crop mixture reduced weed density and biomass compared to vetch monoculture in the first year, but in the second year weed control of all cover crops treatments was similar. Tomato grown in the cover crops without weeding yielded lower than the corresponding treatments with weeding. Cover crops with increasing number of fruit on plant increased tomato yield.
