In order to compare weed control efficiency and the effects of non-living mulches (organic and inorganic) and metribuzin on weed population dynamics in tomato field, research was conducted in a randomized complete block with three replications in the Agriculture College of Shiraz University in 2012. The highest weed control efficiency was related to the clear plastic mulch (% 23.86) that with black plastic mulch (% 23.83) and metribuzin (% 59.84) was not statistically different. The longest average germination time of weeds was seen in plots treated with clear and black plastic mulches. The lowest time of flowering weeds was seen under the influence of weedy treatment and inorganic mulches. Comparison of the average time of weed seed ripening showed that the longest time of weed seed ripening was seen with metribuzin (131.29 days after transfer of the tomato seedling to the main field) that was significantly difference from all mulches treatments.
