Abstract

The current study, was designed in a randomized complete block with three replications in College of Agriculture, Shiraz University in 2012, to compare the effects of 6 types of non-living mulch (clear plastic, black plastic, wheat straw, sawdust, coco peat and peat moss) with metribuzin on weed control, total yield and marketable yield of tomato cv "CH". The results showed that there is no significant difference between wheat straw mulch and cocopeat with mtribuzin on tomato yield. In addition, plots treated with black plastic mulch and sawdust respectively had the highest (20.93 kg/m2) and the lowest (3.40 kg/m2) tomato yield. Clear plastic mulch and wheat straw showed 7.66and 62.33 weeds per unit are a which respectively had the highest and the lowest efficiency on weed control. While among all of mulch treatment, only the clear plastic mulch had no significant difference with mtribuzin on weed density per unit area. So, according to the results, clear and black plastic mulches had more positive impacts on weed control and yield of tomato than metribuzin and the other mulches.
