Little pieces of plastic can scatter across a field. Many landfills also will not accept plastic, and it is difficult to recycle. The cost of applying plastic mulch can be quite high both in terms of materials and equipment. With drip irrigation, managing plastic mulch is more intense. Wilting plants could mean a plugged drip line, while overly wet areas could mean rodent damage to the lines. Drip line problems are hard to evaluate when covered with mulch. Although that, we suggest popularization of these study to include other crops that more profit for farmers such squash, pepper and tomato, and hope use other many colors of plastic mulch and examination them effect on water use efficacy (WUE), and Potential to double-crop plastic mulch (see Waterer et al., 2008). We advise use organic mulch also such as rice, wheat and barley straws and do not advice use of plastic mulch on potatoes which planted in Autumn season because of high soil temperatures under plastic mulch will destroyed potato nodes (see Wang et al., 2004).
