Black plastic mulch can give a harvest earlier by some 2438 7-14 days, while clear plastic may advance the harvest date by 21 days. Soil water loss is reduced under plastic mulch. As a result, more uniform soil moisture is maintained and irrigation frequency can be reduced. The growth of plants on mulch can be twice that of plants in un-mulched soil. Because larger plants will require more water, mulching is not a substitute for irrigation.
