Abstract
The use of polyethylene mulch has increased dramatically in the last 10 years, in Iran. Because they have many benefits: increase in soil temperature especially in early spring, reduced weed problem, moisture conservation and higher crop yields. A field experiment was conducted on tomato (Lycopersicon esculentum L.) at during growing season (April-July) in 2010, in a randomized complete block design with three replicates. Treatments consisted five colored polyethylene mulch (clear, black, blue, red and silver on black) with bare soil (weed free) and un-weeded as controls. Results showed that soil temperature under the various colored mulches was 3 to 6 ˚C warmer compared to bare soil. The highest soil temperature was recorded under blue plastic. The plants grown on silver/black mulch produced Maximum marketable yield and fruit weight. The silver/black and black plastic mulches resulted in a 95-98% reduction in weed biomass. In an attempt to reducing chemical input for weed control and increase to yield of tomato black and silver/black plastic mulch may be a good alternative for conventional clear plastic mulches.
