Abstract

The effects of six colored polyethylene mulches (white, black, red, blue, silver and transparent) and uncovered soil on the quantitative and qualitative characteristics of bell pepper plants and fruits and the rate of weed growth inhibition were investigated in a field experiment for two consecutive years. Application of white polyethylene mulch resulted in the highest rate of early yield and total yield of pepper fruit. Premature yield occurred in silver, red, black, blue, uncovered soils, and clear plastics, respectively. Plant growth factors, number of fruits and the rate of weed growth inhibition were significantly affected by different colors of mulch, but fruit quality factors were not affected. Among colored polyethylene mulches, white mulch is recommended to increase early yield and total yield of bell pepper by increasing the number of fruits.
