Abstract

Painting the plastic cover of the greenhouse is an effective method to achieve a suitable environment for crop growth and to enhance crop productivity and quality in hot and sunny regions. The influence of painting with white plastic as shading material was studied in faculty of Agriculture, Shebin El Koum, Menoufia University, on cucumber crop. Drip irrigation water was applied at four levels which are: 70, 80, 90 and 100% of the potential evapotranspiration (ET_o) in two greenhouses. One was with painted cover and the other was without painting. The results showed that the painted cover greenhouse with white emulsion paint gave the highest yield of 15.5 Mg/fed at the water application rate of 80% of potential evapotranspiration. The highest rate of increasing cucumber length (6.69cm/day) was observed with unpainted plastic cover and occurred after 4 days at 70% of ET_o. The highest value of water use efficiency with painted plastic covers (10.23Kg/m³) was achieved at 80% ET_o, while with unpainted plastic cover (9.42Kg/m³) at 70% of ET_o.
