The current study was conducted at El-Nubaria area, , El- Behera Governorate, Egypt, during autumn 2009 and 2010 seasons in order to investigate the growth and productivity of cucumber (Cucumis sativus L. c.v. Hesham F1 hybrid) under different plastic net cover colours and different plastic mulch colours. Seeds were sown on first of September and seedlings were transplanted in 15th of September 2009 & 2010, respectively. Three plastic net colours were applied, namely, red, blue and white whereas the white was used as a control. In addition two-soil plastic mulch colours (black and transparent) were applied for each house, besides bare soil (without mulching) as control. The best results were obtained under the white plastic net (control), which had the highest total yield as well as light intensity, followed by the red, and finally blue plastic net colour. The highest length of plant, total leaf area and number of leaves as well as air temperature and humidity, soil temperature, were found in the red plastic net colour, followed by control and finally with the blue plastic net cover colour. Results also indicated that the white plastic mulch was recorded the highest values of all measured parameters followed by black and without mulching. Interaction between plastic net colours and plastic mulch showed that, the white net with transparent plastic mulch treatment had the highest plant, yield and soil temperature, but the treatment of transparent plastic mulch under red net colour had the highest number of leaves, leaf area and stem diameter.
