Abstract: Climate change has become one of the most important factors affecting in agricultural production, the impact on our global food supply. We must expand our focus to avoid its effect on the crop’s productivity. Environmental control inside greenhouse can be used to avoid the impact of different environmental changes. This work studies the effectiveness of greenhouse cooling by the solar energy -assisted evaporation concerted with painting its cover by influential coating material on the cucumber productivity and quality. To achieve this goal, the work was divided into two main experiments. The first one was the preliminary experiment; it was carried to choose the strong and effective parameters of treated coating materials which prevent the maximum value of solar radiation. The second one was the field experiment to validate the preliminary experiment integrated with solar-assisted evaporative cooling system for greenhouse cooling. The field experiment was done to assess both of the cucumber yield and quality under treated with control greenhouses. From the preliminary experiment, results showed that painting the cover using the selected material achieved the least transmission coefficient (0.59) and the lowest temperature (31.6 oC). Painting the greenhouse cover alongside evaporative cooling system which consumed 8.32 MJ day-1 attained from solar system (PV) decreased the temperature about 10 degrees. The yield increased by 11 %. The cucumber weight losses with control greenhouse increased by 21.6% compared with the treated greenhouse. This system can be applied to refrigerate most facilities with great efficiency to maximize the productivity and quality.
