The effect of nitrogen fertilizer (Urea) on greenhouse tomato and field and the effect of planting date of fall season on greenhouse tomatoes grown under the evaporative cooled greenhouse were evaluated. Nitrogen fertilizer (Urea) increased the number of flowers, number of fruit set, and yield of both greenhouse and field of tomato cultivars, as well as number of branches of field cultivation, carmello of greenhouse tomato produced the highest yield and Strain-B of field tomato was the best among field cultivars. Early planting in September for fall season was better in growth, flower number, fruit settig and yield of greenhouse tomato cultivars grown under evaporative cooled greenhouse. The response of tomato cultivars to planting date was variable. F1 Trasque was the only cultivar which did very well in late planting., It seems that the best planting date for all planting of greenhouse tomato is between mid or early August to mid September
