2 ) in each group, the each of these was mixed with 2kg organic/m 2 , 2kg/m 2 organic alone and control (without fertilizer) used as a sub plot. Hybrids were assigned to be the main plots. The seedlings were transplanted on one side of 80 cm ridges and 40 cm plant spacing. The organic fertilizer was incorporated in soil before planting, whereas the NPK doses were added as powder weekly after two weeks from transplanting. Fruit quality was accessed as percentage of marketable fruits/m 2 , fruit diameter, total soluble solid "TSS", fruit acidity and ascorbic acid content. The means were compared using Duncan Multiple Range Test (DMRT) at P < = 0.05. The results showed that T 2 from NPK combination with or without organic fertilizer gave significant positive effects on all quality parameters tested in both seasons. The results also showed that there was no significant difference between the two hybrids in response to NPK combination with or without organic. The quality values were decreased with increased fertilizer dose above T 2 showing that excessive NPK fertilization (T 3 with or without organic) for high quality tomato under evaporative cooling system is not recommended.
