ABSTRACT.
During 1997 and 1998 the effect of complementary water supply at different growing stages on production and storage ability was studied. Granex 33 cultivar was transplanted in beds 1.5 m appart with four rows (280000 plants/ha). Small rain out shelters were used, (2x3 m), to cover each plot in different periods . Treatments were: 1. covered ali the growing season and non irrigation in 1997 and non irrigation without cover in 1998; 2. covered from, bulbing to harvest; 3. covered up to bulbing and 4. rainfall plus irrigation. 
Treatment 2, 3 and 4 was similar in 1997 and 1998. When the tensiometers reached -0.25 bar at 20 cm depth. Treatments were arranged in a randomized block design with four replications. Irrigation was applied with drippers at 0.50 m appart anda flow rate of 1.75 l/h. Tensiometers and steel rods were installed at 20 cm depth in each plot to measure soil water content. TDR measurements were collected twice a week. Significant difference in total and marketable yield were obtained both years. Total yield was 51 ton/ha in 1997 and 66.7 ton/ha in 1998, respectively. There were not significant differences in total and marketable yield between treatment 2 and 3 in 1997 and 1998. Non irrigation and treatment 2 showed better storage ability as compared with treatment 3 and 4 in 1997.
