Farm, during 2003 and 2004 seasons. The study aimed to evaluate the irrigation time of 1 hr and 2 hrs. or treatments A and B respectively, under different irrigation intervals of 4, 6 and 8 days (subscripts 1, 2 and 3), respectively. Results showed that the maximum grain yield was obtained from B1 treatment, average value was 3650 kg/fed. (9052 kg/ha). Water requirement for maize was 2870 m3/fed. or 68.3 cm resulted from B1 .i.e. irrigation with 2 hrs. every 4 days under drip irrigation system. In general, the main results indicated that: 1. Grain yield was higher under 2 hrs. irrigation (Treat. B) as compared with 1 hr. irrigation (Treat. A). The average yields, resulted from the different applied water in the two seasons were, 3273 and 2715 kg/fed. for B and A treatments, respectively. 2. Ear length decreased with increasing irrigation intervals under both levels of irrigation. 3. Ear diameter was higher with B1 as compared with the other amount of water regime. 4. The highest value of water use efficiency (W.Us.E.), was occurred with A3 and the lowest was obtained under B1.
