Irrigation is an increasingly important practice for sustainable agriculture in the Midlist region, as well as in other semi-arid environments of southern Iran. Evapotranspiration (ET) of corn hybrids were measured and compared in 2003 and 2004 under lysimeters at Iranshahr Research Station in the Blochestan of Iran, and studied differences in growth, yield and water use efficiency (WUE). In both years, corn was planted in July and harvested in October in two different fields of 1000m2 each, containing drainage lysimeters to directly measure ET. Irrigation differentiation was made upon crop evapotranspiration measured on the lysimeters, water was then applied at 100 and 60% of ET. Full irrigation treatment (I-100) was managed for high productivity, whereas deficit irrigation treatment (I-60) was maintained at 60% of field capacity. Water stress was applied continuously during the growing cycle. The analysis revealed that SC 704 hybrid is suitable variety for southern of Iran, because WUE of this hybrid %4.4 higher than SC604, While water using of this variety is %2.03 more than SC604. Meanwhile yield and yield components (1000 w, number of row per ear) and plant height are %6.73, %8.39, %11.11 and %5.11 higher than SC604 respectively. On the other hand cob percentage of SC604 as a negative parameters is %10 more than SC 704. In the meantime seed depth of SC604 is other recorded parameter which %5.88 more than SC 704.
