Three treatments were layout in completely randomize block design with three replicates . The treatments were conventional furrow irrigation ( control ), fixed Alternate furrow irrigation which mean to irrigated one furrow from two adjacent and exchange alternate furrow irrigation which mean exchange the closing one of the adjacent furrow for each irrigation . The results indicate that there was no different between furrow irrigation treatments in number of day of flowering , stem diameter , head diameter leaf area and leaf area index .Exchange alternate furrow irrigation was not differ from the control in seed weight and seed yield . The surprising result that the water use efficiency was exceeded by 37 % than control with reduction 38 % in water use .
