0.01) which can prove different inherent qualitative and quantitative characteristics in date palm cultivars. Zahidi cultivar proved to have higher water use efficiency in water stress conditions during drought periods. Irrigation treatments affected only the yield responses. Although, 65 percent of irrigation water showed to have higher production abut it was classified in the same statistical class with 50 percent of irrigation water. This means that in the situation of water shortage, 50 percent of irrigation water would be the choice. Also, mean water usage during three years of the experiment were 5497, 7758 and 9822 m3 ha-1 per year in the irrigation treatments with 0.544, 0.481 and 0.409 kg m-3 water use efficiency respectively. The sequence of water stress toleration in three date palms was Zahidi > Shahabi > Kabkab.]]>
