This study was conducted in the Jordanian Bashair project, River Nile State, during two seasons (2007 and 2008) to evaluate the performance of irrigation systems applying different amounts of irrigation water. The treatments were surface irrigation method (basin irrigation system) and localized irrigation system with two types of distributors: locally made bubblers and imported bubblers. The irrigation water amounts were given as percentages (50%, 75% and 100%) of date palm watering requirement (ETc). ETc was obtained from the means of the previous thirty years, using CROPWAT4 WINDOWS. The performance of the irrigation system was evaluated with reference to the application and storage efficiencies and distribution uniformity. The experiment was organized in a split plot design with three replicates. The irrigation systems showed negative effect on distribution uniformity and positive effect on application and storage efficiencies. The locally made and imported bubblers revealed highly significant (P 0.01) differences with application and storage efficiencies, while there was no significant difference between them. The 50% ETc recorded high significant values of application efficiency, but less values of storage efficiency and distribution uniformity. Interaction of the irrigation systems and amounts of water showed positive effect, whereas locally made bubblers showed higher values of application and storage efficiencies with 50% and 100% ETc, respectively. On the other hand, the basin irrigation system gave highest values of distribution uniformity with 75% and 100% ETc. Hence, it was concluded that using bubbler irrigation system would give high irrigation efficiency, thus saving water for other agricultural activities
