Two field experiments were conducted during the two consecutive growing seasons of 2013/2014 and 2014/2015 at Sakha Agriculture Research Station Farm, Kafr EL-sheikh governorate. The aim of study was to evaluate the effect of three irrigation discharge rates (2.5, 3.5 and 4 L.sec^-1 m^-1) and three cut-off irrigations (100%, 90% and 85% from border length), which were randomly arranged under each irrigation discharge on wheat yield and its components, some water relations, irrigation efficiencies and the contribution of ground water table. The results revealed that the combination of irrigation discharge 4 L sec^-1 m^-1   and cut-off irrigation at 85% of border length achieved the lowest values of seasonal applied water and water consumptive use and the highest values of following parameters ; crop water use efficiency (CWUE), Irrigation water use efficiency (IWUE), water consumptive use efficiency (Ecu, %), water application efficiency (EI, %), Grain and straw yields, NP– uptake and crude protein and ground water contribution (Gwc, %). Moreover, it increased the amount and percentage of water saving 242.34 m3 fed-1 (about 9.60%), total income, net income, and net income per water unit for both wheat grain and biological yields. Also, the economic efficiency, during both seasons. On the other hand, the highest values of water distribution efficiency (Ewd, %) have resulted from the combination of irrigation discharge rates (4 or 3.5 L sec^-1 m^-1) and cut-off irrigation at 100% of border length. It could be concluded that the combination of irrigation discharge 4 L sec^-1 m^-1   and cut-off irrigation at 85% of border length was the most profitable for irrigated wheat crop, as well as, the benefit of contributing ground water table in saving some of water requirements for the crop, ground water table contribution of great importance as an additional source of irrigation water, especially under the prevailing conditions of water shortage in Egypt.
