The present study was conducted to investigate the some characteristics and of water use efficacy of Ziziphus spina christi and Prosopis cineraria under different irrigation levels in the 2018-2019 crop year. Different irrigation levels consisted of 75, 50 and 25 percent irrigation and irrigation at field capacity (control), which was applied in a completely randomized design with four replications. The results showed that the mean water consumption or in other words evapotranspiration per year is equal to 35.41, 49.86, 62.43 and 79.34 liters for treatments of 75, 50, 25% of field capacity and control in the plant. Was aside. Also, the highest amount of evapotranspiration in July and in the studied treatments were equal to 5.58, 7.71, 9.81 and 12.38 liters, respectively.. The average amount of water consumption in Prosopis cineraria plant was equal to 23.03, 32.59, 41.94 and 53.92 liters for treatments of 75, 50, 25% of field capacity and control. In the case of Prosopis cineraria, the maximum evapotranspiration rate was 7.55 liters for the control treatment and 6.31, 4.96 and 3.59 liters for the 25, 50 and 75% irrigation treatments, respectively.
