In order to determine the water requirement of apricot trees and the best Irrigation systems, an experiment was carried out using a randomized complete block design in four replications for 6 years. Irrigation water and irrigation systems were used in the following treatments: I1= water application based on 55% evaporation from class A pan; I2= water application at 75% evaporation from class A pan; I3= water application at 110% evaporation from class A pan. D1= Microjet Irrigation system; D2= Drip Irrigation system; and D3= Bobler Irrigation system. For establishment of apricot seedlings all young trees were irrigated uniformly for 3 years. Irrigation systems installed for the fourth year and tested. During the fifth and sixth years all of the trees were irrigated according to the experimental design. The amount of irrigation treatments (I1, I2, I3) were 4950, 6360, 8970 m3/ha in 1380 (2001) and 4650, 6240, and 9020 m3/ha, respectively, in 1381 (2002). Statistical analysis showed that the irrigation treatments highly significantly affected the fruit yield and water use efficiency (WUE) (p<0.01). According to the experimental analysis, the best treatment was I2D3 (application of water based on 75% evaporation from class A pan in Babler irrigation system). In this experiment maximum fruit yield was gained by the 75% accumulative evaporation from class A pan in Bobler irrigation system with 6295 m3/ha water applied.
