Drought is one of the most important stresses for crops that do not have same effects on growing stages. Recently, drought involved many various agriculture crops such as Date palm tree. This experiment carried out in a randomized complete blocks design with six treatments and five replications, in order to determine the critical and sensitive stages of date palm growth to water stress. The treatments were: 1) irrigation in whole of year 2) irrigation in whole of year without rest stage 3) irrigation in whole of year without pollination stage 4) irrigation in whole of year without fruit set to Kimri stage 5) irrigation in whole of year without Khalal stage 6) irrigation in whole of year without Rotab and Tamar stage. In harvest time, sample from 30 trees analyzed to determine different quality and quantity characteristics of fruit. Vegetative growth indices were measured every year. The four years results showed that the effects of treatments were significant in 5 percent level on leave and leaflet width, fruit diameter and shape and they were significant in 1 percent level on tree perimeter, leaflet number and length. Yield and other indices have not significant different. In conclusion, Khalal and pollination stages have sensitive least and most to water stress respectively. conditions
