This study was carried out in the Agro-industry Complex of Gohar Kouh, Khash in Iranshahr. A split-plot experiment based on RCBD was employed with three irrigation intervals including 1: 30 day interval 2: 40 days of irrigation interval 3: 60 day irrigation interval along with three levels of nitrogen application including 1: no nitrogen fertilizer 2: 750 grams of nitrogen fertilizer per tree 3: 1500 grams of nitrogen fertilizer per tree as a sub plots. The results showed the highest yield was 4349 grams per tree that belonged to trees irrigated in 30 day intervals, and with the highest nitrogen application level. The lowest yield was obtained from I40N0, I40N750, I60N0 treatments. Each of the irrigation interval treatments with N0 level showed the lowest vegetative growth. Vegetative growth was improved by increase in nitrogen application level in most of the treatments. The most vegetative growth rate was obtained from the treatments of I30N1500 and I40N750 namely 13 and 12.4 centimeters of growth respectively while the lowest vegetative growth was obtained from treatments of I60N0 and I40N0 namely an average of 7.2 centimeters of vegetative growth. Results indicated that, the most nitrogen concentration resulted in leaf growth of 1.9 percent (I60N1500 treatment) while the lowest nitrogen concentration (I30N0 treatment) ended up with a leaf growth of 1.4 percent.
