For statistical studies, three replications in each section Iranian Pistachio and three trees in each replication were selected. Then, from two depths of zero to 40 and 40 to 80 cm in the shade of trees, soil sampling was done to determine some physical and chemical properties. Yield, fruit smiling percentage, trunk circumference, canopy length and tree height were also measured.

Also, in the favorable and unfavorable part of each garden, a profile was dug and described and their classification up to the family level was determined. The results showed that high salinity and clay have a very significant negative effect on yield. The percentage of clay with trunk diameter, canopy length and height of trees and pistachio smile also showed a negative and significant correlation.

Therefore, salinity and soil texture maps are recommended for better management of pistachios in the region. Based on the results of the profile description, the stability of the soils in the dry state in the unfavorable part was more difficult than the desirable part of the garden. The results of soil classification indicate that the soil family can not always show the difference between soils and their effect on pistachio yield.
