The objectives of this study were to determine the effect of soil and leaf nutrients on pistachio yield in the Rafsanjan area, central Iran. Six pistachio orchards which were similar on management, pistachio cultivar, water quality and irrigation period but consisted of different parts regarding growth and yield were selected and divided into two desired and undesired parts. In each part, three replicates and in each replicate three trees were selected. Mean of pistachio yield was determined for each replicate. Leave samples of trees were collected in three different times (nut filling, common sampling time in the region and after harvest) and their macro and micro nutrients were measured. Also, soil sampling was done in 0-40 and 40-80 cm depths to determine the above mentioned nutrients. Results showed that sodium and boron concentration of in the soil and leaves are two dominant restricted factors to decrease pistachio yield in the region. Proper management is recommended to reduce soil salinity
