Abstract - We studied the effect of boric acid, Zn-sulfate and Zn-chelate on shell split and development of fruit rot diseases of the pistachio cultivar Eginis. The results showed that boric acid applied to soil and leaves together gave the highest percentage of shell split. Boric acid applied solely to the soil also increased significantly the percentage of shell split. In contrast, Zn-sulfate and Zn-chelate did not affect shell splitting, regardless of treatment No rotten fruit was found in any of the treatments, including the control.


Key words: boron / Eginis / shell split / pistachio / zinc
