Abstract
Incompatible cultivars is one of the reasons low yield in the country's pistachio orchards. The purpose of this experiment was the top working of three commercial pistachio cultivars Akbari, Ahmad Aghaei and Badami-Sefid in three regions of Bajestan, Gonabad and Mashhad, which was carried out in a completely randomized design with three replications and 5 trees in each replication. The grafting percentage, annual growth length and diameter, number of lateral branches on two-year-old branches, tree height and width, number of flower buds on terminal branches and lateral branches, number of cluster and yield were recorded for each cultivar (2021-2024). The results of the first year showed that the grafting percentage in the two cultivars Akbari and Badami-Sefid was about 90%, higher than the Ahmad-Aghaei cultivar with about 76% (p<0.01). In the second year, the growth of the current year's branch in the Badami-Sefid cultivars in the Mashhad region was 78.60 cm higher than the Ahmad-Aghaei cultivars in the Mashhad region with 54.60 cm. In the third year, flower buds were observed on grafted trees. The greatest number of flower buds on the terminal branch was 5.72 in the Akbari cultivars in Gonabad region and the lowest was 0.44 in the Badami Sefid cultivars in Gonabad region. The results of the fourth year showed that the highest fresh yield was obtained in the Badami-Sefid cultivars in the Mashhad region with 3464 grams, and the lowest was obtained in the Badami-Sefid cultivars in the Gonabad region with 99 grams. Overall, the highest vegetative growth and yield for the Mashhad region was the Badami Sefid cultivars, and for the Bajestan and Gonabad regions, the Ahmad Aghaei cultivars.
