| Abstract | ||
| This experiment was conducted with the aim of investigating the role of nutritional elements on the vegetative and bearing traits of pistachio (Pistacia vera L.) of the Badami-sefid cultivar. For its implementation, 4 fertilizer combinations were used in 5 treatments, including 1-fruit set combination + complete nutrient elements fertilizer + calcium and potassium fertilizer, 2- the first treatment minus potassium fertilizer, 3- the first treatment minus potassium and calcium fertilizer, 4- fruit set alone and 5- control (including boric acid, urea and zinc sulfate at a ratio of 5 per thousand each( in 5 replication (each replication including one tree), in a randomized complete blocks design (RCBD) on 10-year-old Badami-sefid pistachio trees in the orchard of Khorasan Razavi Pistachio Research Station (2021-2023) in Faizabad. The most important traits include the length and diameter of the terminal shoot, the number of flower buds and the percentage of flower bud's abscission in the terminal shoot, the number of fruits in the cluster, the percentage of blank, fruit weight, and yield were measured. The results showed that the shoot treatments were significant on the traits of fruit formation percentage, hull percentage, pistachio ounce, splitting percentage, flower buds percentage, average terminal shoot diameter, and fruit fresh weight (P≤0.01). The highest splitting percentage was obtained at 95% in treatment No. 2 and in the first year and the lowest at 83.2% in the control treatment of the second year. Also, the percentage of blank in treatment No. 2 was the minimum at 25.90. The highest dry weight of the fruit (33 ounces) was obtained in treatment No. 1 with 9.5 kg/tree fresh fruit and control treatment with 8.05 kg/tree had the highest and lowest yield, respectively. In total, treatment No. 1 increased the yield about 15% more than the control treatment. | ||
