Pistachio (Pistacia vera L.) is a plant species that has gradually started to be included in the plant patternin the Mediterranean and Southeastern Anatolia regions in recent years. In these regions where boron(B) deficiency may be common in terms of soil and environmental factors, it is very important todetermine the B nutritional level of the plants, especially the Pistachio which is sensitive to B deficiency.Based on this point, within the scope of this research, the shoot B concentration of the pistachio plant inincreasing doses of B (0%; 0.2%; 0.4%; 0.6% and 0.8%) application from the leaf in two differentperiods when the bream explosion was 20% and the fruit was in the lentil size period and its effects onnutrients have been investigated. For this purpose, trial random blocks in the production areas wheretwo pistachio varieties (Uzun and Kırmızı) were grown under garden conditions were carried outaccording to the trial plan. As a result of the research, it was determined that plant varieties and appliedfertilizer doses had a significant effect on B concentration. Under all B applications according to plantvarieties, it was determined that the B concentration was higher in the Kırmızı (21%) variety than in theUzun variety (8.3%), the average B concentration was 200.3 mg kg-1in the Kırmızı variety and 176.3mg kg-1 in the Uzun variety. It was determined that the B concentration in the shoot of the plant increasedwith increasing doses of B application, and these increases (36.8%) were statistically significant at only0.6% B dose application compared to the control. No statistically significant effect of boron applicationon the analyzed macro (N, K) and micro (Zn, Fe, Mn) element concentrations was found.
