In terms of quality, the application of Tarımbor appeared to have a greater effect on ‘Uzun’ than on ‘Siirt’. No vegetative symptoms of B toxicity were observed in either cultivar when high concentrations of B were applied. | Turkish Journal of Agriculture and Forestry Research Article Turk J Agric For (2016) 40: 664-670 © TÜBİTAK doi: Boron affects the yield and quality of nonirrigated pistachio (Pistacia vera L.) trees 1 2, 3 3 İzzet AÇAR , İlhan DORAN * , Nevzat ASLAN , Nilgün DOĞRUER KALKANCI Department of Horticulture, Faculty of Agriculture, University of Harran, Osmanbey Campus, Haliliye, Şanlıurfa, Turkey 2 Department of Horticulture, Faculty of Agriculture and Natural Science, University of Bilecik Şeyh Edebali, Gülümbe, Bilecik, Turkey 3 Pistachio Research Institute, Şahinbey, Gaziantep, Turkey 1 Received: Accepted/Published Online: Final Version: Abstract: In Turkey, more than 95% of the pistachio (Pistacia vera L.) orchards are not irrigated. Therefore, a 4-year field trial was conducted to determine the effect of Tarımbor fertiliser (containing boron [B]) on the yield, quality, and B content of two pistachio cultivars (‘Uzun’ and ‘Siirt’) planted under nonirrigated conditions. Tarımbor was applied to the pistachio trees as a soil application (0, 200, 400, and 600 g/tree) and a foliar spray (0%, , , and w/v, using a tractor-mounted sprayer at the ‘early bud break’ stage and the ‘fully leafed out’ stage). Both the soil and foliar applications of Tarımbor had a significant effect on the pistachio yield, quality, and B content compared with the control. However, the foliar application resulted in greater improvements in the B content of leaves in both cultivars and the split nut ratio and kernel ratio in ‘Uzun’. The greatest increases in yield were observed for the foliar application for ‘Uzun’ (30%) and the 200 g/tree soil application for ‘Siirt’ (59%). In terms of quality, the application of Tarımbor appeared to have a greater effect on ‘Uzun’ than on ‘Siirt’. No vegetative symptoms of B toxicity were observed in either cultivar when high .
