“…In our study, the cultivar 'Uzun' had a higher yield than 'Siirt' , which contrasts with the findings of several other studies that have shown that 'Siirt' has a higher yield than 'Uzun' (Arpacı et al, 1995;Açar et al, 2005Açar et al, , 2011. The yield of 'Uzun' was correlated with the concentration of the Tarımbor application (r = 0.9257), but no such correlation was observed for 'Siirt' (r = 0.0490).…”

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 18.5% 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%, 0.1%, 0.2%, and 0.3% 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 0.3% 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 concentrations of B were applied. Thus, Tarımbor could be used effectively as a foliar spray to enhance the B levels in the leaves of pistachio trees grown under nonirrigated conditions.

“…In pistachio, final fruit set varied between 9.40% and 16.50% of flowers Kuru & Ayfer 1990) and depended on pollination, fertilisation, nutrition, irrigation, and pruning (Goldhamer et al 1988;Arpaci et al 1995;Tekin et al 1995). According to Crane & Iwakiri (1981), embryo abortion in pistachio has been variously attributed to lack of pollination, poor nutrition, rainfall during anthesis, and water deficit during seed development.…”

This study was carried out at the pistachio (Pistacia vera) orchards of Ceylanpınar State Farm, Turkey. The cultivar 'Siirt' and Male 13 were used in the experiments. The aim of the study was to investigate the effect of pistil receptivity, pollen mixtures, and pollen application distances on fruit set using artificial pollination in pistachios. To determine the receptivity of female flowers, anthesis was accepted as day 0, and then one application was carried out on 0, 2, and 4 days after anthesis; and repeated applications were done on 0+2, 0+4, 2+4, and 0+2+4 days, separately. Pollen and wheat flour was mixed to obtain 1%, 5%, 10%, 50%, and 100% pollen mixture, and these pollen mixtures were sprayed from 25, 50, and 100 cm distances from the inflorescence clusters with a small hand sprayer. Thus, fruit set was determined for the applications. Different pollen mixtures were applied to a microscope slide, covered with Vaseline, from three different application distances to determine the number of pollen grains per unit area by artificial pollination. The number of pollen grains per unit area was counted under a light microscope and calculated per 1 mm 2 . Finally, adequate pollen numbers to pollinate a flower were determined. The results indicate that for optimum fruit production of pistachio, 5% and 50% pollen mixtures should be sprayed at a distance of 100 cm at 0 and 4 days after anthesis. The adequate number of pollen grains to pollinate a flower was calculated as 14 or 15 pollen grains per flower in pistachio. Increased number of pollen per stigma area would cause excessive flower abscission after a certain point, and this could be the cause of low fruit set in pistachios.
