The Effect of Boron and Zinc Containing Foliar Fertilizer Applications on Leaf Mineral Content of '0900 Ziraat' Cherry (Prunus avium L.) Cultivar

Abstract

This study was carried out in two different cherry orchards in Yeşilli (Mardin) district in 2018 in order to determine the effects of foliar fertilizers containing boron and zinc on the leaf nutrient content of '0900 Ziraat' cherry cultivar grafted on Prunus mahaleb L. rootstock. It was found that both cherry orchard soils in which research was conducted had a slightly alkaline character, the level of organic matter was quite low and the content of lime was high, while phosphorus, zinc and boron elements were deficient. In the study following mixtures and concentrations in 100 liter of water: control (no added nutrients), Maxifruit at 150 cc (1st application), Fertileader® Oris at 150 cc (2nd application) and Fertileader® Oris at 100 cc + Fertilader® Alpha at 50 cc (3rd application) were applied by foliar spraying. Two foliar applications were performed at two different timings between 15-30 days and 30-45 days after full flowering. In the study N, P, K, Ca, Mg, Fe, Cu, Zn, Mn and B content of leaves of '0900 Ziraat' cherry were analyzed and the effect of foliar fertilizers on macro and micro element content of '0900 Ziraat' cherry leaves were found to be significant. The highest N (2.18%), the highest P (0.34%) and the highest K content (2.31%) were obtained from the 1st application, control application and the 2nd application, respectively. While the highest Ca (1.90%), Mg (0.53%), Fe (129.84 ppm), Cu (14.93 ppm), Zn (24.52 ppm), Mn (42.03 ppm) and B (40.61 ppm) contents were obtained from the foliar fertilizers used in the 3rd application. According to the results it can be said that providing fruits resistance to transportation and meeting export-market standards in terms of fruit size by applying the appropriate fertilization program based on the results of leaf and soil analysis will give rise to the demand for income-generating cherry orchard for the local farmers. © 2022 Elsevier B.V., All rights reserved.
