Turkey is the leading producer of hazelnuts of global production. Hazelnuts are generally used in the food industry (e.g. by confectioneries, bakeries, ice-cream manufacturers; in dairy, candy, and chocolate products). They are also a part of a wide range of food including cereals, bread, yogurt, soups, and salads. This study was conducted in the Central Black Sea Region of Northern Turkey, which is the largest hazelnut cultivation area in Turkey. The study aims to investigate the effects of different foliar fertilizers on hazelnut yield and nut properties in terms of human nutrition and health. We tried to determine the effects of different characteristics of foliar fertilizers such as Suryamin BZn (B = 9% B, 4% Zn EDTA chelate), Suryamin 1 of chelate (S = 10:7:6+Micro nutrients; 10% N, 7% P, 6% K, 0.04% B, 0.2% Cu, 0.002% Co, 0.6% Fe, 0.07% Mn, 0.4% Zn, 0.002% Mo) and Suryamin Micro (M = 3% Fe, 3% Mn, 3% Zn, 0.5% Cu, 0.7% B) on cv. Tombul hazelnut yield and certain nut properties. During the years, B and Zn were applied as 300 mg kg⁻¹. All other nutrients were applied as 50 mg kg⁻¹. The highest yield and the average results for certain nut properties such as number of nuts in cluster, nut size, kernel weight, and clove/shoot rates were obtained with the B (Suryamin BZn) applications. The highest rates of kernel and shoot length were obtained with the S (Suryamin 1 of chelate) applications. The highest amounts of healthy and the lowest amounts faulty kernel were obtained from M (Suryamin Micro) fertilizer applications.

土耳其是全球榛子的主要生产国。榛子通常用于食品工业（例如，糖果店，面包店，冰淇淋制造商；乳制品，糖果和巧克力产品中）。它们还是多种食物的一部分，包括谷物，面包，酸奶，汤和沙拉。这项研究是在土耳其北部的黑海中部地区进行的，该地区是土耳其最大的榛子种植区。该研究旨在从人类营养和健康的角度研究不同叶面肥对榛子产量和坚果特性的影响。我们试图确定叶面肥的不同特性的影响，例如苏里亚敏BZn（B = 9％B，EDTA锌4％锌螯合物），苏里亚敏1螯合物（S = 10：7：6+微量营养素； 10％N， 7％P，6％K，0.04％B，0.2％Cu，0.002％Co，0.6％Fe，0.07％Mn，cv上为0.4％Zn，0.002％Mo）和Suryamin Micro（M = 3％Fe，3％Mn，3％Zn，0.5％Cu，0.7％B）。Tombul榛子产量和某些坚果特性。这些年来，硼和锌的施用量为300 mg kg^-1。所有其他营养素的施用量为50 mg kg ^-1。使用B（Suryamin BZn）应用可获得某些坚果特性（例如，簇中坚果的数量，坚果大小，仁重量和丁香/发芽率）的最高产量和平均结果。使用S（螯合剂的Suryamin 1）施用可获得最高的籽粒率和芽长。从M（Suryamin Micro）施肥中可获得最高数量的健康谷物和最低数量的有缺陷的谷粒。
