© 2021, Springer-Verlag GmbH Deutschland, ein Teil von Springer Nature.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.
