Effect of Soil Application and Foliar Boron (Etidot-67) On Hazelnut Yield and Kernel Ratio

This is not a clear effect of boron fertilizers on fruit yield and hazelnut quality. However, soil deficiency common nutrient problem for growth. In this study, the fertilizations foliar was investigated quality hazelnuts (Corylus avellana L.) in two provinces Turkey between 2013 2014. The experimental trials were carried out application (0.0, 3.0 6.0 g per Ocak) spraying (0 300 mg B L-1). Results show that compared with control, increased Due to two-year average, highest Samsun-Çarşamba obtained from dose S1. A 36.70% increase achieved by applying (3g Ocak-1) comparison control application. It 20 % Ordu-Ulubey district. kernel ratio F1S2 applications districts. Increases observed at (10%) Ordu-ulubey (7%). showed there also positive association leaf concentration no significant differences As result increasing yield, are an effective method supplying sufficient flowers. addition, more appropriate than
