In this study the effect of zinc fertilization on some nut traits and the nutritional composition of \u2018Tombul\u2019 hazelnut (<jats:italic>Corylus avellana<\/jats:italic> L.) variety cultivated in the Black Sea region of Turkey was investigated and the contribution of this nut to human nutrition determined.
