The document discusses Turkey's ranking among the top ten hazelnut producing countries in the world. Turkey is consistently the largest producer of hazelnuts, accounting for over three-quarters of global production annually. The majority of Turkish hazelnut production occurs in the northern coastal provinces of Ordu, Samsun, and Sakarya. Turkey has achieved a high level of self-sufficiency in hazelnut production and is the dominant exporter, shipping over 80% of its hazelnut crop to European markets each year.
