Although the production of hazelnuts has been limited in 16 provinces in recent years, the establishment of new hazelnut orchards is prohibited by law when first, second class and slopes in the land of below 6 percent. It is desirable to expand hazelnut production in the provinces that contain these features. The aim of this study is to forecast changes of leading ten provinces in Turkey's hazelnut production in the future seven years. In the study, ARIMA models were used to obtain the forecasts for the future by taking into account the data of TURKSTAT 1991-2018. Considering the criteria such as AIC, BIC, SSE, MSE and MAPE the most appropriate ARIMA model has been determined. According to the 28-year average, the provinces with the highest production were Ordu, Sakarya, Giresun, Samsun,Trabzon, Düzce, Zonguldak, Kocaeli, Artvin and Bartın, which their percentage were 27.82, 16.28, 14.77, 11.52, 8.75, 8.68, 3.69, 1.66, 1.15 and 0.55, respectively. These ten provinces constitute 94.87 percent of Turkey's hazelnut production. According to the average of the years 2019-2025, these provinces will produce annually average 589 thousand tons hazelnuts and will be provide 97.89% of Turkey's hazelnut production. When yield and price are taken into consideration, yield and quality increase is generally provided in these provinces. However, there are needed to be developed hazelnut varieties by the Hazelnut Institute order to prevent yield and price decreases in some provinces. In addition, both yield and quality will be increased with rejuvenated of aging gardens with these varieties.
