Abstract :The study aims to determine the changes in annual tea yield in Turkey between 1975 and 2019 and analyse the yield relationship with temperature and precipitation conditions. Within the scope of the study, statistical relationships between monthly temperature and precipitation data and annual tea yield were examined. In addition, the annual changes and trends in the yearly tea yield were revealed. As a result of the study, a statistically significant positive relationship was determined between annual average, maximum and minimum temperatures and annual tea yield. On the other hand, the relationship between total yearly precipitation and annual tea yield was insignificant. Relationships between temperature and yield are more substantial in summer. A statistically significant increasing trend was defined in tea yield during the 1975-2019 period in the research area. There was a considerable increase in annual average temperatures in the same period but an insignificant increase in precipitation. In the light of these, an increase in tea yield due to temperature rises can be expected in the region by looking at climate change scenarios.
