The Trakya Agricultural Research Institute in Edirne, Turkey, has been conducting research on improving agricultural production since 1923. The institute has developed many varieties of paddy, sunflower, wheat, and barley, including the most cultivated rice variety in Turkey, 'Osmancık'. The institute's director, Assoc. Dr. Adnan Tülek, stated that their paddy varieties make up half of the certified seed production in the country. The institute's cultivars have also attracted attention abroad, with registrations in Bulgaria, North Macedonia, and Ukraine. The institute has also developed paddy cultivation methods using drip irrigation systems, which are important for paddy farming in water-limited areas.
