Yamula Eggplant

Yamula Eggplant is a unique variety of eggplant cultivated in the village of Yemliha and its surrounding areas, located in the Kocasinan district of Kayseri. It has developed distinctive taste and aroma characteristics through adaptation to the region’s climatic and soil conditions. On 27 November 2007, it was officially registered with a geographical indication and placed under protected status.

The area around Yemliha village and Yamula Dam stands out as the sole region where this eggplant is grown, thanks to its unique microclimate, fertile soil structure, and long-standing agricultural traditions. The production and promotion of Yamula eggplant have become an integral part of the region’s cultural life since festivals began to be held annually starting in 1997.

Distinctive Features of the Product

• The light purple peel with white streaks,
• The whitish flesh and seedless or nearly seedless structure,
• The absence of bitterness and fibrous texture,
• Early ripening during the harvest period.

The land where it is grown differs in agricultural quality due to the mineral richness provided by the Kızılırmak River valley.

In spring, a base fertilizer (DAP) is applied, followed by nitrogen-based fertilizers throughout the summer. Irrigation intensifies at the beginning of July, with row spacing maintained at 60 cm.

Harvesting begins in the last week of July and continues until the first week of October. One hectare can yield 4–6 tons per season.
