Undercovered activities in Turkey have been developed due to ecological conditions, and have become widespread in the Aegean Region, especially in the Mediterranean coast, where the climate is favorable. In the province of Aydin in the Aegean Region, 45 farmers engaged in undercover farming determined by the Aydin Provincial Directorate of Agriculture and Forestry were surveyed and mesurement and photographing of structures were studied. In the survey, the structural system used in undercover cultivation and their structural characteristics were determined. Common problems encountered in under covered structures were identified. Information on heating, heat preservation, irrigation, ventilation, cooling and illumination of undercovered structures were obtained. As a result of the research, the structural features and competencies of the undercover production systems in the region were determined and suggestions for the development of these structures were presented. It has been evaluated whether the recent developments and changes of undercover enterprises are reflected in the traditional undergone production in Aydin region and the current situation of undercover structures in recent years has been evaluated.
