Lettuce is produced in Bilecik's Söğüt and İnhisar districts and the Sakarya Basin, with most of it being sent to surrounding metropolitan cities, especially Istanbul. The Provincial Directorate of Agriculture and Forestry supports lettuce production in the area, providing greenhouse cover renewals and distributing 5 million lettuce seedlings to farmers. The majority of the villagers in the region earn their living from greenhouse farming, with the lettuce season starting and the majority of the produce being sent to Istanbul.
