Abstract: Hazelnut plantations, which are a major source of income for the villagers in the eastern black sea region are not able to provide sufficient income to the villagers due to price fluctuations and sudden falls witnessed in recent years. Alternative investments in place of hazelnut cultivation are being investigated in order to prevent migration to urban areas and to increase the welfare of the rural population in the region. Black alder plantation investments have been assessed as one of the most essential alternative investment tools within the framework of the study. Assessment was carried out by comparing expected possible net present values (NPV). Although value increase occurs 12-18 years later, more income can be obtained through black alder than hazelnut plantation. In hazelnut plantations, the best NPV emerged in the lower zone. NPV was positive in the moderate zone but values were close to zero. In upper zone, positive NPV couldn?t emerge. As a result, it was understood that black alder plantation investment is an effective alternative for hazelnut plantations.?

Key words: Hazelnut, Black alder plantation, Net present value
