The probability of cultivation of citrus crops on the territory of the Black Sea coast of the Caucasus

Abstract

According to the result of analysis of 30-year series of agro-climatic data, it shown that south part (Sochi region) of the Black Sea coast of the Caucasus is the most suitable area on the coast for citrus fruits cultivation. Central part of coast has almost optimal agroclimatic indicators and corresponds to all demands and limiting factors of citrus, except for rear short frosts, but without extra loss in crop yields. Northwest part of the Black Sea coast (Anapa region) correspond to the citrus fruits cultivation in terms of heat supply, but inferior in terms of water supply, soils, and criterion of frost susceptibility of the territory. As a result, the cultivation of citrus crops in this area is quite risky, since involves large losses in harvest without appropriate adaptive agrotechnical activities.
