Distribution of agricultural crops in the dry subtropics of eastern Georgia.
2021
Based on the analysis and statistical processing of data of multi-year (in 1948-2017) meteorological observations in the eastern dry subtropical conditions of Georgia (Kakheti, Mtskheta-Mtianeti, Kvemo Kartli, Shida Kartli) a trend of increase/decrease the duration of vegetation periods, sums of active temperatures (>10°C), atmospheric precipitations (mm) and hydrothermal coefficients (HTC) have been identified. In order to present these values clearly, the data of 70-year-long observations mentioned above were divided into two 35-year-long periods. The I period covers the years of 1948-1982, and the II period covers the years of 1983-2017. Taking into account the increase in the sums of active temperatures (>10°C), a dry subtropical agroclimatic zone has been allocated for the distribution of prospective crops. Tab. 3, Fig. 1, Ref. 5.
