Distribution of red beet in high mountain agroclimatic conditions of Georgia

Distribution zones of red beet in high mountain agroclimatic conditions of Georgia are discussed. On the basis of agrometeorological indices, two zones of distribution of red beet are distinguished. The first zone extends from 1400 meters to 2000 meters above sea level, where the sum of active temperatures (≥10°C) make 2000-1200°C. The second zone extends from 2000 meters to 2400 meters above sea level, where the sum of active temperatures (≥10°C) make 1200-700°C. The dates of the phenological phases of red beet and the agrometeorological indices between the phases are given. For highland conditions, a close correlation (R=0.96) between yield and agrometeorological factors (atmospheric precipitations, soil moisture and temperature) has been established. According to the mentioned attitude, a red beet yield prediction equation has been drawn up.
