Abstract
The purpose. To determine influence of weather-climatic conditions upon phenological phases of development of overground part of stevia. Methods. Field and statistical, data of meteorological stations in Kiev, Vinnitsa and Ternopol for 2008 — 2016. Results. It is proved that weather environment for the period of probes influenced phenological phases of propagation and development of plants of stevia. Agrometeorological conditions of formation of yield of stevia based on interphase periods of development are analyzed, and heat and water provision of plants in the fixed interphase period is specified. Conclusions. The highest index of use of moisture in vegetative period was in Ternopol and Kiev oblasts, and quotient of water adsorption – in Kiev oblast. Statistical link is revealed of yield of overground part of stevia with the sum of efficient temperatures above 15°C.

Key words: overground part, productivity, climatic component, phase of vegetative development.
