According to the actual observations of weather conditions, which were held at the meteorological station Uman, by mathematical processing of data and its analysis on the basis of long-term values (avarage for 30 years - from 1961 till 1990), agrometeorological characteristics of 2016-2017 agricultural year was presented. A characteristic feature of this year was the increased temperature background, scarcity of rainfall in summer and air-soil drought, which began in June and continued until the end of summer. The average atmospheric temperature of the agricultural year amounted 9,0°C, it was by 1,6°C higher than the long-term average. In the cold season (December - March) sum excess was 2,4°C, and for the warm season (April - September) 12,2°C. The total rainfall for the year – 524,2 mm, it is on 17,2% less than normal. Therefore, the long-term summer rainfall deficit was a limiting factor for plants growth and development.
