AGRICULTURAL METEOROLOGY TERMS 2017–2018 AGRICULTURAL YEAR FROM DATA OF WEATHERSTATION UMAN

Abstract

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 2017–2018 agricultural year was presented. A characteristic feature of this year was the increased temperature background, scarcity of rainfall in summer and air-soil drought, sufficient amount of precipitations. The average atmospheric temperature of the agricultural year amounted 9,7 °C, it was by 2,3 °C higher than the longterm average. In the cold season (December - March) sum excess was 5,9°C, and for the warm season (April - September) 18,7 °C. The total rainfall for the year – 680,6 mm, it is on 7,5% anymore normal. Therefore there were favourable terms for a height anddevelopment of agricultural cultures.
