The purposes of the research - to evaluate the influence of weather conditions on the productivity of cereal grain crops (winter wheat and spring wheat, spring barley), depending on the saturation of crop rotation of grain crops from 57 to 100% in the Left-bank part of the Forest-steppe of Ukraine. To develop a comprehensive model of the productivity formation of grain cereal crops in different crop rotations for modern agrometeorological risks in the Left-bank Forest-steppe of Ukraine. The stated goal is realized by creating mathematical models based on correlation-regression analysis on the dependence of winter wheat and spring wheat and spring barley on the meteorological conditions. The research was carried out in a long-term stationary experiment on typical low-humus chernozem of the Panfilska research station of NSC "Institute of Agriculture of NAAN" in different rotation crop rotations. Soil - chernozem is a typical, shallow, low-humid, large-pebble-loamy loam. The generalization of long-term indicators of meteorological conditions during the growing season of grain cereal crops for the last 77 years is given. The statistical analysis of the meteorological data of selected months showed that the temperature indexes had the highest variability in April (V = 34.1%) and September (V = 19.8%) in the other months, the variation of the indicators was average (V = 10.5-16, 5%). It was established that the yield of spring crops (wheat and barley) was more dependent on the complex weather conditions of May and June, and winter wheat was dependent of May, June and July weather conditions. During these months the influence of weather conditions on yields reached 60-70%. The influence of weather conditions on grain quality during vegetation varied from 13.2 to 53.4%.
