Goal. To assess weather conditions and establish the patterns of their impact on the yield of spring barley for different energy saturation technologies for its cultivation in the Northern part of the Right Bank Forest-Steppe of Ukraine. Methods. Field — to carry out long-term experiment in 4 repetitions; measuring and weighing — to account for crop yields; comparative — to calculate the dependence of crop yields on weather factors; statistical and correlation. Results. The tendencies of change of weather conditions for 1999–2018 were analyzed and the regularities of their influence on the yield of spring barley in the conditions of the Northern part of the Right-Bank Forest-Steppe were established. According to the results of 20-year experimental data based on correlation regression analysis, mathematical models were created that reproduce the dependence of spring barley yield, which was grown by technologies of different intensity, on the complex weather conditions of the growing season. The greatest dependence of crop productivity on the conditions of April moistening and the temperature regime of May is shown. Conclusions. In the Northern part of the Right-Bank Forest-Steppe there is a significant fluctuation of weather conditions, namely: an increase in temperature and a decrease in rainfall during the growing season and their instability over the years. Analysis of correlations between spring barley yield and weather conditions under different cultivation technologies shows that the conditions of April moisture and temperature in May had the greatest influence on crop formation. |
