Variability of Spring Wheat Yield Depending on Weather Conditions

The article publishes the results of research conducted over a three-year period in a field stationary experiment located in the fields of the Department of Agriculture at the Tambov Research Institute of Agriculture, a branch of the Federal Research Center named after I.V. Michurin. The article discusses the impact of weather conditions on the variability of the yield of the Daria spring wheat variety, as well as on the yield increases depending on the use of mineral fertilizers. The article calculates the hydrothermal coefficient and uses mathematical formulas to determine the correlation between the hydrothermal coefficient and the yield, as well as the yield increases.
