The influence of the degree of climate continentality on the productivity of agricultural production

Abstract

This article provides estimates of the influence of the degree of climate continentality on the yield of spring crops and on the quality of spring wheat grain. The analysis of variance was chosen as a research method, which makes it possible to assess the significance of the influence of one quantity on the variability of another. As a result of the study, it was found that the degree of climate continentality affects the formation of spring wheat yields ambiguously. For areas where there is an increase in the degree of climate continentality, there is a weak negative correlation between continentality and the yield of spring wheat. For grain-sowing areas, in which no increase in the degree of continentality was observed, there is a weak positive correlation between the yield of spring wheat and this characteristic. It was found that the increase in the degree of continentality reduces the yield, but improves the quality of the grain. Correlation dependencies are estimated at -0.25 and 0.62, respectively. It is shown that the degree of climate continentality determines the quality of grain. The contribution of the degree of continentality to the formation of protein content in spring wheat is estimated at 48%.
