Assessment of the influence of hydrothermal conditions on the yield of winter wheat under different agricultural technologies in the grain-fallow-row crop rotation

Abstract

The article considers the influence of hydrothermal conditions of the Kursk region on the yield of winter wheat grain under different agricultural technologies. The Central Chernozem region differs from other regions of Russia and over the past decades there has been an increase in temperature, the amount of precipitation exceeds long-term data and is unevenly distributed by seasons. The current situation creates a certain climatic risk of crop loss. During the research period, it was found that the hydrothermal regime is unstable over the years and it largely determines the yield of winter wheat for various types of agricultural technologies, especially in 2017–2018 and 2018–2019. The paper shows that the spring reserves of productive moisture did not affect the yield. The correlation analysis allowed us to assess the degree of correlation between the yield of winter wheat and hydrothermal factors.
