Abstract

The article presents an analysis of meteorological data for the period since 1960 to 2020. Due to climate warming, there is an increase in fluctuations of agronomically important climatic indicators, such as an increase in the sum of active and average annual air temperatures and an increase in precipitation. Therefore, knowledge of regional changes in climate resources is of great importance. The following parameters were considered: the average annual surface air temperature, the sum of positive air temperatures, the sum of atmospheric precipitation, the influx of solar radiation on the earth’s surface. To model soybean yield, long-term soybean yield series for the period 1970-2020 were considered. Changing climatic conditions have an impact on crop yields, an increase in precipitation and average annual air temperature leads to an increase in soybean yields. In general, the change in agro-climatic conditions in the Middle Amur River Region at this stage of change in regional climatic parameters is relatively favorable for soybean cultivation.
