Analyzing the Impact of Agrometeorological Factors on Winter Rye Yield in the Central Non-Black Soil Zone

摘要

Agrometeorological conditions in Central Non-Black Soil zone and their impact on winter rye yield in the trial area and under production conditions are determined using the methods of the correlation, regression, and factor analysis. According to the obtained data, the temperature factor has the greatest impact on yield whereas the moisture regime is the secondary factor. The intensification of anthropogenic impact on winter rye agrocenosis causes the significant reduction of the impact of adverse agrometeorological factors on winter rye yield. There is the potential for increasing crop yield by weakening the negative effects of agrometeorological factors and using heat and moisture resources rationally.
