This study aims to evaluate how different crop rotation systems influence soybean yields under varying climate conditions over a decade.
Tested five cropping systems from 2008–2017, including soybean monoculture and rotations with maize, winter wheat, and sugar beet.
Measured soybean yield under various fertilization regimes and correlated yield with climate factors.
Conducted regression analysis to assess the relationship between rainfall, temperature, and yield performance.
The highest average yield was 2.75 ± 0.20 t ha −1 in a fertilized 3-year rotation; the lowest was 1.21 ± 0.13 t ha −1 in unfertilized rotations.
Rainfall in June had a strong positive correlation with yield (r=0.65, p<0.01), while August temperatures negatively impacted yield (r=−0.72, p=0.05).
Growing degree units increase of 1 °C resulted in a yield decrease of 1.57 kg, emphasizing temperature sensitivity in soybean production.
