Weather Stress During Key Growth Stages Drives Yield Variability Under Deficit Irrigation: A Six-Year Study

This study unveils the key factors influencing crop yield and variability under deficit irrigation, focusing on the combined impact of water stress and weather conditions from the jointing to flowering stage. Analyzing data from a six-year study, we demonstrate the significant influence of weather stress during this critical growth period on yield and yield variability. Our research identifies specific weather factors that contribute to these variations, providing valuable insights for optimizing irrigation strategies and enhancing crop resilience under water-limited conditions.
