Abstract
En 中文
• Glmnet-based stacked ensemble provided robust temporal yield predictions but demonstrated limited spatial transferability, • LOYO based nested cross validation framework prevented temporal data leakage and reduce bias in yield prediction models, • SHAP analysis revealed, yield was primarily driven by soil (44.9%) followed by weather variables (29.2%), hydroclimatic indices (22.1%) and engineered biophysical interactions (3.7%). • Soil water holding capacity (WHC) and nitrogen (N) emerged as the most dominant factors affecting yield prediction across the majority of districts. • District-level analysis identified distinct regional prediction contributors, emphasizing role of context specific factors in yield prediction.
