Distribution of potato yield (t ha⁻1) across different clustering dimensions. (a) Yield distribution and mean values for each soil cluster, highlighting the influence of edaphic conditions on productivity. (b) Yield variability across climatic clusters, reflecting the impact of agroclimatic conditions. (c) Combined effect of soil and climatic clustering on yield performance, demonstrating the potential of integrated cluster-based analysis to explain spatial yield patterns and support targeted agronomic interventions.
