From: European soybean to benefit people and the environment
Soybean crop performance across Europe and its potential growing regions (16 clusters with similar outcomes for maturity groups 0000 to III). Clusters L to P were shaded dark grey because soy cannot complete its growth cycle in these regions. (A) Median and interquartile ranges of potential (y-axis) and rainfed yields (x-axis) for the maturity group with the largest yield within each region. Interquartile ranges for yields originate from temporal and spatial variation in weather, site-to-site variation in soil properties, and uncertainty associated with satellite-derived soil water initial conditions. Regions were assigned to crop improvement strategies: breeding for cold-tolerance in cool climates (blue shade), agronomic optimisation (green shade), and improving drought tolerance (brown shade); dashed line is the 1:1 regression line. (B) Geographical extent of each cluster; a bar plot inset is labelled with maturity group with the largest median rainfed and/or potential yield, and the bar is coloured cyan according to the proportion of years the maturity group successfully reached R7. For insets with two bars, the upper bar represents the maturity group with the largest median rainfed yield, and the lower bar represents the maturity group with the largest median yield potential. Insets with one bar indicate the same maturity group had the largest median potential and rainfed yields. The proportion of years failing to achieve R7 is coloured red, and the proportion of years with crop harvest success are coloured in light blue. The map was created using Python 3.10.0 (https://www.python.org/downloads/).
