From: Yield trends, variability and stagnation analysis of major crops in France over more than a century
Temporal correlation (Pearson’s r) of yield residuals (based on nationally aggregated yield time series) between crops; only significant correlations are plotted (p < 0.05). Values above the diagonal show correlations, while numbers in grey boxes below indicate p-values. Colour coding represents correlation strength, from green = low to red = strong. For each pair of crops the maximum time frame where both time series contain data is used (SI Table 1).
