a The correlation between the legume pre-crop effect on main crop yield and the N fertilizer rate depending on crop diversity. b The correlation between the legume pre-crop effect on main crop yield and crop diversity depending on N fertilization (−N, without N fertilizer; +N, with N fertilizer). Colored lines represent the average diversity- or fertilization-specific responses, with their bootstrapped 95% confidence intervals indicated by shading. Crop diversity is defined as the number of crop species × number of crop functional groups × number of crop species per year. Linear mixed-effects model fit tests used Satterthwaite approximations for denominator degrees of freedom. The significance (P) is presented for each term tested.
