Fig. 3: Differences between plant diversity effects per management intensity and management effects.

The figure shows differences and significance of the differences between a plant diversity effects per management intensity and b management effects on quality-adjusted yield (g or MJ or kg m⁻² a⁻¹) and biomass yield (g m⁻² a⁻¹). Pairs of management intensities indicate the management intensities compared to each other. The displayed numbers are the differences between the effects of the compared management intensities. Light blue, mid blue, and dark blue denote significance at the 5%, 1%, and 0.1% level, respectively (corrected for multiple comparisons), and white denotes no significant effect at the 5% level. The significance levels are based on the Wald test. Note that utilizable crude protein content was only measured for the first cut of the year, which is why we do not compare it between management intensities. The figure is based on Supplementary Tables 3–8.
