Extended Data Fig. 2: Crop plant diversity effects on seed yield and vegetative biomass of each species.
From: Diversity increases yield but reduces harvest index in crop mixtures
Average seed yield (a) and vegetative biomass (b) per species (in g m-2) of eight monocultures, 24 different 2- and 16 different 4-species mixtures planted with eight different annual crop species in 0.25 m2 plots in Switzerland and Spain. Data are mean and 1 SE based on raw data. To facilitate interpretation, data were extrapolated so that the values reflect the area of 1 m2 covered by the species in the community of interest. n = 2284 species in plots for seed yield and n = 2275 species in plots for vegetative biomass.
