Crop biomass
Crop biomass was influenced by an interaction between crop mixture and
management, but not by crop diversity (Tables S9, S10). Under high
management intensity, crop biomass increased with crop diversity, while
under low management intensity, biomass was highest in two-species
mixtures. Notably, biomass was low in oilseed rape monocultures and in
mixtures containing oilseed rape (except linseed-oilseed rape mixtures,
Fig. S1).
