Increasing crop diversity by inclusion of competitive forbs may enhance biomass production
and sustainable biofuel production. Here we examined if one or all of three forbs (chicory,
Cichorium intybus L.; caraway, Carum carvi L.; plantain, Plantago lanceolata L.) included in
ryegrass-red clover mixtures enhanced above-and below-ground productivity, and assessed
their biofuel potentials, based on a three-year experiment with and without fertilisation as …
