Bruciatura e presenza di sulla nei pascoli seminati con questa specie

Effects of burning on sulla (Hedysarum coronarium L.) occurence in pastures sown with this species. Effects of burning on sulla (Hedysarum coronarium L.) density, biomass and contribution to total yield were examined over a three-year period on four different aspects of pastures originally sown with this species. Fire increased sulla's occurrence on all aspects examined except in the aspect with wet soil for long time, and showed a greater effectiveness on southern slopes than on norther ones. In the latter differences among the examined aspects did not occur.
