Competition between Medicago sativa and Dactylis glomerata in mixed culture
Keywords:cultivating, competition, intraspecific
AbstractThe higs yield obtained from mixte culture of Medicago sativa and Dactylis glomerata in favourable cultivating conditions, show the superiority of this mixture in obtaining rich and constant yields. Our experiment has in view the relations established between the two species sown at different intervals on land gradually fertilized by nitrogen. The intraspecific competition for the nourishing space manifests itself with stronger intensity in the case of small distances and decreases as they increase. The presence of mineral nitrogen in the soil, for long periods, increases the competitive capacity of cocksfoot, its absence favours Medicago sativa.
