Lucerne has the potential to improve feed autonomy on livestock farms. Small-scale experiments were carried out over 3 years at three constrasting sites in Belgium with a view to optimising lucerne use. Results obtained for grass-lucerne associations were compared with those obtained for pure stands of lucerne, cock's foot grass, tall fescue, and Alaska brome. Annual production and nitrogen content were higher in pure-lucerne and grass-lucerne associations than in pure-grass stands, whose production levels were greater in the spring. Lucerne production and contribution to overall yield were lower at the Ardenne site (where conditions were colder and more humid and the soil was more acidic) than at the other 2 sites. At all 3 sites, pure-lucerne and grass-lucerne associations were more productive than pure-grass stands during periods of drought
