Experiments were carried out on the Lithuanian Institute of Agriculture's Valinava cultivated pasture during 1995-1998 on a soddy gleyic, podzolized light loam. Three lucerne varieties were investigated 'Zydrune', 'DK-122' and 'Alfagraze' in the conditions of intensive grazing and conventional cutting regimes. The findings of the three initial years showed that the Lithuanian variety 'Zydrune' produced on average 7.89-11.18 t/ha DM yield. In surpassed the American variety 'Alfagraze' in terms of persistence in the sward and its portion in DM yield both under grazing and cutting regime. In lucerne swards for grazing a slight thinning out of lucerne plants was observed. All lucerne varieties demonstrated a high competitive capacity. The sward was heavily infested with weeds. Forbs made up 4.9-6.6 in the part of sward devoted to cutting, while in the grazing part - 7.6-11.5. The experiment is being continued
