QUALITY OF ALFALFA(Medicago sativa L.), IN THE FIRST YEAR OF VEGETATION

In a bifactorial experience, during March-October 2010, at the Research Station Ezăreni from Iasi, we studied alfalfa in the first year of vegetation, analizing the effect of seed inoculation with symbiotic bacteria Rhizobium meliloti Dangeard and the effect of fertilization on the dry matter (DM) yield, the amount of crude protein per hectare, the leaves/stems ratio and the forage quality indicators (CP - crude protein content, NDF - neutral detergent fiber content, ADF - acid detergent fiber content and RFV - relative feed value). The results showed that under experimental conditions, the interaction of two factors led to DM yields ranging from 5.04 to 7.75 t·ha -1
