Bird’s-foot trefoil, Lotus corniculatus is a Eurasian perennial legume, popular in temperate climates for pasture or hay and silage production, and does not cause bloat in ruminants. The Romanian varieties Doru and Magurele of Lotus corniculatus, created at the Research - Development Institute for Grassland Brasov, grown in monoculture on experimental land in the National Botanical Garden (Institute), latitude 46°58′25.7″ and longitude N28°52′57.8″E, served as subjects of study. The growth and development rates, the leaf/stem ratio and the green mass productivity were studied according the standard methods. The content of crude protein, crude cellulose, ash, neutral detergent fibre (NDF), acid detergent fibre (ADF), acid detergent lignin (ADL), dry matter digestibility (DMD) and organic matter digestibility (OMD) were evaluated using the near infrared spectroscopy (NIRS) technique PERTEN DA 7200 at the Research-Development Institute for Grassland Brasov, Romania. Relative feed value (RFV) was calculated according to standard procedures. It was found that, under the conditions of the Republic of Moldova, the studied varieties of Lotus corniculatus could be harvested three mowing in the first year. The green mass yield reached 3.01-3.27 kg/m2, characterized by high content of leaves. The variety Doru was characterized by higher productivity. It was also found that the biochemical composition of dry matter of natural forage varied substantially from one harvest to another. The forage of the variety Doru contained a higher amount of crude protein (18.8-22.0 %) and minerals (11.7-13.0 %) at the first and third harvests, but the variety Magurele – at the second and third harvests. Other important quality parameters for forages are cell wall content and digestibility of dry matter. The concentrations of NDF, ADF, ADL, cellulose and hemicellulose of Lotus corniculatus also varied depending on the harvest. The whole plants of the variety Doru, harvested at the first mowing contained 458 g/kg NDF, 304 g/kg ADF, 63 g/kg ADL, 241g/kg cellulose and 154 g/kg hemicellulose, dry matter digestibility was 67.8 % and organic matter digestibility 58.9 %, but at the second mowing – 533 g/kg NDF, 359 g/kg ADF, 70 g/kg ADL, 289g/kg cellulose and 174 g/kg hemicellulose, dry matter digestibility was 56.6 % and organic matter digestibility 50.3 %. The bird’s-foot trefoil forage obtained from the first mowing, with calculated Relative feed value (RFV) 140, can be classified as good quality, but from the second mowing with RFV 106 – as fair category, and the forage obtained from the third mowing RFV 181 – supreme category. The studied varieties of Lotus corniculatus, can be grown in monoculture, as well as for reseeding and increasing the economic value of grasslands, it can also be helpful for erosion control and restoration of vegetation in wildlife habitats.
