In this paper, yield and quality of forage following species of forage legumes were evaluated with regard to precipitations: lucerne (Medicago sativa L.), red clover (Trifolium pratense L.), white clover (Trifolium repens L.), kura clover (Trifolium ambiguum M.), alsike clover (Trifolium hybridum L.) and birdsfoot trefoil (Lotus corniculatus L.). The trial was sown in the spring of 2008, evaluated in the period 2009–2011. Analysis of samples was performed with the apparatus NIRS 6500. Following parameters were evaluated: production of dry matter, energy concentration (NEL), contents of fibre and crude protein. The highest three year yield average was measured for lucerne (15.01 t.ha−1), followed by red clover group (9.3–11.8 t.ha−1). Kura clover gained the lowest yield (1.97 t.ha−1). The average crude protein contents (g.kg−1) were: lucerne 211.47, red clover group (184.3–194.8), white clover group (229.1–238.7) and birdsfoot trefoil (204.2). The obtained results indicated that lucerne responded at best to periods of drought. Although the production of dry matter decreased in periods of drought, the canopy of stands remained to be complete in contradistinction to white clover, which partly disappeared from the stand. Red clover and alsike clover disappeared from the stand during the trial.
