The paper presents the results of two years of research conducted in eastern Serbia (2007-2008). Tests were conducted with domestic varieties K-14, which was developed at the Institute for Forage Crops, Krusevac. At two different densities B1 (the inter-row distance of 12.5 cm and 15 kg ha-1 seed) and B2 (25 cm row spacing and 7.5 kg ha-1 seed) following components of yield were observed: plant height (cm), number of generative stems, inflorescence length (cm), number of branches in umbel; seed yield (kg ha-1) The following parameters of seed quality were: 1000 seed weight (g), germination energy (%), germination of seeds (%). Interdependence of the traits was determined by simple correlation coefficients (r). The highest seed yield was recorded in density B2. Variability of seed yield was high (CV = 49.9%), because influence of year and plant density. Seed yield achieved the strongest positive correlation (p ≤ 0.01), with generative stems (r=0.994). Also strong dependence was found between plant height and number of generative stems (r=0.977).
