Changes in some root mass growth parameters of legume components in mixtures were studied in a pot trial in the Institute of Forage Crops, Pleven, Bulgaria (2011–2012). The following treatments were studied: Birdsfoot trefoil (100%); Sainfoin (100%); Subclover (100%); Tall fescue (100%); Birdsfoot trefoil + Tall fescue (50:50); Sainfoin + Tall fescue (50:50); Subclover + Tall fescue (50:50); Birdsfoot trefoil + Subclover + Tall fescue (33:33:33); Sainfoin + Subclover + Tall fescue (33:33:33). It was found that the root mass of legumes in the mixtures showed better development as compared with pure crops. The above-ground/root mass length in the two-component mixtures of Birdsfoot trefoil (1.469) and Sainfoin (1.992) was higher as compared with pure Birdsfoot trefoil (1.314) and Sainfoin (1.880).
