PURPOSE of the present study was to make a morphological analysis and calculate correlations among yield and quantitative indicators.METHODS: It was based on the blocking method in 4 replications with a plot size of 5 m2 with the following bird's foot trefoil cultivars: Targovishte 1, Alvena, Lotanova and Frilo, Polom, Bonnie, Bull. RESULTS: It was found that the share of stems in grasslands was higher than the leaves, and the degree of variation in this indicator was low. Lotanova cultivar was the most productive with a registered dry matter yield of 1061.55 kg/da. The maximum share in grassland was realized by Alvena cultivar (73.8%), and the tallest stems were registered for Targovishte 1. CONCLUSIONS: Parameters correlating with high values are dry matter yield and the percentage share of bird's-foot-trefoil in the grassland (r = 0.6816).
