Utilization and economic value.

An exellent forage crop with high nutritive value, equal to Trifolium pannonicum. Characterized by longevity ( in culture can be used up to 10 years). Hairiness of the plants doesn't limit the good palatability by animals. Excellent plant for honey production. Risk of bloat. Good seed producer. Characterized by high winter hardiness and high drought, pests and insects resistance.
