EFFET DE LA PRESENCE DE LA FLEOLE DES PRES SUR LA SURVIE A L’HIVER DU TREFLE ROUGE

Abstract

The influence of timothy (Phleum pratense L.) on winter survival of red clover (Trifolium pratense L.) was studied in an experiment conducted in 1984–1985 and repeated in 1985–1986. The results indicate that the presence of timothy can help to improve red clover persistence. When the winter was favorable to the survival of legumes, the red clover population was higher in pure than in mixtured clover populations. However, when the winter was unfavorable to legumes, the red clover population was higher in populations mixed with timothy than in a pure clover population.Key words: Red clover-timothy mixture, winter survival, stand, yield
