Frequency and Severity of Defoliation of Crownvetch Stems by Grazing Sheep¹

Agronomy Journal, 1970
AbstractWhen crownvetch (Coronilla varia L.) was grazed by sheep (21 sheep/ha for 9 days), the probability that a leaf‐bearing stem would be grazed on any day was .134. Over O% of the leaves were removed from nearly all grazed stems, but 21 to 40, 41 to 60, 61 to 80, and 81 to 100% of the leaves were removed from equal numbers of stems. Stem tissue was
