Abstract

Under light grazing, the reproductive capacity of wild carrot (Daucus carota L.) was reduced, but on pastures under heavy grazing, cattle prevented regrowth and seed production of flowering plants. To simulate the effects of cattle grazing, seedlings and flowering plants were clipped at different times during the summer on natural and experimental plots on different soil textures. Plants on fine textured soils were larger in size, regenerated more rapidly, and had a higher survival rate after clipping. The most efficient time for control by a clipping treatment, determined on the basis of prevention of seed production and mortality of plants, was in the latter part of August.
