Influence of Spring Mowing on Reseeding and Productivity of selected Annual Clovers in a Grass Sod1

  1. W. E. Knight2

Abstract

Abstract

In a 3-year experiment, we studied the effects of three spring mowing treatments on reseeding of selected varieties of crimson, arrowleaf and subterranean clovers grown in a coastal bermudagrass (Cynodon dactylon (L.) Pers.) sod. Mowing on April 25 prevented satisfactory reseeding of crimson clover (Trifolium incarnatum L.) and greatly reduced reseeding of arrowleaf clover (Trifolium vesiculosum Savi.). Clipping on May 25 prevented effective reseeding of arrowleaf clover but provided best reseeding of crimson clover. Subclover (Trifolium subterraneum L.) reseeded well under all three spring mowing treatments. Careful grazing management of crimson and arrowleaf clovers will be required after April 1 if reseeding is desired. Under conditions of spring drought, overgrazing may reduce regrowth and seed production and cause stand failures in the succeeding year. Properly managed winter-annual clovers not only produced forage of high quality in the winter and spring, but also increased production of the associated grass.
