| Abstract | The objectives of this study were to determine how eight seasonal defoliation patterns affect regrowth of dry matter yield and basal diameter of mesa dropseed (Sporobolus flexuosus [Thrub.] Rhydb.) and black grama (Bouteloua eriopoda [Torr.] Torr.); determine how these defoliation patterns affect the reproductive potential of black grama; quantify seasonal phenological stages of growth in both species; and interpret the data in terms of management application. Regrowth and basal diameter of both species clipped to remove 30 percent the first year during vegetative growth had increased after two growing seasons. Therefore, for continued forage production, light use prior to floral development is recommended. Regrowth, basal diameter, and stolon numbers increased over two growing seasons in black grama plants clipped to simulate light use at dormancy. Therefore, light use of black grama during the winter is encouraged. |
