ESTABLISHMENT OF BERMUDAGRASS SEEDED WITH ANNUAL RYEGRASS

IN A SERIES OF TESTS, THE RESEARCHERS WERE ABLE TO DETERMINE THAT THERE WERE NO SUBSTANCES IN ANNUAL RYEGRASS TO RETARD GERMINATION OR INHIBIT GROWTH OF BERMUDAGRASS WHEN THE FORMER SPECIES IS USED AS A COMPANION CROP FOR QUICK STABILIZATION. THE STUDY INDICATES, HOWEVER, THAT ANNUAL RYEGRASS IS EXTREMELY COMPETITIVE AND THAT GROWTH OF BERMUDAGRASS WAS REDUCED AS THE RATE OF RYEGRASS WAS INCREASED. GENERALLY, THE BEST PLOTS OF BERMUDAGRASS WERE ESTABLISHED WHEN SEEDED ALONE. IN MANY INSTANCES THOUGH, IT IS NECESSARY TO ESTABLISH A QUICK COVER IN ORDER TO CONTROL EROSION, HENCE THE NEED FOR ADDING ANNUAL RYEGRASS. TREATMENT OF ANNUAL RYEGRASS WITH DALAPON AND PARAQUAT HERBICIDES, AND/OR MOWING, TENDED TO REDUCE OR ELIMINATE THE COMPETITION. MOWING SLOPES OFTEN CAUSE RUTTING TO SUCH A DEGREE THAT THIS METHOD OF CONTROL WAS UNSATISFACTORY. WHEN A QUICK COVER IS NOT ESSENTIAL, OR WHERE A SURFACE MULCH WILL AFFORD PROTECTION FOR A RELATIVELY LONG PERIOD, BERMUDAGRASS SHOULD BE SEEDED ALONE. IF A QUICK COVER IS REQUIRED, ANNUAL RYEGRASS CAN BE SEEDED AT REDUCED RATES AND ITS AGGRESSIVE TRAITS CONTROLLED THROUGH THE USE OF HERBICIDES OF BY MOWING. TABLES, CHARTS AND A LITERATURE REVIEW ARE INCLUDED TO SUPPORT THE AUTHOR'S RESEARCH FINDINGS. /BPR/
