Prostrate vs. Common Dallisgrass Under Different Clipping Frequencies and Fertility Levels1
- Richard H. Hart and
- Glenn W. Burton2
Prostrate and common daffisgrasses were fertilized with 0, 50, 100, 200, or 400 pounds of nitrogen per acre, and harvested every 2 or 4 weeks. Prostrate consistently produced higher forage yields than common, with the difference between varieties more marked at higher nitrogen levels and when cut every 4 weeks. Yields of both grasses were higher when cut every 4 weeks than when cut every 2 weeks, and increased with increasing rates of nitrogen, up to 400 pounds per acre. Higher yields of prostrate were due to faster growth in June, July, and August, with little difference between varieties before or after this period. Crude protein content of both grasses increased with increasing nitrogen and more frequent cutting, with no significant difference between grasses. Forty months after establishment, there were fewer weeds in prostrate dallis than in common. In view of these results, prostrate dallisgrass is recommended for light, poorly drained soils in the South when seed becomes commercially available.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
