Abstract (Summary)
Effects of Three Clipping Managements on Growth and Production of a Kentucky Bluegrass-Clover Sward Beverly Sedon The effect of three clipping managements on the growth and production of Kentucky bluegrass was investigated at the West Virginia University Livestock Farm. Herbage accumulation, botanical composition, leaf extension rate (LER), leaf appearance rate (LAR), and tiller density were observed. The sward was clipped to three heights, 2.5, 5.1, and 7.6 cm, from a recovery growth of 13 to 15 cm. Nitrogen was applied in split applications twice a year at three rates (0, 80, and 160 kg N ha-1). Herbage accumulation and growth rates were higher in 2000 than 1999. Rainfall was higher in 2000 than in 1999. Low cut plots produced the most herbage. The proportion of legume increased from 1999 to 2000 and the highest proportion was in the low and high cut plots. Highest LER and LAR occurred in the spring and late summer/early fall. Tiller density was highest when nitrogen was applied.
