Fairway Height Kentucky Bluegrass Cultivar Trial - Established 1998
Nick E. Christians and Barbara R. Bingaman
This is the second year of data from the Fairway Height Kentucky Bluegrass Cultivar Trial established in the fall of 1998. Data collection began after the cultivars were fully established in April, 1999. The area was maintained at a 0.5 in. mowing height. Four bluegrass cultivars were included. The cultivars were maintained with 4 lbs of N/1000 ft2/growing season. Fungicides are used as needed in a preventative program. Herbicides and insecticides were applied as needed.
Visual quality ratings were taken from April through October 1999 (Table 1). Visual quality was assessed using a 9 to 1 scale with 9 = best, 6 = lowest acceptable, and 1 = worst quality.
