초록

Managing a mixture of zoysiagrass with tall fescue has been proposed in transitional
zone as a practical practice to combine the advantages of the two species and
compensate the limitations. To manage the mixture is a challenge because two species
are involved. The objective of this study was to determine if zoysiagrass/tall fescue
mixture can be maintained with proper mowing and fertilization under simulated sport
traffic at an acceptable quality level. Zoysiagrass was seeded in June and tall fescue
was overseeded in August 1996. In November 1996, zoysiagrass coverage was 62.36,
29.88, and 30.02% for 0, 50, and 100 Kg ha-1 N rates, respectively. At the same
time, zoysiagrass coverage was 23.53, 41.95, and 57.40% for the mowing heights of
6.5, 5.0, and 3.5 cm, respectively. Zoysiagrass and tall fescue coverage in July 1997
was showing the same trend as in the late season of 1996 although the differences
were not as big. There were significant interactions between N fertilization rates and
mowing heights. In November 1998, the zoysiagrass coverage was different among the
two tall fescue variety mixtures, 21.68, and 32.25% in ‘Arid’ and ‘Grasslands Garland’,
respectively. Zoysiagrass coverage was favored in lower mowing height, lower N rates,
and lower traffic. Interaction effects on zoysiagrass were found between tall fescue
variety and nitrogen rate, tall fescue variety and mowing height, and traffic and
nitrogen rate. Zoysiagrass shoot density was 7.42, 25.47, and 58.95% for mowing
heights of 6.5, 5, and 3.5 cm, respectively; and it was 47.27, 20.27, and 26.26% for N
rates of 0, 50, and 100 Kg ha-1, respectively in 1998. The effects on zoysiagrass shoot
density from the interaction of N rate and tall fescue variety was significant in 1998.
Shoot density responded to the N rate, mowing height, and traffic differently from the
ground coverage, indicating that shoot and leaf growth have different adaptation
strategies.
