Abstract
The growth characteristics of cool season turfgrass in the seaside landfill golf courses with the single-use of kentucky bluegrass and mixed-use with kentucky bluegrass and perennial ryegrass in the coast line are as follows. Water infiltration rate was higher in the kentucky bluegrass single-use groups recorded as 95.6∼125.9cm/hr than in the roups mixed with kentucky bluegrass and perennial ryegrass recorded as 180.3∼386.2cm/hr. The surface soil hardness and the soil penetration were ranged from 16.6 to 18.0mm and from 6.0 to 7.3kg/cm$^2$, respectively. The cultivar that showed the most excellent visual quality and visual color in the kentucky bluegrass single-use groups was Midnight(KB2), whose density around the root was relatively excellent, as well. North Star(KB3) known as highly resistant to salt was the secondarily excellent cultivar. Brilliant(KB1) had visual quality of about third grade, however, it seemed profitable to develop turfgrass ground by virtue of its high density. As of April 26, 2003, when 2 weeks had passed after seeding, the visual quality was better in the groups mixed with kentucky bluegrass and perennial rye grass than in the kentucky bluegrass single-use groups. The most excellent visual color was found in Midnight(KB2)+Brightstar SLT(PR2) among the groups mixed with kentucky bluegrass and perennial ryegrass. On August 4, 2003, a disease was found from one experimental group in Blackstone(KB4) and expanded into more than 50cm of diameter.
