초록

This study was conducted to figure out the effect of silicate as growth stimulator on
growth of 'Pencrosss' creeping bentgrass. Creeping bentgrass(Agrostis palustris cv.
'Pencross') at the nursery of Sinwon Country Club was used. Silicate was applied at the
concentration of 0, 200×, 500×, 1.000×. Polt size was 1 by 2 meter and there were three
replications with completely randomized design(CRD).
Creeping bentgrass growth was evaluated with visual turfgrass quality, root length and
No. of tiller density(ea/㎠). Results of this study are as followings;
1. Average root length with silicate was 1.5~1.9cm longer than control. Especially, Root
length of silicate was 7~8cm in summer.
2. Tiller density with silicate was 18~22ea/㎠, 0.4~2.1 less than control. But there was
no significant difference.
3. Visual turfgrass quality with silicate was 5.0~8.3, 0.3~1.5 higher than control. But
there was no significant difference.
In conclusion, silicate might be grown as root growth stimulator of creeping bentgrass
during summer in Korea. However, this study was conducted under one year. Accordingly,
in-depth experiment should be done over several years.
