#### Abstract

The objective of this research was to produce sod by box seeding for zoysiagrass or by vegetative propagation for zoysiagrass and manilagrass.1 Various ratio of peatmoss to sand(v /v) were prepared to find idea[ medium for fast and light weight sod production. Then, the days required for sod formation, the effect of growth regulators on the growth of turfgrass, and the various storage methods for winter keeping of sods were also investigated. 1.The mixed medium of sand and peatmoss(v /v, 1 : 2) showed more biomass production than that of sand. 2.In comparison of seeding rate of zoysiagrass, the amount of log /$m^2$ was most effective in the fast and dense sod formation. The amount of 20g /$m^2$ also showed fast sod formation. But, it resulted in weak plant and less tillering. During April to June, about 100 days were required to form sod with seeding rate of 5g /$m^2$ regardless of seeding time. Whereas 80 days were required to form sod in the rate log /$m^2$, which was 20 days shorter than that of 5g /$m^2$. 3.More than 85% of shoots in sod stored in field or plastic house during the winter time resumed the growth in good appearance after transplanting. The whole covering of ground with sod resulted in less weeds and faster formation of lawn. 4.Vegetative propagation of manilagrass showed about 7 to 15 days faster formation of sod than that of zoysiagrass. Application of GA increased shoot growth and BA increased the total number of tillering. However, the effects of the combined application of GA and BA were negligable.
