Effects of Different Topdress Materials on Growth and Qualities of “TifDwarf” Green
National Pingtung University of Science ＆ Technology Department of Plant Industry
In this experiment we applied five different topdressing materials (sand, sandy soil, coir, sawdust and peat) twice on TifDwarf green to test their effects on growth and qualities of the turf. The results showed that coir can significantly promoted shoot growth and increase turf density. All topdress treatments showed long-term effect of increased shoot growth and density. Organic topdress materials enhanced turf color and sandy soil improved smoothness. Turf managers can select appropriate materials for periodic topdress procedure to maintain and promote turf qualities.
Key word：green, topdress materials, growth, quality。
