IDENTIFYING A SUITABLE GROWING MEDIUM AND A FERTILIZER PACKAGE FOR DRACAENA GODSEFFIANA L.CV 'FLORIDA BEAUTY' C.H. Sapumanage 1 , R.A.S Percra2 and S.E Peiris1 'Department of Crop Science, Faculty of Agriculture, University of Peradeniya 2 RoyaI Botanic Gardens, Peradeniya ABSTRACT Dracaena godseffiana Lev 'Florida Beauty' is an ornamental foliage plant which has a great demand in the export market. However, there is no suitable growing medium available to overcome its slow growth rate which is a great limiting factor for large scale production. This study inducted, to investigate the growing medium and fertilizer package which will give the best vegetative growth and to differentiate the effects ofbiofertilizer and chemical fertilizer on plant growth. • experiment, coir dust: sand in two ratios as 3:2 and 4:1 and four different types of composts with three different fertilizers were used. Hence, the experiment comprised 24 treatment combinations. The highest plant dry weight, number of leaves and root length were obtained from the medium containing coir dust:sand 3:2 ratio +garden ~ompost+ Wucksal+Blue crystal. The highest total height of shoots showed in the medium of coir dust:sand 4:1 ratio+commercial compost+N:P:K 3:1:2 ratio. Highest number of shoots were produced in the medium containing coir dusf.sand 4:1 ratio+commercial compost+ Wucksal+Blue crystal. Leaf colour and leaf glossiness did not show any significant difference among growing media and fertilizer combinations. Coir dusf.sand 3:2+garden compost+Wucksal+Blue crystal can be suggested as the suitable growing medium for D. godseffiana L. cv 'Florida Beauty'. < Key words : Dracaena godseffiana, growing media, growth performance 69
