Abstract
Five species of ornamental plants growing in a media containing 113.4 g and 226.8 g of Osmocote “18-6-12” (18.0-2.7-10.0, N-P-K) per 35.2 liters of artificial growing media produced a total top growth equal to plants receiving 100 to 150 ppm of N at each irrigation from a liquidsoluble fertilizer (25.0-4.4-8.4, N-P-K). Higher levels of Osmocote did not result in a significant increase in growth.Keywords
