This study was carried out in the experimental nursery of the Ornamental Horticulture Department, Faculty of Agriculture, Cairo University, Giza, Egypt during the two successive seasons of 2005/2006 and 2006/2007 to investigate the response of Tecoma capensis plants grown in sandy soil amended with clay, cattle manure or poultry manure (soil amendments were added to the sandy soil at 1:5, v/v) to conventional NPK fertilizer (18 N -6 P2O5 -6 K2O) at four rates, viz., 3, 4, 5 and 6 g/plant/month. In addition, unfertilized plants were used as the control. The results showed that, In most cases, plants grown in sandy soil amended with clay and fertilized with 5 g NPK/plant/month gave the best vegetative growth parameters and chemical composition ( chlorophylls, carbohydrates and NPK content) in shoots ( leaves, stems) of Tecoma capensis plants.
