A pot experimental trial was carried out during 2015/2016 and 2016/2017 seasons to study the effect of 18 treatments was represented by the combination between six different growing media, i.e. clay + sand, clay + sand + compost, clay + sand + peat moss, clay + sand + perlite, clay + sand + compost+ peat moss +perlite and compost + peat moss + perlite (1:1:1 by volume) and three chemical fertilization rates of kristalon fertilizer at 0.0, 4 and 8g/pot on the growth and chemical composition of Dypsis cabadae palm plants. Results showed that growing Dypsis cabadae palm plants in a mixture medium contained compost + peat moss + perlite (1:1:1 by volume) supplemented with kristalon fertilizer at 8g/pot produced the tallest plant, the highest values of fresh and dry weights of leaves and stem /plant, stem length, root length (cm) and fresh and dry weights of roots/plant, the highest leaf total chlorophylls, total nitrogen, phosphorus, potassium and total carbohydrates content as well as the highest leaf auxin and gibberellins content. Besides, the highest values of number of leaves/plant, stem diameter, plant width, No. of root / plant and cytokinins contents as well as the lowest leaf abscisic acid content. In addition, the greatest show value of Dypsis cabadae palm was recorded by using the mixture media of clay + sand + compost + peat moss + perlite and Kristalon fertilizer at 8g/pot (8g/pot) in both seasons. Conclusively, growing Dypsis cabadae palm plants in a medium contained compost + peat moss + perlite or a medium composed of clay + sand + compost+ peat moss +perlite and supplemented with kristalon fertilizer at 8g/pot produced the best growth and quality of this plant |
