| Abstract | ||
| A greenhouse trial was conducted at Horticulture Research Institute, Giza Egypt during 2005 and 2006 seasons to study the separate and the combined effects of different growing media [peatmoss, peat+sand (1:1 by volume) and peat+ sand + clay (1:1:1 by volume)] with the commercial liquid organic fertilizer containing humic acid (actosol®) at four levels [0, 5.0 cm3/L as foliage spray, 10.0 cm3/L as soil drench and 5.0 cm3/L spray + 10.0 cm3/L as drench] on growth and chemical composition of Schefflera (Brassaia actinophylla). The results showed that the peatmoss was superior than the other media in plant height, number of leaves/plant, stem diameter, fresh and, dry weights of foliage and roots as well as leaves content of N, P, K, Zn, Fe and Mn. Humic acid treatments revealed significant effect on plant parameter, which reached its maximum due to the use of (actosol®) humic acid as foliage spray plus soil drench. It could be recommended to use the peatmoss medium and fertilize the plants every two weeks with humic acid [actosol®] at the rate of 5.0cm3/L foliage spray+ 10.0 cm3/L soil drench, to obtain high quality plants. | ||
