RESPONSE OF MORINGA OLEIFERA TREES TO BIO-, CHEMICAL FERTILIZATION AND GROWING MEDIA

This trial was outlined at the nursery of the Ornamental Horticulture Department, Faculty of Agric., Cairo Univ. during two successive seasons of 2014 and 2015. The study was conducted to investigate the effect of different soil types (sand, clay and sand + clay) and bio-fertilizers (microbine) and chemical fertilization (NPK at 6, 8 and 10 g/pot) and the interaction between them on vegetative growth parameters of Moringa oleifera plants. The obtained results revealed that the use of clay in combination with NPK at 8 g/pot gave the highest values of plant height and stem diameter. Also, the obtained highest values of fresh and dry weights of vegetative growth resulted due to using clay or sand + clay medium in combination with microbine + NPK at 10 g/pot and NPK at 8 g/pot. The best results of root fresh and dry weights, were obtained due to the use of clay in combination with microbine + NPK at 10 g/pot and NPK at 8 g/pot.
