| Abstract | ||||
| This experiment was performed in the greenhouse at the nursery of Ornamental Plants Res. and Landscape Dep., Hort. Res. Inst., ARC., Giza, Egypt through two successive seasons (2009 and 2010 aiming to find out the response of Dracaena fragrans 'Massangeana' to biofertilizers. The obtained results revealed that biofertilization treatments significantly stimulated most of the studied characters compared to control. The treatment of Dracaena with Biogien (5and10g pot-1) followed by Rhizobacterien (5and10g pot-1) gave rise to the utmost high values of vegetative growth parameters [plant height (cm), stem diameter (cm), leaves blade area (cm2), number of leaves plant-1, fresh and dry weights of leaves plant-1 (g)] as well as root length, number, fresh and dry weights. The treatment of Biogien followed by Rhizobacterien markedly improved chlorophyll a, b and carotenoids and gave the highest total carbohydrates % in leaves. Likewise, all fertilization treatments greatly raised the percentage of N, P and K in the leaves, as reached the maximum by Biogien (10g pot-1). The addition of Biogien (10g pot-1) was the best treatment for all studied parameters of Dracaena plant. In general, the dominance in all previous measurements was for Biogien followed by Rhizobacterien which gave the highest values in most cases. | ||||
