| Abstract | ||
| This investigation was carried out in the open field at the nursery of Antoniades Res. Branch, Hort. Res. Inst., Alexandria, Egypt during 2009 and 2010 seasons to study the effect of soil dressing with rhizobacterien, nitrobien and biogien commercial biofertilizers on growth and chemical composition of 6-months-old transplants of Ficus binnendykii (Miq.) Miq. cv. "Amstel Queen" cultivated in 20-cm-diameter clay pots filled with about 2.5 kg of sand + clay mixture (1:1, v/v), when added at the rates of 0, 3 and 6 g/pot, five times with one month interval, and to detect how far these biofertilizers can replace the chemical fertilization with NPK compound fertilizer at the rate of 2 g/pot. The obtained results indicated that all fertilization treatments examined in this study significantly improved all vegetative and root growth parameters (plant height (cm), stem diameter (mm), No. branches and leaves/plant, leaf area (cm2) and fresh and dry weights (g) of leaves, stem and roots), as well as the active constituents in the leaves of the treated plants (chlorophyll a, b and carotenoids (mg/g F.W.) and the percentages of total carbohydrates, N, P and K). the dominance in all previous measurments was for the dressing with biogien at 6 g/pot treatment, which gave the utmost high means compared to those of control, NPK and all other biofertilization treatments in the two seasons. It was also noticed that biofertilizers treatments, especially at the high rate (6 g/pot) recorded better results than NPK treatment in most cases of both seasons. So, in order to get the best growth and higher content of active constituents of 6-months-old transplants of F. binnendykii cv. "Amstel Queen" grown in 20-cm-diameter clay pots, it is preferable to fertilize them with biogien at the rate of 6 g/pot, proved to added as soil dressing, five times with one month interval. | ||
