520			_aThis study was carried out at the experimental area of the national research center, Dokki, Giza, Egypt during the two successive seasons 2013-2014 to the effect of growing media, NPK and bio fertilization on growth and chemical composition of swietenia mahagoni seedlings. The results showed that growing the plants in the mixing clay with sand gave the highest values of stem and root diameter, leaf area, fresh and dry weight of the stems and roots, chlorophyll a, b and carotenoids, total carbohydrates in leaves, stems and roots,P % in the stems in both seasons. The same media increased number of leaves / plant and K% in the leaves in the first season and N% in leaves and K % in stems in the second season. Clay soil increased plant height, fresh and dry weight of leaves, N % in the stems and roots, phosphorus in the leaves and roots and potassium in the roots in both seasons and number of leaves / plant in the second season. Also, Clay soil gave the highest values of N% in the leaves and K% in the stems in the first season. Whereas, the lowest values of all previous parameters were found with sand soil alone, except root length. Effect of fertilization treatments on the vegetative growth and chemical constituents, using 10 ml of microbien plus 6 g of NPK treatment gave the best results of number of leaves, fresh and dry weight of the stems, total carbohydrates in leaves, phosphorus in the roots, and potassium in the leaves, stem and roots in both seasons, and stem diameter, leaf area, total carbohydrates in the roots, N% in the roots, P% in the leaves and stems in the first season. while, application 20 ml of microbien and 6 gm of NPK/plant treatment recorded the highest values of root diameter, fresh and dry weight of the roots, chlorophyll a, carotenoids, total carbohydrates in the stems and N % in the leaves in two seasons, and stem diameter, leaf area, chlorophyll b, total carbohydrates in the roots, N% in the roots, P % in the leaves and stems in the second season
