Avaliações morfológicas de mudas de Cedro australiano submetidas a diferentes doses do fertilizante osmocote plus®/Morphologic evaluations of Australian Cedar submitted to different doses of osmocote plus® fertilizer

The Australian Cedar (Toona ciliata M. Roem) is an exotic specie that has been highlighting due its great potential in brazilian commercial silviculture for presenting high growing taxes. This work aimed evaluate the development of seedlights of Toona ciliata when submitted to differets doses of fertilizer. The experiment was developed in random blocks, being the respective doses of Osmocote Plus®: 0; 3; 6; 9; 12 kg m^sup -3^ of substrate. The fertilizer of controlled solubilization Osmocote Plus® in formulation of 15-09-12, in all dosing, afforded the increase in morphologic characteristics evaluated. Thus, the fertilization of Australian Ceder with Osmocote Plus® provided the best parameters evaluated, in doses ranging of 7,5 to 8,5 kg m^sup -3^ of substrate. So it is porssible infer that an ideal dose of Osmocote Plus® fertilizer in formulation of 15-09-12 for fertilization of Australian Cedar seedlights, is of 8,0 kg m^sup -3^ of substrate.
