PALAVRAS-CHAVE Mogno africano Nutricao florestal Solucao nutritiva ABSTRACT: Due to the shortage of information on both mineral fertilizer and organic substrate in Khaya senegalensis, it was proposed in the current study to verify the potential of the use or not of addition of nutrient solution in the production of high quality seedlings of K. senegalensis as well as to obtain the total accumulation of macro and micronutrients in the seedlings. The experimental design was completely randomized in a factorial 2x6, being the first factor constituted by the presence and nutritious solution absence of and the second factor for times evaluation (0, 60, 80, 100, 120 and 140 days after transplanting) repetitions with four seedlings. The following growth traits (height, stem diameter and shoot and root dry mass) and seedling quality parameters (total dry mass and Dickson quality index). The addition of nutrient solution supported the increase of the determined morphological characteristics of the seedlings of K. senegalensis as well as the total accumulation of macro and micronutrients. The nutrient solution modifies the absorption dynamics of nutrients in K. senegalensis and the amount absorbed at 140 days after transplantation obeys according to the order: N>K>P>Ca>S>Mg> Fe>B>Mn>Zn>Cu.
