Growth, nutrition and efficiency in the transport, uptake and use of nutrients in african mahogany

The aim of this work was to study the efficiency of nutrient uptake, accumulation, distribution and use in Khaya ivorensis  and Khaya senegalensis , in addition to aspects of growth variables and of dry matter partitioning as a function of mineral fertilisation. The experimental design was a 2 x 2 factorial scheme (with and without the addition of nutrient solution, and two species of African mahogany Khaya ivorensis  and Khaya senegalensis ). Morphological, physiological and nutritional parameters were determined in the African mahogany plants 140 days after transplanting (DAT). The greatest zinc (Zn) content was detected in the shoots of both the Khaya ivorensis  and Khaya senegalensis  plants, accounting for more than 50% of the accumulated total of the plants with added nutrient solution. Maintaining the plants of Khaya senegalensis  and Khaya ivorensis  with the use of nutrient solution provides the best conditions for nutrient use, and allows plants with excellent morphological and nutritional characteristics to be ready for the field within five months after transplanting in a shaded nursery. The most efficient uptake, transport and use of macro- and micronutrients is found in the species Khaya senegalensis  with the addition of nutrient solution.
