Resumo
In recent years, in the Brazilian Savannah, there is a growing interest in the cultivation of tree species, which stand out for their environmental and commercial importance. The objective of this work was to evaluate the initial growth of African mahogany (Khaya ivorensis) plants on substrates and irrigation levels and to select the productive characteristics that result in ideal conditions for production .The experiment was installed in a randomized block design, with four replications, in split-plot, in the scheme 5 x 3, plots composed of five daily irrigations levels (6, 8, 10, 12, 14 mm) and four subplots substrates: S1 - 100% OXISOL RED; S2 - 50% OXISOL RED and 50% sand and S3 - 45% OXISOL RED, 45% sand, and 10% of tanned. The evaluated characteristics were plant height, stem diameter, number of leaflets, root system length, dry matter mass of roots, dry matter mass aerial part, dry matter mass seedling, ratio between roots dry matter mass and aerial part and seedling quality. The depth irrigation of 6 mm dia-1 was the most indicated and the S1 substrate provided the highest quality to the African mahogany, under the conditions in which the study occurred.
