The aim of this study was to determine the best substrate type and light conditions for the cultivation of
seedlings of
Tocoyena formosa
(Cham. & Schltdl.) K. Schum. Seeds were planted in Styrofoam trays under
70% shading. Three months after emergence, the seedlings were selected and transplanted in 4-L pots, in
two types of substrates: 50% dystroferric Red Latosol + 50% sand (TA) and 50% dystroferric Red Latosol +
25% sand + 25% semi-decomposed chicken manure (TACF). After transplanting, the seedlings were placed
under three conditions of shading (30, 50 and 70% shade) and full sun (0% shade). After acclimation, the
physiologic quality of the seedlings was determined monthly, by analysis of growth and Dickson quality
index, for 90 days. The experiment was carried out using a randomized block design in a 2 x 4 x 4 factorial
scheme (substrate x shading x age of seedling), with three repetitions of three seedlings. There was greater
growth and quality of the seedlings in the substrate soil + sand + chicken manure and under conditions of
30% shade and full sun. It is concluded that for the production of seedlings of
Tocoyena formosa, the best
conditions are 30% shade and full sun for light and TACF for substrate.
