Selective logging of forests has caused the densities of Hymenaea oblongifolia Huber to be significantly reduced in the Choco department. Therefore it is necessary to advance in studies that contribute to their management. The objective of this research was to evaluate the germination, the initial growth and the survival of this species using unimproved botanical seeds. In each one of the environments: free exposure solar LS and under shade BS, a completely randomized design was used, with factorial arrangement, formed by 12 treatments and three repetitions of four seeds each. Two combinations of organic substrates were used in the presence of a control (alluvial sand). For the variables germination and height no significant statistical differences were detected; While for diameter if differences were presented. The germination values were higher in LS (67.4%) than BS (65.3%), presenting the same trend for survival (SL = 82% and BS = 81,2). On the contrary, for diameter and height the best behavior of the seedlings was presented BS with values of 0.38 cm and 17.94 cm respectively. It is recommended to germinate the seeds of H, Oblongifolia to free solar exposure and pass the seedlings to shade for their initial growth in the nursery
