Abstract: The Brazilian Cerrado has numerous fruit species with economic potential for exploitation in commercial cultivation. In this context an experiment was developed with jatoba-do-cerrado seedlings at the State University of Mato Grosso do Sul / Aquidauana-MS, from October 29(th), 2009 to February 25(th), 2010, in a greenhouse covered with polyethylene film of 150 mu m, light diffuser, with thermal reflective screen of 50% of shading under film, front and side with monofilament screen of 50% of shading and the nursery with black monofilament screen of 50% of shading and closing of 45 degrees. In these environments the plants were grown in plastic pots of 5.0 L filled with 100% of soil, 100% of organic compound and levels of 10, 20, 30, 40, 50, 60, 70, 80 and 90 of organic compound added to the soil. The experiment was carried out in a completely randomized split-plot scheme with five replications. In both environments, plants have emerged more rapidly, higher growth and more biomass accumulation in the substrate without addition of organic compound. In this substrate the plants developed better in the greenhouse. The seedlings did not show positive response at the organic compost levels. The organic compound used increased the pH of the substrates, showed excess of certain nutrients and did not contribute to an effective seedling growth.
