Mangaba (Hancornia speciosa Gomez) seedlings were transplanted eleven months after emergence to the following substrates: soil (Oxisol), soil + 33% calcined sugar-cane bagasse, and soil + 66% calcined sugar-cane bagasse, with and without lime and fertilizer. At 70, 100 and 130 days after transplanting, plants were evaluated for height and number of leaf pairs. At the end of the experiment – 130 days – roots and aerial part dry matter were weighed. The addition of 0.5 kg.m-3 of 10-10-10 fertilizer to the soil was the best treatment. Root dry matter was slightly higher than aerial part dry matter on some treatments. Roots have developed more than aerial parts. In general, substrates with pH values between 5.2 and 5.5 promote higher growth of mangaba seedlings, but those with pH between 6.0 and 6.8 cause seedling growth reduction.
