Mimosa bimucronata (DC) O. KTZE. (maricá), belong to the family Fabaceae is a forest species found in Latin America. This species has been used in landscaping, reforestation and restoration of degraded areas and permanent preservation. The present work aimed to verify the effect of the position of the seed and the depth of sowing in the emergence and initial growth of seedlings of M. bimucronata. The experiment was carried out in a completely randomized design with four replications including 25 seeds per treatment. Different positions of the seeds were used in the sand substrate: downward facing (HB) thread; facing the side, forming an angle of 90 ° to the imaginary axis with the substrate (HL); and upward facing wire (HC), at seeding depths of 1, 2, 3, 4, 5 and 6 cm. The following variables were evaluated: emergence percentage, first count and emergence speed index, seedling length and dry mass. The results showed that HL at a depth of 1 cm sowing produces higher vigor seedlings.
