Among the species of greatest potential use of Caatinga is the Dimorphandra mollis, which can be harnesses from seeds, fruits, roots, bark, latex, oils and resins that have many uses for people, such as food, medicine, utensils, tools and crafts. Thus, the objective of this test was to evaluate the initial growth of D. mollisin relation to substrates. Therefore, we carried out a test in completely randomized design (CRD) with eight treatments (sand -A Solo -S, Dung goat -EC, Coconut Powder -PC, A + CE, A + PC, S + EC and S + PC), with four replicates of 18 seeds each. The test was conducted in Greenhouse of IFCE -CampusSobral,in Sobralcity–Ceará State, between February and April 2016. The seeds were treated with H2SO4to overcome dormancy in then germinated in polyethylene trays 162 cells, the eight substrates mentioned. At 60 days after sowing, held the final evaluation of the test, measuring-: plant height, leaf number, stem diameter, root length, Dickson quality index, dry weight of shoot and root. With the results it was observed that the use of mixtures with two substrates sand + goat manure, sand + coir dust, soil + goat manure and soil + coconut powder (1:1 -v/v) provides seedlingsof D. mollismore developed and with greater vigor.
