This research aimed to assess the emergence and initial growth of Copaifera pubiflora Benth. (copaibeira) exposed to vegetable land produced in school composting. The seeds of C. pubiflora were collected in the area of the riparian forest of Boa Vista, Roraima and classified as size (small or large) and performed the biometric characterization (length, diameter and mass of the seed). The experiment consisted of six different doses of vegetable land (0, 20, 40, 60, 80 and 100%) in sterile sand. The variables evaluated responses were: emergency percentage of seedlings, height of the aerial part, diameter of the stem and dry matter of seedlings. There was significant difference in the quality of seedlings of C. pubiflora cultivated according to the size of seeds and doses of vegetable land. Plants originating from large seeds have better quality in the measured variables. The use of vegetable land in doses greater than 20 and 40% interferes negatively in the emergence of small and large seeds of C. pubiflora, respectively. The initial growth of plants from C. pubiflora is benefited when using doses of up to 60% of vegetable land and 40% of sterile sand, for both seed sizes.
