Fava danta (Dimorphandra mollis Benth. - Leguminosae-Caesalpinioideae) is a tree species found in Cerrado, useful in the recovery of degraded areas and as an ornamental plant. Rutin, extracted from the fruit, is a bioflavonoid used in the pharmaceutical industry which acts on the permeability and resistance of capillaries, representing an alternative income for farmers of the north of Minas Gerais.. This study aimed to determine the effects of soil type and fertilizers on the germination and vigor of fava-d'anta sown directly in the field. In addition aimed to assess the effect of fertilization and its interaction with the seasons of the year in the development of D. mollis in the field. We evaluated the following features: emergence, emergence first count, emergence speed index, survival rate, seedling height and diameter. There was no significant interaction among factors, soil type and fertilizers. The best results for emergence and ESI (emergence rate index) were obtained when the seeds were sown in local soil. The survival rate after one year of planting was 53.571% and the cattle manure and rock phosphate fertilization improved the development of bean-d'anta in the field. Thus, fertilization of fava-d'anta favors growth in height and diameter, but it does not influence the survival of plants grown by direct seeding.
