Publicação on-line; 38 ref.; 2 tables; 5 illus.; Summary (En) ABSTRACT Annona crassiflora Mart. presents medicinal and food potential, and is also used in the recovery of degraded areas, however, little is known about its nutritional requirements. The aim of this work was to analyze the initial growth of A. crassiflora submitted to nitrogen and potassium fertilization. The experiment was conducted with a complete randomized block design with four replicates, each consisting of five nitrogen and potassium doses (0, 50, 100, 150 and 200 mg dm-3). Results were submitted to regression analysis. The species showed significant response for nitrogen fertilization regarding biometric variables, biomass, DQI and nutritional contents at doses of 100 to 200 mg dm-3. On the other hand, potassium only influenced DQI, nutritional content and accumulation of A. crassiflora seedlings. Keywords: seedlings, nitrogen doses, potassium doses.
