The objective of this work was to evaluate the influence of the use of nitrogen and phosphorus in the culture of jambu. The experiment was initiated at the experimental farm of the agency APTA Polo Vale do Ribeira, using the Nazaré cultivar. The experimental design was complete randomized with fourlevelsof nitrogen (0, 37.5, 75 and 112.5 kg ha-1 N) and phosphorus (0, 75, 150 and 300 Kg ha-1P2O5),and four reapplications. After soil preparation, liming and fertilization, seedlings of jambu were transplanted at a spacing of 0.50 x 0.5 m. The experimental plot was 1.0 x 1.0 m. Fresh and dry mass of leaves and flowers and number of flowers were analyzed. The production of fresh and dry leaves and flowers were influenced by fertilization. Thelevelsof nitrogen affected the outcome, as theyprovided a linear increase in all variables, and the phosphorus level of 75 kgha-1 P2O5 caused the highest average production in the number of flowers and in the fresh and dried mass of flowers.
