Zusammenfassung:Pitaya is still a culture lacking of research and information that support the definition/ adaptation of production systems adapted to Brazilian soils and climate, although in recent years there has been an increase in its agricultural expansion, as in Brazil as in other countries. Thus, the aim of this study was to evaluate the effect of mineral fertilization on the early growth of pitaya and then to obtain directed information to the definition of adequate fertilization managements of the culture. For this purpose, we tested five doses of nitrogen (N) (0, 150, 300, 450 and 600 mg [dm.sup.-3]) and potassium (K) (0, 75, 150, 225 and 300 mg [dm.sup.-3]), and the levels of each nutrient, arranged in a 5x5 factorial design with four blocks. For a significant interaction (p
