The experiment was conducted in completely randomized designwith four replications and treatments applications started in the fifth month after planting. Treatments were fourdoses of K20(160, 320, 480 and 640kg K2O ha-1) that correspond to 50, 100, 150 and 200% of recommended dose based on soil analysis. Potassium was supplied in the form of KNO3, in the irrigation water, associated to the others fertilizers. During the five monthharvest period, the papaya yield reached 22.3 t ha-1, fruit number was 67,776 fruit ha-1, fruit weight was about 418.6 g and soluble solid titratable acidity ratio as high as 13.9.  aPapayas  aPlant nutrition  aPotassium nitrate  aMamão  aNitrato de Potássio  aNutrição Vegetal1 aLIMA JUNIOR, J.
