Abstract Papaya plants, Carica papaya L. cv. Solo, were treated with 3 levels of lime combined with 3 levels of P in a split-plot arrangement. Optimal yield of papaya was maintained when the pH of the surface soil ranged from 5.5 to 6.7. Liming lowered petiole concentrations of Mn, K, and Mg and raised those of Ca and P; petiole P was raised when P was applied only. Phosphorus fertilization increased the growth rate of the tree-trunk circumference only at the early stage of growth, while liming affected growth later than P. Phosphorus fertilization raised the petiole concentrations of P, N, Mn, and Zn and lowered petiole concentrations of K and Cu.
