This study aimed to evaluate the effect of lime and biofertilizer Supermagro on quality and yeld of pineapple ‘Perola’. The treatments were three rates (0, 50 and 100% of the recommended for pH 5.5) of dolomitic lime and three concentrations of biofertilizer (0, 5 and 10%). The results showed that the use of lime did not affect fruit size without crown, fruit mass with and with out crown, total soluble solids, pH, titratable acidity, total soluble solid and titratable acidity ratio of the pulp, and yeld, but fruit size with crown diameters of the fruit and the contents N, P, Zn, Mn and Mg present in the leaf. The use of biofertilizer affected only the Zn present in the leaves. On the other hand, contrasts indicated that intermediate doses of lime and fertilizer, showed a trend of increase of average in most variables, especially in yeld. Present in leaf N presented a positive and significant correlation with fruit size with and without crown, fruit mass with crown, total soluble solids and titratable acidity of the pulp, and productivity, and Ca, with basal and medial fruit diameter.
