COELHO, Ruimário Inácio et al. Nutritional status and growth caracteristics of pineapple in dystrophic yellow latosol 'Jupi' cultivated in fucntion of NPK fertilization. Ciênc. agrotec. [online]. 2007, vol.31, n.6, pp.1696-1971. ISSN 1413-7054.  https://doi.org/10.1590/S1413-70542007000600014.

The aim of this work was to evaluate the effects of NPK on the growth of leaves and fruits and nutritional status of pineapple. Slips of pineapple'Jupi', with weight of 250 g were planted in vessel with13 dm3 of dystrophic Yellow Latosol. The treatment consisted of 00; 31; 62; 93 e 124 g of NPK (20:05:20) divided in three applications (20%, 40% and 40%) of the dose after 45, 120 and 240 days. The experiment was carried out in a randomized block outline, with four replications. The mean weight of the fruit was influenced by NPK doses. The highest fruit weight was obtained in the fruit without crown and fertilization of NPK with 93 g. With the increase of doses of NPK, the brix tenors and total titled acidity increased while the relation brix/titled acidity decreased.
