Abstract
The pineapple (Ananas comosus L.), originally from South America, is the third most produced fruit in Brazil. The potassium nutrient plays a fundamental role on the fruit quality. The objective of this study was to evaluate the influence of potassium doses applied to the soil on fruit yield and on the physical and chemical characteristics of the Pérola pineapple cultivar. The design used randomized block design with four repetitions; the treatments consisted of five doses of K2O: 0; 222; 444; 666 and 888 kg ha−1 applied in the form of potassium chloride, divided into two applications, after floral induction. The evaluated variables were: fruit yield per hectare and pulp, fruit and crown fresh mass, fruit diameter, fruit and crown lengths, titratable acidity, soluble solids, vitamin C, juice pH and soluble solids/titratable acidity ratio. Potassic fertilization increased the yield of both fruit and pulp per hectare, the fruit and crown fresh mass, the diameter of the fruit, the lengths of the fruit and crown, titratable acidity, soluble solids, vitamin C and decreased the ratio of soluble solids to titratable acidity in the juice. The rise in potassium nutrition improves the quality and yield aspects of the pineapple ‘Pérola’ fruit.
