| Popis: | Abstract The aim of this study was to evaluate root development and productivity of ‘Pérola’ pineapple as a function of split N and K fertilization and fertigation management. Four different split nitrogen and potassium fertilizations were evaluated in combination, as well as four different fertigation managements. Root samples were analyzed using the Safira software and surface area, length, root volume per soil volume, root diameter, dry mass, specific surface and specific length were quantified. Average fruit mass and average productivity were also quantified. The different split fertilizations and fertigation management alternatives caused changes in the root system of ‘Pérola’ pineapple. Regarding dry root mass per cm3 of soil, irrigated and fertigated plants split in twenty-seven N applications and four K applications, was 0.106 g.cm3, while irrigated and fertigated plants split in fifty-four N applications and four K applications was 0.523 g.cm3. Regarding productivity and average fruit mass, monthly applications and in four K applications until the ninth month of plant age promote greater increments, while split nitrogen fertilization showed no influence. |
