Abstract:
The aim of this study was to evaluate the vegetative growth and the production of irrigated 'Pérola' pineapple. The experimental design was in randomized blocks with four replications and sampling times at 1, 173, 248, 291, 354, 424, 488, 642, 703, 764, 858 days after planting. Evaluations were made of plant height, stem diameter, D-leaf length, fresh and dry matter of leaves, stem, root, fruit, crown and slips, vegetative biomass, total biomass, maximum accumulation rate, relative growth rate and crop growth rate. The results were submitted to analysis of variance and regression. The production of 'Pérola' pineapple fresh fruit is 66.41 t ha-1 and an average weight of 1.39 kg fruit-1. The 'Pérola' pineapple at the end of the cycle produces 134.34 and 61.90 t ha-1 of total and vegetative fresh matter, respectively.
