Conteúdo: | Emphasis on studies that seek sustainable energy alternatives to oil has increased over the last few years. Ethanol derived from sugarcane remains a promising technology for biofuel production. Waste from pineapple culture remains is a potential alternative raw material for biofuel production. The goal of this study was to determine the potential of residual biomass production of a pineapple crop, subjected to fertilization by different levels of nitrogen and potassium. The experiment was conducted in Northwest Paraná, in a commercial area in Santa Isabel do Ivaí-PR. The climate in this area is subtropical humid according to the Köppen classification, and has a sandy dystrophic red acrisol.The experimental design was a 4 × 4 factorial, where factor A: N doses (0; 11; 22; and 33 g per plant) and factor B: K2O doses (0; 11; 22; and 33 g per plant. The production of residual pineapple biomass responded differently to the N and K doses applied. Potassium fertilization had a positive linear correlation, up to the addition of 33 g plant-1 with a production of 5.88 Mg ha-1 .A dose of 18.138 g plant-1 yielded in the maximum dry biomass production for nitrogen fertilization.
