According to the theory of vegetative reduction, roots of epiphytic and atmospheric bromeliads, function only for plant fixation and sustentation to the phorophyte, while the leaves would exert the function of absorption and assimilation of water and nutrients. Nitrogen fertilization in bromeliads differs according to species and contribute to productivity, improving plant quality and reducing production costs. Epiphytic bromeliads are able to absorb organic and inorganic sources of nitrogen, with preference for the organic source due to the deposition of organic matter in the tank. The study aimed to evaluate the growth and development of bromeliad <em>Aechmea fasciata<\/em>, submitted to 0, 15 or 30 mM N from different nitrogen sources (urea or ammonium nitrate) applied into the tank or on root system (substrate). Commercially cultivated <em>A. fasciata<\/em> plants were grown and twice weekly fertilized with 10 mL of modified Hoagland &amp; Arnon n.1 (1950) nutrient solution. The experiment was conducted for 10 months, subsequently the biometric, biomass and physiological analyzes were performed. The results showed a tendency of plants growth with the increase of the nitrogen concentrations in the nutrient solution. There was no difference between nitrogen fertilization into the tank or on root system, corroborating with studies that attest the functionality of epiphyte bromeliads\u2019 root system. Tank fertilization with ammonium nitrate and urea at the 30 mM N dose had the highest F<sub>v<\/sub>\/F<sub>m<\/sub> ratios. The values \u200b\u200bof the agronomic (EA) and nitrogen utilization (EUN) indexes values \u200b\u200bin the different nutrient assimilation organs showed that the tank is more efficient than the roots and according to the source of nitrogen applied the ammonium nitrate presented higher EA. Our results showed that <em>A. fasciata<\/em> epiphytic bromeliad root system is functional for nitrogen uptake, being as efficient as the tank for nitrogen uptake and assimilation. Nitrogen organic source (urea) is a preferential source to root system and inorganic to tank.<br \/>\nKeywords: Bromeliad, Nitrogen Nutrition, Absorption, Root System<\/p>\n<p style=\"text-align: center\"><strong>RESUMO<\/strong><\/p>\n<p style=\"text-align: justify\">Brom\u00e9lias de h\u00e1bito ep\u00edfito est\u00e3o submetidas a descont\u00ednuos per\u00edodos de disponibilidade h\u00eddrica e nutricional; portanto precisaram desenvolver adapta\u00e7\u00f5es para sobreviver nestas condi\u00e7\u00f5es ambientais.

Plantas da variedade comercial <em>A. fasciata, <\/em>derivadas de sementes com aproximadamente seis meses de idade foram cultivadas e adubadas por duas vezes semanalmente com 10 mL de solu\u00e7\u00e3o nutritiva de Hoagland &amp; Arnon n.1 (1950) modificada.
