Resumo: The nutritional diagnosis is fundamental for determining plant nutrients, in order to correctly manage the nutritional requirements for each species. Thus, in order to determine the ideal nutrient amount and concentration for obtaining the best yield and quality of lisianthus grown hydroponically, an experiment was conducted in which the plants were grown under the NFT system in different nutrient solutions. The experiment was conducted according to a random block design arrangement in a 4x3 factorial scheme, totaling 12 treatments with three repetitions. The treatments were comprised of four cultivars (Echo Champagne, Mariachi Pure White, Balboa Yellow and Ávila Blue Rim) and three nutrient solutions (Test, modified Steiner and Barbosa). In the leaves, nutrient concentration and content were evaluated; in the aerial parts of the plants, only the content was evaluated. The plants grown in Barbosa solution and in the Test solution had satisfactory results regarding nutrient concentration and amounts, while the modified Steiner solution produced plants with limited nutritional qualities.
