Resumo: | In aquaponic systems, the residual water from the cultivation of fish is not enough to meet the nutritional demands of plants. The main objective of this study was to investigate how to adjust a nutritive solution for the cultivation of lettuce (Lactuca sativa L.) in aquaponics, based on hydroponics. The treatments included six separate crops of lettuce in an aquaponic system, while the hydroponic system served as the control. In each treatment, three blocks were used to quantify the parameters of ‘head’ diameter, number and dry weight of leaves, shoot dry weight, root dry weight, total dry weight, and the concentration and accumulation of nutrients in the total dry weight of the lettuce plants. The lower nutrient supply led to the occurrence of the lowest total dry weight in the C2 leaf crops when compared to that of the other crops of aquaponics, which had adequate time for system maturation. The system maturation and the use of a balanced solution in the C5 and C6 crops allowed the head diameter of the aquaponics plants to be equal to those of the hydroponics plants. In the aquaponic system, N and Fe were the most limiting macronutrient and micronutrient, respectively. To produce lettuce in an aquaponic system, it is necessary to ‘ripen’ the crop water for at least 30 days, and supplement micronutrients in the form of mineral fertiliser. |

O objetivo principal deste estudo foi investigar como ajustar uma solução nutritiva para o cultivo de alface (Lactuca sativa L.) em aquaponia, tendo como base à hidroponia. Os tratamentos foram seis culturas distintas de alface em sistemas de aquoponia e tendo como controle o sistema de hidroponia. Foram utilizados três blocos em cada tratamento para quantificar os parâmetros: diâmetro da “cabeça”, número de folhas e massa seca das folhas, massa seca da parte aérea, massa seca da raiz e massa seca total e a concentração e acúmulo de nutrientes na massa seca total de plantas de alface. O menor aporte de nutrientes, fez com que o peso seco total das folhas do cultivo C2 fossem menor quando comparadas às demais safras da aquaponia, que possuíam um adequado tempo de maturação do sistema. A maturação do sistema e o uso da solução balanceada nos cultivos C5 e C6 permitiram que o diâmetro da cabeça das plantas da aquaponia fosse igual ao da hidroponia. No sistema de aquaponia, o N foi o macronutriente mais exigido e o Fe dentre os micronutrientes. Para a produção de alface em sistema aquopônico, é necessário a maturação da água das culturas no mínimo 30 dias, juntamente com a suplementação de micronutrientes na forma de fertilizante mineral.Universidade Federal Rural do Semi-Árido2022-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1077610.1590/1983-21252023v36n103rcREVISTA CAATINGA; Vol. 36 No. 1 (2023); 21-32Revista Caatinga; v. 36 n. 1 (2023); 21-321983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/10776/11067Copyright (c) 2022 Revista Caatingainfo:eu-repo/semantics/openAccessDuarte, EglersonSilva, Enilson de BarrosMoreira, Fernanda da ConceiçãoBraga, Demerval Santos, Shara Gomes dos2023-07-27T12:11:43Zoai:ojs.periodicos.ufersa.edu.br:article/10776Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:58.590125Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
