Resumo: | Groundwater reserves in the semi-arid regions, which are mostly brackish, could be used to meet local water demands. Hydroponic cultivation is an alternative of rational use of water. Thus, the objective of this work was to evaluate the technical feasibility of using brackish groundwater in the semi-arid region of Bahia and Recôncavo of Bahia for hydroponic production of curly lettuce cv. ‘Verônica’ and purple lettuce cv. ‘Quatro Estações’. The experiment was conducted in a greenhouse in the city of Cruz das Almas, Bahia State, in a randomized block experimental design, composed of seven treatments [T1- public-supply water; T2- water from the well of UFRB; T3- reject water from the well of Cruz das Almas; T4- water from the well of Sapeaçu; T5- reject water from the well of Sapeaçu; T6- reject water from the well of Conceição do Coité and T7- artificially salinated water (NaCl)] and six replicates in an experimental hydroponic structure using the nutrient film technique (NFT). The following variables were analyzed: number of leaves, shoot fresh matter, shoot length, root length, shoot dry matter, and root dry matter. Relative shoot dry matter production in curly lettuce increased by 1, 5, and 2% in the treatments T2, T3, and T4, respectively, whereas in purple lettuce, the increments were 10, 1, and 20%, respectively, for the same treatments. The use of brackish groundwater from the deep tubular wells of the Federal University of Recôncavo da Bahia and Sapeaçu and desalination reject water from the tubular well of Cruz das Almas proved to be technically feasible for hydroponic lettuce production. |

O cultivo hidropônico é uma alternativa de exploração racional de água. Com isso, o objetivo do trabalho foi avaliar a viabilidade técnica da utilização de águas subterrâneas salobras do Semiárido e do Recôncavo Baiano na produção hidropônica de alface crespa cv. Verônica e alface lisa repolhuda roxa cv. Quatro Estações. O experimento foi conduzido em casa de vegetação, no Município de Cruz das Almas, Bahia, em delineamento experimental em blocos aleatorizados, composto sete tratamentos [T1 - água de abastecimento; T2 - água do poço da UFRB; T3 - rejeito do poço do Município de Cruz das Almas; T4 - água do poço do Município de Sapeaçu; T5 - rejeito do poço de Sapeaçu; T6- rejeito do poço do Município de Conceição do Coité e T7 - água salinizada artificialmente (NaCl)], com 6 repetições, em estrutura hidropônica experimental com a técnica do fluxo laminar de nutrientes (NFT). Foram analisadas as seguintes variáveis: número de folhas, massa de matéria fresca da parte aérea, comprimento da parte aérea, comprimento da raiz, massa de matéria seca da parte aérea e da raiz. A produção relativa da massa de matéria seca da parte aérea da alface crespa teve incremento nos tratamentos T2, T3 e T4 de 1, 5 e 2%, respectivamente. Na produção relativa da alface roxa ocorreu incremento de 10, 1 e 20%, respectivamente, para os mesmos tratamentos. A utilização de águas subterrâneas salobras exploradas dos poços tubulares profundos da UFRB, de Sapeaçu e o rejeito da dessalinização do poço de Cruz das Almas no Recôncavo Baiano, mostrou-se viável tecnicamente para produção de alface.UEL2018-05-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa científica ( Artigo original)application/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2881010.5433/1679-0359.2018v39n3p947Semina: Ciências Agrárias; Vol. 39 No. 3 (2018); 947-962Semina: Ciências Agrárias; v. 39 n. 3 (2018); 947-9621679-03591676-546Xreponame:Semina.
