Resumo: | The deficiency of iron in the human organism causes the anemia, which is a public health problem. Food biofortification is a scientific tendency to avoid the disease. The objective of this study was to evaluate biofortification with iron of lettuce and arugula in soilless culture. Two experiments in hydroponics one for each culture were installed. The experimental design was in randomized blocks with five treatments and six replications. The treatments consisted in increasing concentrations of iron 45 (control), 90; 135; 180; 225 μmol.L-1. At 27 and 30 days after transplanting to arugula and lettuce, respectively, were evaluated: shoot fresh matter, number of leaves, leaf area, root fresh matter, root volume, shoot dry matter and root dry matter. The data were submitted to variance and regression analysis. The production of shoot fresh matter of lettuce and arugula decreased significantly with increasing iron concentration. Lettuce occurred reduction of 83.60% in the concentration of 180 μmol.L-1 Fe and arugula was a reduction of 67.86% in the concentration of 225 μmol.L-1 Fe. For lettuce production Vitoria Santo Antão and Rococo arugula hydroponically recommended the use of concentration of 45 μmol.L-1 Fe. |

Biofortification with iron of lettuce and arugula in soilless cultureDesempenho da alface e da rúcula em diferentes concentrações de ferro na solução nutritivaThe deficiency of iron in the human organism causes the anemia, which is a public health problem. Food biofortification is a scientific tendency to avoid the disease. The objective of this study was to evaluate biofortification with iron of lettuce and arugula in soilless culture. Two experiments in hydroponics one for each culture were installed. The experimental design was in randomized blocks with five treatments and six replications. The treatments consisted in increasing concentrations of iron 45 (control), 90; 135; 180; 225 μmol.L-1. At 27 and 30 days after transplanting to arugula and lettuce, respectively, were evaluated: shoot fresh matter, number of leaves, leaf area, root fresh matter, root volume, shoot dry matter and root dry matter. The data were submitted to variance and regression analysis. The production of shoot fresh matter of lettuce and arugula decreased significantly with increasing iron concentration. Lettuce occurred reduction of 83.60% in the concentration of 180 μmol.L-1 Fe and arugula was a reduction of 67.86% in the concentration of 225 μmol.L-1 Fe.

O ferro é um micronutriente importante para a alimentação humana principalmente na prevenção de anemia. Assim, objetivou-se com este trabalho avaliar o desempenho da alface e da rúcula com doses crescentes de ferro na solução nutritiva. Foram instalados dois experimentos em hidroponia, um para cada cultura. O delineamento experimental utilizado foi em blocos ao acaso, com cinco tratamentos e seis repetições. Os tratamentos foram representados por concentrações crescentes de Fe: 45 (controle), 90; 135; 180; 225 μmol.L-1. Aos 27 e 30 dias após o transplantio para rúcula “Rococó” e alface “Vitória de Santo Antão”, respectivamente, foram avaliadas: matéria fresca da parte aérea, número de folhas, área foliar, matéria fresca da raiz, volume da raiz, matéria seca da parte aérea, matéria seca da raiz. Os dados foram submetidos à análise de variância e de regressão. A produção de matéria fresca da parte aérea da alface e da rúcula diminuiu consideravelmente com o aumento da concentração de ferro na solução. Para a alface, a redução foi de 83,60% na concentração de 180 μmol.L-1 de Fe, e para a rúcula foi de 67,86%, na concentração de 225 μmol.L-1 de Fe. Considerando que as demais variáveis biométricas também reduziram seus valores com o aumento da concentração de Fe na solução nutritiva, recomenda-se o uso da concentração de 45 μmol.L-1 de Fe para o cultivo da alface “Vitoria de Santo Antão” e da rúcula “Rococó” em sistema hidropônico.Universidade Federal Rural da Amazônia/UFRA2017-07-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/2466Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 60 No 1 (2017): RCA; 45-52Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 60 n. 1 (2017): RCA; 45-522177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
