Resumo: In hydroponic culture is common to evaluate the concentration of nutrient solution through electrical conductivity (EC). The aim of this work was to evaluate the best electrical conductivity of nutrient solution to lettuce crop, cv. Verônica. Four treatments were studied in differents electrical conductivity of nutrient solution. The Hoagland & Arnon (1950) nutrient solution was used as pattern, which to make several dilution until to get ideal quantities of each nutrient to reach the differents electrical conductivity: 1,0; 1,5; 2,0; 3,0 mS cm-1. The statistic design were blocks, with four treatments and six replications. In the treatment EC = 1,0 mS cm-1 was obtained good yield, with apropriate concentration of N, P, K, Ca, Mg and S and low level of nitrate, lower than the maximum allowed by the Comission of the European Communities.

Este trabalho teve como objetivo determinar a melhor condutividade elétrica da solução nutritiva para o cultivo de alface tipo crespa cultivar Verônica. Testaram-se 4 tratamentos que consistiram em diferentes condutividades elétricas da solução nutritiva. A solução nutritiva de Hoagland & Arnon (1950) foi utilizada como padrão, da qual realizou-se várias diluições até a obtenção de quantidades ideais de cada nutriente para atingir as diferentes condutividades elétricas: 1,0; 1,5; 2,0; e 3,0 mS cm-1. O delineamento estatístico utilizado foi blocos, com quatro tratamentos e seis repetições. A partir dos resultados obtidos pôde-se concluir que o tratamento CE = 1,0 mS cm-1 proporcionou boa produção, com concentrações adequadas de N, P, K, Ca, Mg, S e baixo teor de nitrato, estando abaixo do limite máximo de nitrato permitido para alface, na Europa.UEL2009-04-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/209010.5433/1679-0359.2002v23n2p157Semina: Ciências Agrárias; Vol. 23 No. 2 (2002); 157-164Semina: Ciências Agrárias; v. 23 n. 2 (2002); 157-1641679-03591676-546Xreponame:Semina.
