Nutrient contents and production of rocket as affected by nitrogen concentrations in the nutritive solution Scientia Agricola
Cavarianni,Rodrigo Luiz; Cecílio Filho,Arthur Bernardes; Cazetta,Jairo Osvaldo; May,André; Corradi,Mariana Marotti.
Empiricism in the use of nutrient solutions is frequent. Several times the same nutrient solution is used to grow different species based only on morphological similarities. This practice may lead to nutritional imbalances, affecting not only the production but also the quality of the product due to an accumulation of nitrate. An experiment under hydroponic conditions - the NFT system - was conducted with the aim of evaluating the effect of the concentration of nitrogen in the nutrient solution on the production and on the nutrient and nitrate contents of rocket (Eruca sativa) salad leaves. The experiment was carried out in spring 2003, in a randomized block design and in a 4 x 3 factorial design, with four replicates. Four nitrogen concentrations in the...
