In this context, the objective of this study was to evaluate its use for the production of ornamental sunflower cv. Anão de Jardim in a bench-type low-cost hydroponic system, inferring on its technical feasibility and observing the possible impacts on the crop. The experiment was carried out in a greenhouse, adopting a completely randomized design with four treatments (T1 - nutrient solution of Furlani 100%, prepared in municipal supply water - control), T2, T3 and T4 - nutrient solution of Furlani, respectively, with 100, 75 and 50% strength, prepared in treated domestic effluent and six replicates, totalizing 24 experimental units, each consisting of 15 plants. All treatments met the nutritional requirements of the plants and had adequate contents of N, P, K, Ca and Mg in leaf and stem at harvest, leading to satisfactory plant growth, and produced acceptable commercial grade capitula and stems. The plants under treatment T4, despite producing capitula of commercial quality, exhibited great variability in comparison to the other treatments, therefore except this treatment any other treatment can be used for hydroponic production of ornamental sunflower utilizing treated domestic effluents. 2020 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49663642014 https://www.redalyc.org/journal/496/49663642014/ https://www.redalyc.org/journal/496/49663642014/html/ https://www.redalyc.org/journal/496/49663642014/49663642014.epub https://www.redalyc.org/journal/496/49663642014/movil 10.15446/dyna.v87n212.80839 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.212 Vol.87 |
