The aim of this work was to evaluate the influence of organic fertilizers on the agronomic, physicochemical and sensory characteristics of curly kale (Brassica oleracea L. var. acephala, Darkibor). The treatments were: A, Control = without fertilization; B = with organomineral fertilizer and C, D and E = with organic fertilizers. The plants were evaluated sixty days after planting in relation to agronomic, physicochemical and sensory parameters. The data were analyzed by ANOVA, considering the level of significance (p≤0.05) and, when necessary, the Tukey’s test was applied, and for the ranking test, the Friedman’s test was employed. The organic and organomineral fertilization had a positive influence on petiole length, width and total number of leaves, plant height and leaf area, when compared to the control (A). For stem diameter, leaf length and chlorophyll content, there was no significant difference among the treatments. Regarding the physicochemical analyses, there was no significant difference among the treatments. The treatments met the Brazilian legislation for the microbiological analysis of the leaves. The sensory analyses of ranking and acceptability showed no difference among the treatments. In general, the use of organic and organomineral fertilizers promoted greater efficiency for the kale plants with regard to the agronomic characteristics.
