| Sumario: | Brassica oleracea L. var. acephala is an ornamental cabbage cultivated as foliage
for cutting due to the coloration of the rosette formed by its apical leaves. The plant
height and the diameter of the rosettes may be modified through the planting density;
however, there is not enough information about this. The aim of this study was to assess
the influence of the planting density of four cultivars of B. oleracea L. var. acephala of
the series F1 Crane: Bicolor, Pink, Red and Rose, on the plant height, rosette diameter,
number of leaves, leaf area, root volume, and aerial and root fresh and dry weight. The
experimental design was completely randomized, with six repetitions. The combination
of density (56 plants.m-2 and 28 plants.m-2) and cultivar allowed obtaining eight treatments.
The results showed that the treatments with high planting density improved
commercial quality indices: achieving greater stem height and more compact and
smaller diameter rosettes, leading to lower values of the rest of the vegetative variables
evaluated. Also, as productive alternative, it would allow a more efficient use of the soil
and reduce crop management activities such as manual leaves removal.
