Morphological analysis of cabbage (Brassica oleracea L. var. acephala) grown in pots under different manure dosages

Abstract

Butter cabbage (Brassica oleracea var. acephala) is a vegetable originating from the Mediterranean coast and belongs to the Brassicaceae family. Its consumption in Brazil has increased due to its nutritional properties and different ways of using it in cooking, thus favoring its cultivation in the country. The objective was to analyze the morphological development of cabbage grown in pots in response to different doses of avian manure. The work was conducted from November 2019 to January 2020, in a greenhouse at the State University of Alagoas, Campus I, located in the municipality of Arapiraca-AL. The experiment was performed DIC (completely randomized design) was carried out using four treatments (T1 - soil without manure, T2 - soil + 50g of manure, T3 - soil + 75g of manure and T4 - soil + 100g of manure) and 5 repetitions. Morphological monitoring was carried out in 12 weeks, initially observing the following variables (pre-harvest): plant height, stem diameter and number of leaves; then, in the post-harvest, the following were evaluated: root length, root fresh mass, plant fresh mass, root dry mass and plant dry mass. All analyzed variables were submitted to analysis of variance, and for comparison of means, the Tukey test was used (p<0.05). With the results obtained, it was verified that there were no significant differences between the treatments in response to the manure dosages.
