Vermicompostagem enriquecida com remineralizadores de Kamafugito na cultura de brócolis (Brassica oleracea L.)

Abstract

The objective of this study was to evaluate different doses and composite compositions enriched with remineralizer in the development of broccoli. The experiment was conducted in a greenhouse at the Federal University of Goiás-Goiânia, with a randomized block design in a factorial arrangement with 5 doses, 3 types of compounds and 5 replicates. Compound doses: 0, 30, 60, 90 and 120 t ha-1. The compounds employed were: C1 - bovine corral cow herds + grass straw in the proportion of 1: 2 + kamafugito (6 t ha-1 from Kamafugito); C2 - Bovine cow herd + grass straw in a ratio of 1: 2 and C3 - Curdled cowpea. Plant height (AP) were evaluated; stem diameter; chlorophyll (Spad); total number of leaves in the plant (NF), dry mass production of the aerial part and content of potassium and organic matter. The C1 had satisfactory results than the others in the AP and in the NF, not differing from C2 in Spad. The production of broccoli responded markedly to the increase of the doses of organic compound.
