Produção de Mudas de Aroeira com Vermicomposto de Lodo de Curtume

The objective of this study was to verify the growth of seedlings of aroeira produced with vermicompost of tannery sludge destined to the recovery of degraded areas in the Cerrado. The experiment was conducted in a completely randomized design with four replicates, with four types of vermicompost (V1-25% L1 + 75% C2, V2-50% L1 + 50% C2, V325% L2 + 75% C2; And V4-50% L2 + 50% C2) and 3 application rates (D1-5g, D2-15g, and D3-30g). The height and diameter of the plants were collected at 30 and 60 days after sowing. The dose 1 of the three vermicompost (V1, V2, and V3) was better than the other doses for the 30 DAS. The best dose should be 5 g. In obtaining larger plants in the production of forest seedlings, smaller doses of vermicompost of tannery sludge may be used.
