Abstract
The waste destination is a concern to industries and, one of the solutions are fertilizers. Therefore, the objective of this study was to evaluate the efficiency liquid tannery sludge has as an alternative of foliar fertilization in Conilon coffee seedlings. The experiment was carried out in a randomized block design with six treatments and eight replications, for 228 days. The control treatment was pure water, and five doses of tannery sludge were applied monthly (6.20, 8.80, 11.47, 14.10, and 17.60 mL of sludge diluted in one liter of water). The biometric and gravimetric growth characteristics were evaluated. Also, the quality index of the seedlings was assessed, and it was observed that fertilization using tannery sludge diluted above 14.23 mL.L-1 began to cause toxic effects on Conilon coffee seedlings. The doses between 8.80 and 14.23 mL.L-1showed potential usefulness for the seedlings production.
