POTENCIAL DE LODO DE CURTUME E MOINHA DE CAFÉ EM SUBSTRATOS PARA PRODUÇÃO DE PIMENTA CAMBUCI

Abstract

The objective of this study was to evaluate fruit production and the development and quality of cambuci pepper seedlings produced in a substrate formulated by mixing dehydrated tannery sludge with composted coffee moinha. The proportions (v/v) of 5, 10, 15, 20, 50 and 100% of tannery sludge mixed with coffee moinha were tested, compared with the commercial substrate Provaso^®. The experiment was implemented in two stages, in a greenhouse, using a randomized block design. In the first stage, 480 seedlings were produced in the treatments and the emergence, biometric, physiological and quality characteristics of the seedlings were evaluated. In the second stage, 96 of these seedlings were planted in the soil and their survival and fruit production were evaluated. Scott-Knott and Dunnett tests (p < 0.05) were applied, in addition to correlation analysis comparing the steps. The proportions of tannery sludge/coffee moinha of 10/90%, 15/85% and 20/80% presented the highest values ​​of development and seedling quality. The correlation analysis between the steps did not show significant results. The substrate with 20% of tannery sludge showed the highest averages in the second stage.
