A compostagem da casca de café carbonizada favorece a produção de mudas de ingá

Abstract

The aim of this study was to evaluate the carbonized and decomposed coffee husk in the seedling production of Inga vera Willd subsp. affinis (DC). T. D. Penn by assessing the survival and growth. The experiment was conducted in recipient of 110 cm³, being installed in a completely randomized design consisting of seven treatments with five replications of eight seedlings per plot. After 180 days, the survival rate, plant height, stem diameter, ratio between plant height and stem diameter, shoot dry mass, dry mass of root system, total dry mass, dry mass ratio of shoot/root dry mass and Dickson Quality Index (IQD) were evaluated. The composting of the carbonized coffee husk improved the quality of Inga vera subsp. affinis seedlings; and the substrate with proportions of this component resulted in the best responses for survival and most of the quality parameters evaluated. Further studies are recommended to better understand the effects of this component for the seedling production.
