Residue of charcoal added to earthworm humus for the production of young female fingerlings

Abstract

The use of industrial waste in agriculture helps to reduce environmental impacts, a result of
their acumulation, in the yards. The objective of this study was to evaluate the effect of doses
of charcoal residues on earthworm humus for the production of pepper seedlings (Capsicum
baccatum). Húmus was obtained from the EMBRAPA standard guild minaret humus. The experimental
design, was a randomized blocks, with 4 coal concentrations: 0%, 2.5%, 7.5% and;
15%, with 4 replicates and 25 plants each. The following variables were evaluated: leaflet diameter,
leaf number, plant height, root length, shoot and root dry weight. The addition of 2.5%
of residue promoted better biometric results; Doses of approximately 9% and 8%, promoted
a higher increase of aerial and root dry matter, respectively. The addition of coal residues in
the production of young girls’ pepper seedlings can reduce production costs, as well as better
allocation of this residue.
