The use of residues for the production of papaya seedlings can point out an accessible solution to the producing areas. Therefore, the objective was to evaluate the influence of portions of 0 to 60% of tannery sludge in a mixture with commercial substrate, traditionally used in papaya propagation, being evaluated the emergence, biometric, gravimetric and quality characteristics of papaya seedlings. cv. Golden THB. The emergence characteristics had a similar performance between the proposed and commercial substrates. Overall, there were significant differences between treatments with more than 15% tannery sludge and the commercial substrate. Except for the percentage of emergence, significant results were found for regression, with the answer being the indication that gradually with the increase in the portion of the tannery sludge to the commercial substrate, there was a reduction in the characteristics analyzed. Possibly the effects of high salinity provided this response pattern, in addition to the nutritional imbalances as a result. Despite the good results of the emergence characteristics, in general, the mixture of tannery sludge to the commercial substrate limited the development and quality of papaya seedlings cv. Golden THB, for use only in proportions up to 15% of sludge.
