Compost and vermicompost extracts represent an alternative to synthetic fertilizers and pesticides because of their beneficial effects on plants. In this work, we composted as well as vermicomposted a mixture of press palm fiber, cofee pulp, and food waste. The mixture was then extracted and analyzed using 12 different extraction method combinations (aeration, substrate, and weight:volume ratio). Canonical discriminant analysis was carried out to evaluate the differences between the various treatments, microbiological parameters, and physicochemical factors, and allowed us to assess their influence on seed germination. Canonical discriminant analysis allowed us to find the optimal extraction method for enhanced seed germination, and also the factors that lead to an increase in macronutrients, namely composting, a compost:water ratio of 1:3, and the use of a non-aerated method.
