With the aim to evaluate chili pepper production, cultivar 'Ancho', with no chemical fertilizers; the effect of five different vermicompost - perlite mixes were used, under greenhouse conditions. Rates of the organic material were: 0.0, 15, 30, 45 and 60% (v:v). A single plant was grown in a 20-L pot, with drip irrigation and using water only: except for the control treatment irrigated with Steiner nutritive solution. For crop management, organic agriculture authorized products were used only, using a complete random blocks design with four replications. The evaluated variables were: plant height (PH), leaf number (LN), flower number (FN), fruit number (FrN), fruit weight (FW), fruit diameter (FD), fruit length (FL), leaf dry weight (LDW), root dry weight (RDW), limb dry weight (LiDW). Values of the evaluated variables increased when vermicompost rates applied were increased also. Variables showing statistical differences among treatments were: LN and PH, during plant vegetative stage; FN and FrN, during productive stage; FD, FL and FW, during ripening stage. FW was the highest for treatment with 60% of vermicompost but was, statistically, only different to treatments with 30% or less than that. Treatment with 15% showed less FW. On the other hand, treatment with 60% of vermicompost, a single plant yield 1345 g, being 2.77-folds higher than 15% treatment.
