Organic waste generated in the markets of a community in Ecuador, was subjected to four biological treatments: composting (T1): a pile of 1050 kg of waste; co-composting (T2): a pile of 900 kg of waste and 150 kg of straw; takakura (T3): a pile of 300 kg of waste and 50 kg of seed compost and vermicomposting (T4): 1 m2 bed with 60 kg of pre-composted waste. The market waste was mechanically shredded. The piles were placed in a semi-enclosed. In the organic fertilizers obtained, the pH (T1=9.8; T2= 9.9; T3= 7.84 and T4= 8.01), electrical conductivity in dSm-1 (T1= 4.43; T2= 4.57; T3= 2.19 and T4= 0.56), percentage of organic matter (T1= 31.69; T2= 31.45; T3= 26.15 and T4= 25.32), percentage of macronutrients: nitrogen (T1= 0.81; T2=2.33; T3= 1.04 and T4= 2.34), phosphorus (T1= 0.80; T2= 1.86; T3= 0.97 and T4= 2.00) and potassium (T1= 0.48; T2= 4.22; T3= 1.38 and T4= 3.76) and percentage of germination index (T1= 64.59; T2= 91.3; T3= 95.57 and T4= 100) were determined. The ANOVA statistical tool and the Tukey-b test were used (P < 0.05). The results indicated that vermicomposting was the best treatment.
