In the province of Chimborazo, found in the Riobamba canton, a study was done with the purpose of comparing different subtracts for the production of earthworm humus (pig feces, guinea pig feces, rabbit feces, bovine feces, market residues, and vegetable residues from the harvest) and its productive effect in vegetables (radish, onion, beet and cabbage). Twenty-four beds, 1.5 m2 (1.5 x 1) in size, as well as sixteen 3 m2 (1 x 3) parcels were used for the study. A design of complete blocks was applied with a monofactorial in the first test, and a bifactorial in the second test. The experiment lasted forty weeks. In general, the best productive behavior by the earthworm humus was distributed among various subtracts. The vegetable residues had the best final weight with a value of 66.75 Kg/parcel. The treatment with guinea pig feces had the best nitrogen content (0.29%). Bovine feces had the best phosphorus content (1.08%). Rabbit feces produced 10.6% of potassium as well as the highest number of earthworms in the harvest (6,900,00). With regards to the production of vegetables, cabbage responded well to almost all of the variables studied. Cabbage obtained superior values than the rest of the vegetables with a 99.5% capture and a 0.25% mortality. The other variables could not be compared because different types of vegetables were used. In the total economic analysis, it was seen that there was a expenditure of 851,960.00 sucres against an income, from the sale of humus and vegetables, of 1,065,000.00 sucres. The net income was 213,120.00 sucres and the benefit/cost was 1.21. It is recommended that this technique be used for small scale production, because the humus improves the ground's physical and chemical characteristics, thus obtaining representative economic gains.
