Vermicomposting is the process of transforming the little degraded organic material into organic matter stabilized through the action of the earthworms and the microsymbionts. This study aimed to evaluate the effect of the addition of increasing doses of vermicompost enriched with rock dust (MB4®) on soil chemical characteristics and on radish (Raphanus sativus) production.The vermicompost was prepared by incubating the mixture of cattle manure, rock dust and earthworms for 55 days. After this period the vermicompost treatments corresponding to 0; 5; 10; 15; 20 and 25 t ha-1 were incubated in the soil for 60 days. At the end of incubation, soil samples from each experimental unit were chemically analyzed.Two radish plants were harvested 30 days after sowing (after soil incubation) to be evaluated for fresh and dry shoot biomass, fresh root weight (radishes), radish longitudinal and transverse diameters and root / shoot ratio. It was found that all soil chemical characteristics were significantly influenced and varied quadratically as a function of increasing doses of vermicompost applied to the soil. The use of increasing doses of vermicompost enriched with rock dust improved soil fertility conditions providing higher yield efficiency of radish fruits. The application of vermicompost enriched with rock dust results in well developed plants favoring the production components. The average yield of radish fruits was 14.52g / plant.
