The use of organic compost in agriculture is a practice that brings many advantages, avoiding environmental contamination and nutrients  immobilization, besides being a source of 
organic matter in soil. Thus, this study addresses  the production of organic compost through the association of wastes in different intervals of tilling. These practices are undertaken to better understand the influence that these procedures, association of waste and different tilling intervals, have on the final product and its influence on the  cultivation of sorghum (Sorghum bicolor). The experiments were conducted on the Universidade Federal de Lavras? campus, one in field and another in greenhouse. Two different mixtures of residues for compost were made, only coffee husk and coffee husk associated with cattle manure, wich suffered four different tillage intervals and after obtained the compost they were tested in agricultural crop. Larger tilling intervals reduce nitrogen loss and decrease the need of labor. Organic composts obtained with shorter tilling intervals present a lower electrolytic conductivity. The addition of manure to the coffee husk provides a decrease in the C / N ratio. Composts from the mix of coffee husk and manure provide better results for fresh and 
dry biomass.
