Society becomes increasingly aware of the externalities presented by conventional agriculture, so the demand for less environmentally degrading systems is increasing. In this context, the objective was to characterize the agronomic performance of corn in soil fertilized with different organic fertilizers. The experimental design was in randomized blocks 5 treatments and 15 repetitions, totaling 75 experimental units. The treatments were: control (without fertilizer); cattle manure (40 t ha-1); poultry manure (5 t ha-1); goat (65 t ha-1) and mixed manure (cattle + poultry + goat) (36 t ha-1). At 14, 21, 28 and 35 days after planting (DAP), plant height, leaf number and stem diameter were measured; the height of the first ear in the stem at 80 dbh. The results demonstrate that for the evaluated characters, the lowest values ​​were observed in the treatment with cattle manure. Mixed fertilization increased the number of leaves. The goat manure promoted larger stem diameter and number of ear / plant. The weight of the ear / plant was increased with the use of goat and mixed manure.
