This work had the objective to assess the effect of different systems of soil management on the components of corn and Brachiaria decumbens production in the conditions of the coastal plateau of the State of Alagoas. The experiment was carried out in the Center of Agrarian Sciences of the Federal University of Alagoas in the year of 2006, in a Yellow Latosol (Oxisols) Cohesive dystrophic soil. The treatments used were: usual preparation system (SPC); minimum cultivation (SCM); direct plantation (SPD) and farming-cattle integration (ILP), this one joined with B. decumbens. The hybrid of maize BRS 3003 was used whose variable had been: number of plants ha-1 (PP), length of spikes (CE), number of row grains on spikes-1 (NF), number of spike (NE), mass of 100 grains (M100) and grain yield (PG); and fresh weight (MN) and dry weight (MS) of the B. decumbens. The results showed that the soil management systems influenced the PP, NE and PG, but not the variables CE, NF and M100. The treatments ILP and the PD were the most promising management systems. In system ILP, the accumulation of MN and MS did not have influence in the production of corn grains, representing an interesting food source for farm animals.
