The objective of the present experiment was evaluate the effect inter cropping systems with the culture of the maize on the production components, aiming at to maximize the grain production and to increase availability of pastures for animal feeding. The treatments had consisted of the culture of DKB-950 maize (Hybrid Simple Modified), on three grassy species of (Brachiaria decumbens, Brachiaria brizantha and Panicum maximum cv. Tanzania) inter cropping systems and conventional tillege of soil. In foundation one applied 0, 35, 50 and 4 kg ha-1 of N, P, K and Zn respectively in the sulphate form of ammonium, simple superphosphate, potassium sulphate and zinc Sulphate. In covering it applied if 120 kg ha-1 of N. the used espaçamento was of 0,80 x 0,20 m, The experiment was arranged in a randomized complete block design, with four repetitions. The components of the production of the maize had not been affected by the studied systems of inter cropping, except for the number of spikes and production of grains, where the maize cultivated inter cropping systems with Brachiaria decumbens (4.787 kg ha-1) was better that the Tanzania (3.683 kg ha-1). The accumulation of dry mater presented significant difference between the treatments, in the which Tanzânia presented greater accumulates of dry mater.
