The research aimed to evaluate the agronomic and yield traits of corn hybrids in two locations. The randomized blocks design arranged in an 11x2 factorial scheme (11 hybrids and two locations) with four replications was used. Each plot consisted of four rows of five meters. The evaluations took place in the two central rows leaving 0.50 m as a border at the ends. The variables analyzed were plant height, first ear insertion height, ear diameter, ear length, number of grain rows per ear, number of grains per row, 1000-grain weight, and grain yield. The corn hybrids adapted better in Santa Isabel. Regarding grain yield, in Santa Isabel, the hybrids were more adapted, and in Campinorte, the hybrid MG 711 PWU was the one that obtained the best performance. The MG 580 PWU hybrid presented the worst result in both locations.
