The researches have been done in the very favourable region for maize cultivation from Arad County. The paper contains the yields obtained during the period 2003-2006 in Sagu Arad for 16 maize hybrids with different vegetation period and the yields obtained in the region Utvinis from the same County, for 21 maize hybrids. The high percentage of hybrids belonging to the Pioneer brand has determined us to use the hybrids of this class. The grain yields were of between 4616 kg/ha and 72,89 kg/ha in Sagu and of between 7553 kg/ha and 10592 kg/ha in the region Udvinis.
