The experiment was conducted over three years: 2009, 2010 and 2011, in five locations: Fundulea, Calaraúi county; Valu lui Traian, Constanta county; Sarichioi, Tulcea county; Cazasu, Braila county and Caracal, Olt county. These locations were selected as being representative for corn cropping area from South Romania. Eight corn hybrids (F475M, Olt, Paltin, F376 from Fundulea Institute and PR35F38, PR37Y12 , PR36V74, PR37F73 from Pioneer) were tested using two levels of water regime: irrigated with 800 3/ha and non-irrigated. The study showed that the 2009 was less favorable for corn crop in all testing areas, comparing with 2010 and 2011 which were favorable for corn crop. In the case of non-irrigated corn trials the yield was influenced by the climatic conditions of the year, while in the case of irrigated corn trials, the yield was much higher and stable. The hybrid PR36V74 had the highest yield in all irrigated and non irrigated testing locations. Average yield of the hybrids over three years varied between 93.8 q/ha (F475M) and 130,3 q/ha (PR36V74) in non-irrigated conditions, while in irrigated conditions average yield increased significantly by applying of 800 m3/ha varying between 101.2 q/ha (F475M) and 155,9 q/ha (PR36V74).
