Maize (Zea mays L.) is one of the most important crops for biomass production as source for producing biogas. The water stress affects significantly the maize biomass production. However, there is a wide response of maize plant to drought according to the cultivated hybrid. That is why the maize hybrids behaviour to specific climatic and soil conditions has to be well known in view to be cultivated the right hybrid for producing biomass for energetic purposes.The aim of the paper was to present the results obtained at an assortment of maize hybrids regarding the above-ground biomass under the soil and climatic conditions from South Romania in the drought year 2012. Ten hybrids created in Romania were studied, respectively: CERA 270, CERA 290, CERA 370, CERA 390, CERA 6, CERA 420, CERA 2504,CERA 4505, Baragan 48, and CERA 10. The hybrids were studied in four different locations in South Romania,respectively: Fundulea – Calarasi County; Vâlcelele – Calarasi County; Visani – Braila County; Posta Câlnau – Buzau County.In the climatic conditions of 2012 in South Romania, five of the ten studied hybrids (CERA 2504, CERA 270, CERA 390, CERA 10, and CERA 420) registered values of the above-ground dry biomass production higher than 9 tons per hectare. Dry biomass production of stem and leaves that could present importance for different uses after harvesting ranged between 3.2 and 4.6 tons per hectare.
