The average number of leaves per plant at the studied maize hybrids ranged from 9.1 to 16.9, with an average value for all hybrids of 12.3. The stem diameter at base of the plant at the studied maize hybrids ranged from 10.5 to 20.1 mm, with an average value for all hybrids of 16.9 mm. The above-ground dry biomass production at the studied maize hybrids at physiological maturity of plant ranged from 5 to 13 tons per hectare, with an average value for all the ten hybrids of 8.5 tons per hectare. 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. The above-ground fresh biomass production at the studied maize hybrids at physiological maturity of plant ranged from 5.6 to 15 tons per hectare, with an average value for all hybrids of 9.7 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. Plant above-ground dry biomass ranged from 83.03 to 192.12 g. Plant above-ground dry matter, in average for the ten studied maize hybrids and for the specific conditions from South Romania and under drought of the year 2012, is composed of: 46.9% ear dry matter; 24.4% stem dry matter; 20.7% leaves dry matter; 6.6% husks, stalks and silk dry matter; 1.4% panicle dry matter. At physiological maturity of plant, stem humidity ranged between 6.3 and 30.2%, and leaves humidity ranged between 5.6 and 29.1%.
