The paper aimed to analyze the dynamics of maize production in Romania and the influence of cultivated area and maize yield on this output, using the empirical data provided by the National Institute of Statistics for the period 2007-2015. The analysis is based on various methods like the chained substitution of factors, and fixed indices, coefficient of correlation and determination, and regression function. In the analyzed period, the cultivated area with maize increased by 3.12 % reaching 2,604 thousand tons in 2015. Romania potential to produce maize is about 12,000 thousand tons, placing the country among the top producers in the EU-28. Maize is the most important cereal crop contributing by 47 % to cereal production. In 2015, maize yield accounted for 3,449 kg/ha being by 126 % higher than in 2007, but tge performance is still very low compared to other EU countries. The main changes in maize production were determined by average maize production (r = 0.968 and R2= 0.9386), and in a weak measure by cultivated surface (r = 0.080 and R2=0.0065. The same aspect relationships were confirmed by the regression functions between these indicators. As a conclusion, maize yield is the key factor increasing production. Maize culture is cultivated in an intensive production system in Romania. Farmers should be on the factors supporting production growth as follows: to use high value certificated maize seeds from hybrids with a higher production potential, to apply the corresponding agricultural works according to the modern technologies, to take into account the need of crop rotation, to assure the corresponding plant density per unit of surface, the adequate doses of fertilizers, to take care of pest control, to assure irrigation and also to assure the insurance of maize culture against climate phenomena. Maize production is important for internal consumption and also for export.
