The purpose of the paper was to estimate the Gini coefficient in order to characterize the concentration and distribution of the farm dealing with maize cropping in Romania. In this purpose, a suitable mathematical model was used for different intervals of owned land, as follows: G=D_x/2x = (∑ ⁿ_i=1 ∑ ⁿ_j=1 | xi - xj |) / 2 x n ². The Gini coefficient had the values: 0.595 in 2007 and 0.640 in 2012, reflecting that the farms have an unequal repartition, being more concentrated to the farms with a smaller size. However, in the analyzed period, 2007-2012, it increased the percentage of the smallest farms with under 0.1 and 1 ha, it was reduced the share of the farms with 1-2 ha, and also of the ones with 2-5 ha. Also the weight of the farms with 5-10 ha declined. And, the share of the farms with over 20 ha increased from 0.42 % in 2007 to 1.24 %. The percentages changes because the number of farms growing maize decreased by about 28.42 %. The causes could be the following ones: the orientation of the farmers to the crops with a higher revenue than maize, because of the high production, the maize price was enough small, and the impossibility to work the land by a part the oldest population or deaths among old people owning land. As a conclusion, it was noticed a slight a positive aspect that the share of the farms larger than 20 ha increased to 1.24 %. The improvement of farm structure in Romania is still a long process and the best solution to shorten it is as farmers to join in associative forms.
