For establishing the best conservation technologies of tillage mechanization from NE Romania in grain maize crop, six technology variants were tested in the spring of year 2007. In each technology variant, we have determined the qualitative indices for every work equipment and the energetic and exploitation indices for each farm equipment. After crop sowing, we have determined for each variant, soil resistance to penetration, mean weighted diameter of soil structural elements and water stability of these elements. At the same time, we have determined the fuel consumption per hectare, for mechanized tillage and sowing. We have also found that when selecting the mechanization technologies of soil tillage, we should take into account the obtained seed yields. After the analysis of the obtained results, we have established the best mechanization technologies that ensured soil conservation conditions for maize crop.
