Studies on the establishment of conservation technologies of tillage mechanization used in wheat crop, under soil specific conditions of the NE area of Romania

Abstract

In the autumn of 2007, for establishing the conservation technologies of tillage mechanization in wheat crop, in the North-Eastern Romania, six variants of technologies were tested. In every variant, we have determined the qualitative indices for each equipment and the energetic and exploitation indices for each unit. After sowing, we have determined for each variant soil resistance to penetration, mean diameter of soil structure and hydrostability of these elements. We have also determined the fuel consumption per hectare for the mechanized tillage, necessary for establishing the field crops. In order to establish the mechanization technologies of soil tillage, we had to take into account the way of plant growth and the obtained yields. Therefore, we have determined the number of raised plants per square meter, measured the plant height and, finally, we have established the seed yield per hectare. Based on the results obtained in these trials, we have evaluated the variants of technologies and established which of them corresponded to the requirements of soil conservation in wheat crop.
