Abstract


The purpose of this paper is determining the specific influences which soil tillage and the pre-emerging plant have on the economic efficiency of the soybean culture in the area of the Somesan Plateau. The economic efficiency of the soybean culture is mainly determined by the crop level and the production costs, so that for the soybean culture a profit between 128 - 153 lei/ha is recorded, which varies depending on the soil tillage. Thus, with the classical alternative, a profit of 135 lei/ha is recorded, and with the unconventional chisel and paraplow soil tilling alternatives values of 140 - 153 lei/ha are recorded. The profit achieved in the (a4) alternative, tilled with the rotary harrow, is 128 lei/ha, smaller than both the profit recorded in the classical system alternatives and the unconventional systems ones. Regardless of the fact that soybean is cultivated after wheat or corn, the profit rate is maximal 16.25 - 16.32% in the paraplow tilling alternative, respectively 13.57-13.58% in the classical plowing alternative and 13.66 - 13.69% in the rotary harrow soil tilling alternative. Variations of the profit rate depending on the pre-emerging plant were identified only with the chisel alternative, for which cultivating soybean after wheat achieves a rate of profit of 14.89%, comparatively with 13.01%, when soybean was cultivated after corn.
