The choice of soil tillage systems adapted to the pedo-climatic conditions and crop requirements so that the yield and economic efficiency should be attractive for farmers, as well as the modernization of agricultural machinery and implements suitable for this system are expected to expand in the future and to contribute thus to the sustainable development of agriculture, to the improvement of soil fertility and environmental protection. The promotion of conservation agriculture system in versions adapted to the soil conditions with mid-heavy texture and to the requirements of the main crops in the south of Romania which should provide competitive productions, both quantitatively and qualitatively, with reduced costs and high profit. Â The research has been carried out at the Valul lui Traian Station for Agricultutral Research and Development. The experiments were placed according to the method of subdivided plots, in three repetitions, with tillage systems, towards water conservation and economical optimization of the agricultural management and consisted of the following versions: the level of water supply (three graduations); deep loosening of the soil (two graduations); basic tillage (three graduations). Soy reacts well to irrigations, the yield being very significant and ensured statistically. By analyzing the production data obtained as an effect of the interaction between the three factors and given the no irrigation/no chisel plow/vibromix version, all the versions cultivated in conditions of water supply/chisel plow and no chisel plow have statistically ensured production growth that is significant, distinctly significant and very significant. Soy uses well the water administered in norms of 50% of the AHI, obtaining higher yields even than those obtained in conditions of irrigation with 100% of the AHI.
