Tillage systems are sequences of operations (tilling, planting, fertilization, pesticide application, harvesting and residue chopping or shredding) which affect the physical and chemical properties of the soil, which in turn affect plant growth. It is essential to develop a right tillage system in crop production, in order to achieve high yields, using machines rationally and effectively. This paper has been released to emphasize the importance of tillage and the importance of choosing the tillage system, in order to achieve qualitative and quantitative superior yields, protecting in the same time the environment. In Almos Alfons Mosel Handels Group, during 2015-2017, sugar beet crop was cultivated in two tillage systems: conventional system and conservative system. The varieties used in the conventional system were Clementina, Magistral, Gorilla, Marcus, Damian, and in the conservative system only varieties Magistral and Damian. Efficiency is presented only for these common varieties, to highlight the differences between two variants of tillage systems. In addition to the evolution of soil properties and the efficiency of the tillage system on the biotic factor, we followed the evolution of economic indicators that establish economic efficiency. Economic efficiency is an instrument for evaluating activity, which helps us make the best decisions. The calculation of economic efficiency, at Almos Alfons Mosel Handels Gmbh, represent an important activity because it shows the connection between the resources used and the results achieved. The indicators analysed ware: average production, total expenses, sales revenue, agricultural subsidy, turnover, gross profit, net profit, profit rate. These indicators have been calculated on the basis of the technological data, specific to each tillage system and each year in the study. Under no-tillage system, represented by sowing directly in the crop debris of the pre-crop (mustard), economic indicators have set higher values. Thus, we can conclude that this no-tillage system has a rate of profit that is higher than that obtained under the conventional tillage system.
