In this paper influence of two tillage systems for soils of heavy mechanical composition (conventional with bottom plough and ameliorative tillage system) is analyzed. The emphasis of research, in addition to other secondary effects, is focused on the yield and the cost of production of main field crops as relevant indicators of efficiency of plant production. Production of field crops with conventional tillage system gave satisfactory yields, characteristic for a given agro-climatic conditions (quantity and distribution of rainfall, soils of heavy mechanical composition). Ameliorative tillage system of soils of heavy mechanical composition in comparison to conventional system achieved significantly higher yields of crops in dry years (8.6% sunflower, 9.9% corn), and even more in years with a lot of rainfall (21% wheat). The research is necessary to continue in order to see the effects of ameliorative tillage system on other breeding plants, and also for observing the effects of continuous usage of this tillage system (in second, third, and fourth year of production).
