The contemporary development of agriculture aims to decrease material and energy demands of cultivation systems. The no-tillage system is a part of the rationalization measures. The presented article is dealing with the influence of the conventional tillage (KA) and no-tillage system (BA) on content of soil water, i. e. maximum (Wmax), average (W0) and minimum soil water content (Wmin), in heavy soils of the East-Slovakia Lowland. The vegetation periods of the observed years are classified from very dry (1999), humid (2000, 2002), very humid (2001) to extremely humid (1998). There was observed statistically significant influence of used systems of agrotechnical measures only in the case of minimum soil water content. This value was higher in case of no-tillage system about 4.3% of wilting point value during five observed years, i. e. in a soil profile 0-0,3 m about 3.0 mm of water layer and in a profile 0-0,8 m about 8.5 mm.
