The four-year trial was conducted in north-western Slavonia (main arable crop producing region in Croatia) to evaluate the effects of different tillage systems on the water content of silty loam soil (Albic Luvisol) and yields of maize (Zea mays L.) and winter wheat (Triticum aestivum L.). The tillage systems compared were: conventional tillage; reduced conventional tillage; conservation tillage I; conservation tillage II (CM); no-tillage (NT). During the study period, there were one dry, two wet and one average season. Soil water content (SWC) was measured at 0-5, 15-20 and 30-35 cm depths on a monthly basis. Tillage systems had significant (P < 0.05) effects on SWC and yields. The highest average SWC in all seasons was measured under the NT system, followed by the CM system. In the second season, the highest yield was measured under the NT system while in all other seasons, it was under the CM system.
