In this study, different tillage systems were compared in terms of their effects on physical properties of soil, task time, fuel consumption and crop yield. In the research, the seedbeds were prepared by four different tillage systems including minimum tillage with stubble (MTR), minimum tillage non-stubble (MT), conventional tillage with stubble (CTS) and conventional tillage non-stubble (CT). The crop sown into seedbed was maize (<I>Zea mays</I> L.). The result of study was shown that tillage systems with crop residue improved physical properties of the soil such as porosity, bulk density and compaction. Soil compaction was under 3.5 MPa in the all experiment plots. A clear difference in bulk density and porosity was detected in 0-10 cm depth. Bulk density was under 1.35 g cm<SUP>-3</SUP>, whereas porosity was over 50% in this depth for all treatments. The effect of tillage systems on crop yield was found statistically significant. The highest grain yield was 8719 kg ha<SUP>-1</SUP> on CT, because of intensive plant population. Among the systems, the lowest task time and fuel consumption were 4.0 h ha<SUP>-1</SUP> and 28.8 l ha<SUP>-1</SUP>, respectively on MT.
