Abstract

The present paper presents the results of an experiment with different tillage referring to soil moisture in dynamics, the corn plants height and the grain yield. The variants have been: v1= plowed soil in autumn and drilled after seedbed preparation by harrowing, v2= plowed soil in autumn and drilled in the spring without seedbed preparation, v3= no till without mulch layer and v4= no till with mulch layer. The results show that the main role of tillage is to keep water into the soil for roots. No tillage condition determines the compaction of shallow soil layer of 3-5 cm which extracts the water from beneath and loses it by evaporation. Direct drilling requires the presence of the mulch layer which reduces evaporation.
