Abstract
The experiments were carried out within the Experimental Farm of the Agricultural University of Iasi, North East of Romania, on a cambic chernozem, with a medium level of fertilisation, with clay-loamy texture, pH of 6.7 and 3.5% humus content. The experimental soil tillage variants included: V-1 - disc harrow (2x), V-2 - paraplow, V-3 - chisel+vertical rotary harrow, V-4 - plough at 20 cm and V-5 - plough at 30 cm. The increase of the compaction level, reflected by the values of BD and CR, determined the increase of tensile strength of soil aggregates. The lower values of the tensile strength were determined for the conservative tillage treatments. Tillage systems influenced significantly the winter wheat yield.
