To determine or accomplish the relation with soil tillage systems and herbicides applied on soy-bean, wheat and maize crop. Minimum tillage systems determine an increasing percentage of Convolvulus arvensis species at weeding, different depending on experimental variant and on crop: 11.2-39.1% at soy-bean, 0.9-4.2% at wheat and 11.9-24.4% at maize crop.
