Abstract
The research paper presents the results obtained in the pedoclimatic conditions of Cluj-Napoca, Romania, concerning the control of Convolvulus arvensis L species. 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. The number of Convolvulus arvensis seeds increases with 169% at tillage variant with disk + rotary harrow, 77% of these being located in the first 10 cm soil depth.
