This paper deals with results of a study on the effect of reduced tillage systems on weed status in wheat, corn and soybean. The tables show the interdependence of the number of weed species in the three locations and three tillage systems - conventional plowing, chizel and no-tillage. Based on the literature data and results obtained in this research, an opinion is given on the applicability of reduced tillage systems in the prevailing situation of weed status. In the prevailing situation with the presence of Johnsongrass (Sorghum halepense) in the fields, reduced tillage is applicable for the sowing of winter wheat, a dense crop which develops a high competition against weeds. Regarding the conventional tillage systems for the sowing of spring row crops, it must be timely, effective and combined with herbicide application, in order to control the status of perennial weeds.
