The paper deals with results on the crop rotation effects on weed synusia including the weed number, floristic composition and biomass in winter wheat. The trial was carried out on leached chernozem in the experimental station Radmilovac of the Faculty of Agriculture in the vinicity of Belgrade (Serbia), during the period 2007-2009. According to the investigation it can be concluded that the cropping systems have their important application in the winter wheat production and a protective role in weed control. By rotating crops with different sowing dates and growth periods, contrasting competitive properties and dissimilar management practices, the regeneration niche of different weed species can be disrupted and increases in particular weed species prevented. The cropping pattern that included many various crops (two-crop rotation, three crop rotation) has a better effect in the weed control, especially in the control of perennial species, than in winter wheat continuous cropping.
