The present study refers to the weed communities developing in the root plant fields. In 1991-95 at the end of August 240 phytosociological releves were made in the fields of potato and sugar beet. The results of floristic and site condition analysis proved high floristic diversity and species richness of plant communities. In the phytocoenoses occurring on brown soils evolved on gaizes and on rendzinas species regionally or nationally rare and threatened were found, among the others Aethusa cynapium var. agrestis, Papaver rhoeas, Geranium dissectum, Sherardia arvensis, Sedum maxium, Lathyrus tuberosus
