Abstract
A phytosociological classification and the characteristics of weed communities developing in root crops of the Kałuszyńska Upland are given in this paper. The presence of three associations: Digitarietum ischaemi, Echinochloo-Setarietum and Lamio-Veronicetum politae, as well as of two communities: Setaria pumila-Setaria viridis and Panico-Setarion alliance, has been found. The differentiation in trophic and soil moisture conditions of habitats results in the floristic diversity of communities, divided into lower phytosociological units. Two variants have been distinguished within the association Digitarietum ischaemi, whereas Echinochloo-Setarietum has been divided into 2 subassociations and 6 variants.
