Weed infestation of cereal stubble-fields in the Lublin region

Abstract

Results presented concern the species composition, constancy (S) and indices of coverage (D) of weeds on the cereal stubble-fields on various soils in the Lublin region. The report was based upon 456 phytosociological records collected in 130 stands after harvest in the years 1975-1980. In total 245 weed species were found. They were the scarcest on loose sands - 65 species, and the most abundant on loess soil - 158 species. Each kind of soil was characterized by a specific species composition, various degrees of constancy and indices of coverage of weeds.
