Abstract


The weed flora growing stubble-fields area is determined by soil features. Weeds found in cereal stubble-fields on black soils formed from sands and loams, medium and haevy alluvial soils as well as brown and chernozem rendzina soils are presented in the paper. The 273 phytosociological records were worked out. They were collected from 87 stands situated in 76 localities of Kielce region. The results showed that species number and species composition were dependent on the soils (black. alluvial, rendzina). The existance of 118 (medium alluvial soil) to 140 (brown rendzina soil) weed species, including 73 common for all of the soils considered, was found there. Relatively high per cent (29–35) of them belonged to perennial weeds. From 22 (brown rendzina soil) to 35 (heavy alluvial soil) of species reached high constancy degrees (V–III). Stellaria media, Myosotis arvensis, Polygonum aviculare, Agropyron repens and Cirsium arvense predominated on the all of the soil examined. Among the weed flora registered, 25 species, recorded only on rendzina soils, were distinguishable for that soils.
