An experiment, conducted over the period 2008–2010, evaluated the effect of tillage system on the occurrence and species composition of anthropophytes in winter wheat, maize and spring wheat. Regardless of crop plant and tillage system, anthropophytes (73.9%), represented by archaeophytes and kenophytes, were the main component of the flora in the crops studied, whereas apophytes accounted for the remaining 26.1%. Most archaeophytes (13 species) were found in the spring wheat crop under no-tillage, while their lowest number (6 species) occurred in the spring wheat crop under conventional tillage. The only kenophyte, Conyza canadensis, was found to occur in the spring wheat and maize crops in the no-tillage system. The following taxa were dominant species among archeophytes: Geranium pusillum, Anthemis arvensis, and Viola arvensis (regardless of tillage system and crop plant), Anthemis arvensis (in spring wheat – conventional tillage), Echinochloa crus-galli and Setaria glauca (in maize – reduced tillage and no-tillage), Chenopodium album (in maize – no-tillage) as well as Apera spica-venti, Anthemis arvensis and Papaver rhoeas (in winter wheat – no-tillage).
