Abstract

Recently weed seed content of soils in Hungary has increased dramatically. This leads to severe weed problems even at later growth stages of the crop plants. In this study late-emerging weed populations were surveyed and characterized in a site-specific manner at a 9.2 ha field. Furthermore their effect on maize and future crops was evaluated. At selected sampling sites weeds were removed manually at different phases of crop development, newly emerging weeds surveyed and seed production by the major weeds determined. An evaluation of the data showed, that weeds emerging at later stages of maize development do not necessarily reduce crop yield significantly. However, they may interfere with maize harvest efficiency and the weed seeds produced contribute significantly to the soil weed seed bank thereby increasing weed problems for future years or even decades.
