Effect of fertilization on weed biodiversity in long-term continuous winter rye.

摘要

Field studies were conducted during 2007-08 at the Research Station Brody of Poznan University of Life Sciences in Poland to determine weed community in winter rye as affected by cropping systems (crop rotation, monoculture) and fertilizer application (organic and mineral). Continuous winter rye led to the increase of weed number and fresh weight of weeds. The dominant weed species across all fertilizer application systems were Viola arvensis in crop rotation and Centaurea cyanus in monoculture. Fertilizer application changed the composition of weed population.
