Best to cultivate before winter cereals was maize regarding weed infestation in our system. In spring chick-pea increasing Sinapis arvensis and Falopia convolvulus infestation was found, whereas the density of Alopecurus myosuroides and Avena spp. decreased. This is important for following winter cereals cultivation. 2005 published Ende der Nische, Beiträge zur 8.
