%X Weed infestation was monitored in an organic crop rotation system in South Bulgaria. 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.
