The floristic-phytocoenological study of weed in organic production of crucifers, the Brassicaceae family, was perfomed during the 2008 growing season in the village of Kisac, the Vojvodina Province (Serbia). Stands of the association Panico-Portulacetum oleraceae Loz. 1962, the alliance Polygono-Chenopodion Koch 1926, em. Sissing 1946, the order Chenopodietalia albi Tx., Lohm et Prsg. 1950, the class Stellarietea medie Tx., Lohm. et Prsg. 1950 were registered in the studied site. Twenty-one plant species make the floristic structure of the community. The maximum cover value was found for Portulaca oleracea L. (1130), the characteristic and dominant species of the association. Ambrosia artemisiifolia L. (370) was distinguished among the associated species. Species of wide distribution predominated in the chorological spectrum. The analysis of the represented life forms indicated a terophytic character of the described community.
