Diversity of cormophytes from 3 sites (Bodrog Bezdin and Cenad) belonging to Mureş Floodplain Natural Park, is analyzed in terms of number of species, families and biological types. Overall in 2013 we studied 124 plots, most with cereals (wheat, barley and oats) and corn. The degree of weed is expressed as a percentage (%) of the soil surface covered their aerial parts and the projection on the ground. Vascular flora of weeds is represented by 205 species belonging to 40 botanical families. The average number of weed species per plot ranges between 16,70 and 19,5, in the case of cereals and 15,25 to 20 in the case of main weeding species (corn and sunflower). Specific biodiversity in the weeds group is poorly correlated or uncorrelated with the soil properties (pH and humus content) and size of the plots studied.
