The effects of tillage systems on a weed synusia, number of plants per species, composition, biomass were observed in winter wheat on the chernozem luvic oil during the period 2000/01-2000/03. A low-input technology consists of the following three tillage systems: conventional tillage system, mulch tillage and no-tillage system. The N rates of 60 and 120 kg/ha were applied in plots. The obtained results show that Chenopodium album and Agropyrum repens as annuals and Convolvulus arvensis as a perennial were the dominant species in the weed synusia. Tillage systems and the application nitrogen fertilizers have a great influence on weed control and the floristic composition, a number of both, species and plants per species, and the biomass of weeds of winter wheat. Conventional tillage and mulch tillage systems had better effect on weed control than no tillage systems. The number of weed plants per species and biomass were the highest in no tillage sistems especially in dry years.
