Abstract. In spring wheat of weeds mixed type clogging – choreotrichia-minor – throughout the studied period was observed 12 species of weeds. Regular types of weed plants from monocots were avena fatua and setaria viridis; of the young dicotyledonous polygonum convolvulus, chenopodium album, amarantus retroflexus, erodium ciсutarium and fumaria officinalis; perennial cirsium arvense and sonchus arvensis. Reducing the depth of tillage contributed to the increase in the proportion of young monocotyledonous weeds by 4.6 % in the conventional treatment 2.9 % in the subsurface, 3.9 % for differentiated. In the species composition of weeds dicotyledonous young was a leader in the cultivation of spring wheat in grain-fallow crop rotation with a busy ferry. Constant species in the agrocenosis of spring wheat are from grass – oat grass common and green foxtail, perennial sow-Thistle field and the Thistle field, which is supported by studies of other researchers.
