The influence of basic tillage and fertilizer on weediness of sunflower crops The article presents the influence of the basic tillage and fertilization system on weediness of sunflower crops in the stationary crop rotation during 2016–18 in the conditions of the eastern part of the Forest-Steppe of Ukraine. The largest number of species of weeds and contaminants in crops was found on the background without fertilizers (plowing) and on the organic-mineral intensive background (manure aftereffect, 30 t / ha + N30P30K30, chiseling). The type and level of weed infestation of sunflower crops significantly depended on the studied factors. Keywords: sunflower, crop rotation, tillage, fertilizers, weeds, herbicides.
