Common amaranth (Amaranthus retroflexus L.) appears later in crop rotations rich in corn and soybeans. Under cool conditions, wild radish (Raphanus raphanistrum L.) was noted in sunflower crops. In winter wheat and perennial grass crops, the percentage of wintering, perennial and rhizomatous weeds increases in the second year, such as: white cowslip (Melandrium album L.), high-ribbed cowslip (Sisymbrium altissimum L.), field bindweed (Convolvulus arvensis L.), and pink thistle (Cirsium arvense L.) in the amount of up to 0.2–3.0 pcs./m2. Weed coenosis in five-field crop rotations was formed due to spring weeds, in particular: blue mouseweed 46.4–80.9%, black nightshade 0.6–0.9%, white quinoa 12.1–39.6%, pepper mustard 2.2–8.6%, 1.6–4.0% others, as well as 0.4–1.0 wintering, 0.1–0.7% root-shoot weeds. When using no-till cultivation methods in five-field crop rotations of the grain-forage-feed type, it was found that during plowing, the contamination of crops is lower than during no-till cultivation by 1.3–5.4 times, depending on the crop. In general, on average, the number of weeds during plowing is 2.4–2.6 times less. During no-till cultivation in early spring crops, the share of blue fescue (Setaria glauca L.) increased to 60.3–94.4%; the share of dicotyledons reached 39%, the main representatives of which were: white quinoa – 4.4–19.6%, black nightshade – 2.6–21.8%.
