Abstract The article shows the influence of crop rotation on weed infestation of corn at the beginning and end of its vegetation. It has been proven that among the row sowing crops the cleanest corn area was after spring barley, and among the cultivated crops – after sugar beets. The use of reseeding of different duration negatively affected weed infestation and yielding capacity. Yellow bristle grass (Setaria glauca) and barn grass (Echinochloa crus-galli) turned out to be among the main late spring weeds of corn, the average share of which over three years varied from 33.5 and 35.5 to 42.8 and 39.3%, respectively, depending on the crop rotation
Key words corn, predecessors, non-herbicidal technology, weeds infestation, yielding capacity
