The three field experiments were carried out in 1994-96 at Kruszyn Krajenski near Bydgoszcz on a loose sandy soil to investigate the influence of sprinkling irrigation and different nitrogen rates on weed infestation of fodder beet canopy. The influence of irrigation and fertilization on weed infestation of fodder beet was modified by the course of weather conditions during the period of the study. Sprinkling irrigation increased fresh and dry matter of weeds as well as their number on the surface unit. The composition of weed species in the fodder beet canopy was also influenced by irrigation. The most common species were following: Setaria viridis, Chenopodium album, Viola arvensis, Galinsoga parviflora. Nitrogen fertilization usually decreased the number of weeds both on non-irrigated plots as well as on irrigation fields
