abstract:
The experiment was carried out in Frankamionka village near Zamość, in the years 2004-2006. Subject of the study were weeds in maize canopy (“Veritis” cultivar, FAO 230-240) for silage. Varied cropping systems (sole cropping, strip intercropping) and three levels of tending (mechanical, mechanical-chemical, chemical) were the experimental factors. Maize for silage was planted between 25th April and 5th May. Species composition, weed density and air dry weed weight were analysed in the third decade of August. It was proved that weed infestation of maize depended on cropping systems and tending levels. Strip intercropping system caused decrease of weed density in maize canopy in comparison with sole cropping. Mechanical-chemical treatments revealed a high level of weed control. Glainsoga parviflora L., Echinochloa crus-galli (L) P. Beav., Amaranthus retroflexus L. and Chenopodium album L., were the dominant taxons.
