Weed infestation of fields with Westerwolds annual ryegrass (Lolium multiflorum var. Westerwoldicum)

Popis výsledku v původním jazyce

Westerwolds annual ryegrass (Lolium multiflorum var. Westerwoldicum) is cultivated in various parts of the world as a fodder crop for beef cattle, generally mixed with soya or maize. Efforts to improve the annual production of high-quality fodder has increased the importance of cultivation of Westerwolds annual ryegrass. The objective of the paper is to assess weed infestation on fields with Westerwolds annual ryegrass, i.e. to record weed species occurrence and to evaluate the relationship between crop coverage and weed species presences and abundances. The assessed lands were located in the cadastral area of Rebešovice (South Moravia, Czech Republic). The vegetation recording was made using phytosociological plost in June 2018. A total of 36 weed species were identified in the plots, where annual weeds Anagallis arvensis and Oxalis fontána were found as most abundant. Datura stramonium or Echinochloa crus-galli, for example, were found more frequently on plots covered by sparse crop, pointing to low crop ability to suppress several weeds. Weed species composition changed very little according to the crop coverage. The most problematic weeds in fodder crops are poisonous species, we found Aethusa cynapium, Datura stramonium, Equisetum palustre, Euphorbia helioscopia, Fumaria officinalis and Solanum nigrum, which can cause health problems after cattle feeding.
