Spring cereal variety mixtures and their relevance for weed suppression in agroecological conditions of Latvia

Summary in the original language of the document

Good weed suppression ability is required characteristic for crops grown in organic conditions. Some authors report that crop variety mixtures can be more effective in weed suppression than the varieties in pure sowings (DidonandRodriguez,2006). Some other studies show that variety mixtures do not suppress weeds better than their pure components(Kautetal.,2008). The aim of the present study was to evaluate spring cereal(barleyandoat)variety mixtures for their weed suppression ability in agroecological conditions of Latvia. This report includes some results from the ERA-NET CoreOrganicPLUS project “Crop Diversification and Weeds(PRODIVA)”.
