Última PRODIVA, Crop species mixtures for weed suppression: Deliverability No. D2.3 Technical report Organic Eprints Verwijst, Theo; Lundkvist, Anneli; Pers Berglund, Anna; Krawczyk, Roman; Kaczmarek, Sylvia. The aim of the studies performed in PRODIVA working package 2 was to assess the weed suppressive ability of crop mixtures (spring barley + peas) compared to ability of pure crops to suppress weeds. The work was done by means of field trials in which natural weed populations were used while controlled experiments were used with Elytrigia repens or Sinapis alba as a model weeds. Over a period of three years, 5 field experiments and 9 experiments under controlled conditions were performed in Poland and Sweden. In all experiments, performance was assessed in terms of the crops ability to compete against weeds (AC). The ability to withstand competition from weeds (AWC) and the relative weed biomass in the intercrop, compared to weed biomass in the sole...

In order to assess the weed suppressive ability of a pea/barley crop mixture and the component crops in sole cropping, a controlled outdoor experiment was performed at The Swedish University of Agricultural Sciences, Ultuna, Sweden, in the summer of 2015. A substitutive completely randomized ex-perimental design was used with seven treatments and six replicates. The weed species planted in the experiment was Elytrigia repens (L.) Desv. ex Nevski. At three occasions leaf area index (LAI) was optically measured using a LAI-2200C Plant Canopy Analyzer. Two destructive harvests were taken in order to assess the biomass of different plant parts from each of the component species. At the first harvest leaf area was measured in order to calibrate the optical LAI... Tipo: Thesis Palavras-chave: Production systems; Biodiversity and ecosystem services; Weed management.
