| 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)”. |

| The data on weediness from the ongoing crop rotation experiment at the State Priekuli Plant Breeding institute were analysed on the basis of hypothesis that under-sowing in spring cereals can improve weed management. Grass/clover mixture (Trifolium pratense L. and Phleum pratense L.) as under- sowing in spring barley (Hordeum vulgare L.) was grown for one and two seasons in six field crop rotation. Numbers of weed plants in spring (BBCH 20 – 29) were recorded using 0.1 m2 big frame in 10 places; plant biomass of under-sown crops and weeds were sampled within 1.0 x 1.0 m squares after the first cut in the following year after harvesting of main crop (barley). The total of 28 weed species were registered. The most common species were Chenopodium album L.;... |

| The aim of the present study was to evaluate spring cereal(barley and oat)variety mixtures for their weed suppression ability in agroecological conditions of Latvia. It was concluded that in two-years tudy,investigated spring cereal variety mixtures did not show better ability to suppress weeds if compared to their pure components.Additional studies would be necessary to evaluate root development and allelopathic activity of crop and weed plants. |
