The aim of this study is to assess the weed suppressive ability of crop mixtures and impact of weeds on crop yield as a function of species and densities by means of field experiments and controlled experiments with mixtures of barley and pea, conducted in Sweden and Poland. The performance of crop mixtures was compared to the performance of pure crops with regard to their ability to suppress weeds. In the fields, natural weed populations were used while the controlled experiments employed Elytrigia repens or Sinapis alba as a model weed. Preliminary results from the controlled experiment in Sweden showed that the presence of a crop (sole crop or intercrop) significantly diminished the growth of E. repens. The ability to compete was lower in peas,... Tipo: Other Palavras-chave: Crop combinations and interactions; Biodiversity and ecosystem services; Weed management.

Annual Report 2016 Organic Eprints Verwijst, Theo; Lundkvist, Anneli; Krawczyk, Roman; Kaczmarek, Sylvia. The aim of WP2 is to assess the weed suppressive ability of crop mixtures as a function of species and densities, using a functional approach. During 2016, field experiments and controlled experiments with mixtures of barley and pea were conducted in Sweden and Poland. The performance of crop mixtures was compared to the performance of pure crops with regard to their ability to suppress weeds. In the fields, natural weed populations were used while the controlled experiments employed Elytrigia repens or Sinapis alba as a model weed. The purpose was to quantify weed suppressive ability of the crops, the impact of weeds on crop yield, and to identify crop traits responsible for the effects on weeds and crop yield. Preliminary results from the controlled... Tipo: Report Palavras-chave: Production systems; Biodiversity and ecosystem services; Weed management.

The suppression of weeds exerted by the crop plays a significant role for weed management in organic crop production. Crop species have different competitive abilities against weeds but also crop varieties vary in their suppression of weeds. Previous studies with varieties of spring cereals have demonstrated marked differences in the suppression of weeds caused by different attributes, such as stem height and leaf area index. However, little is known when different varieties of the same cereal species are mixed in different compositions both in terms of the number of varieties included and the seed rates at which they are established. Some studies have focused on yield and disease aspects but this study aimed to identify and select blends of cultivars of...

Prezentowane wyniki badań są częścią międzynarodowego projektu PRODIVA - Crop diversification and weeds (http://coreorganicplus.org/research-projects/prodiva) finansowanego przez Narodowe Centrum Badań i Rozwoju i realizowanego w ramach konkursu ,,Core Organic Plus”. Projekt skierowany jest na wspieranie bioróżnorodności jako ważnego elementu kierowania zachwaszczeniem w rolnictwie ekologicznym. W pracy zaprezentowano wyniki badań polowych prowadzonych w Polsce i Łotwie, które miały na celu uzyskanie informacji na temat cech odmian i mieszanek odmian zapewniających optymalną redukcję zachwaszczenia. W badaniach zastosowano łącznie dziesięć odmian jęczmienia jarego oraz sześć odmian owsa jarego. W badaniach wykonano pomiary masy chwastów, wysokości...

The presentation shows the actions taken within the framework of the project in 2015. In the first year of the project, field experiments were performed in Poland in the cultivation of barley and oat. 6 barley varieties and 3 oat varieties were taken into account. Varieties were sown in pure stands and in two-component mixtures. The main goal of the activities was to assess the potential of cereal mixtures to weed suppression. Besides weed biomass production a lot of other aspects were described to present traits considered to be responsible for weed suppression.

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...

Ano: 2018 URL: http://orgprints.org/33522/1/PRODIVA_WP2_Deliverability%20No.%20D2.3%20Scientific%20communication.pdf From practice to science and back – knowledge and information chains in PRODIVA Organic Eprints Gerowitt, Bärbel; Hofmeijer, Merel A.J.; Melander, Bo; Sonderskov, Mette; Krawczyk, Roman; Kaczmarek, Sylvia; Salonen, Jukka; Verwijst, Theo. To organize and manage the dissemination process has become a general task within international projects. Within the project PRODIVA (Crop diversification and weed management) we organized these chains as returning cascades between practice (advisors and farmers) and scientists in the Baltic area. A network of farmers was created in each participating region. We collected and used practical knowledge about dominating weed species in Organic spring cereal production. This data can be compared with monitored weeds in the regions. Together with the monitored weeds management data was collected on-farm. Relating this data to the results of experimentally investigated crop diversification tools, being subsidiary crops in the rotation, crop mixtures and variety...

The main reason for controlling weed abundance in agricultural crops is the risk for qualitative and quantitative reductions in crop yields. Although there are no simple standard solutions available for weed control in organic agriculture, however, some cultural practices—in particular, undersow in spring cereals—can be critical components of weed management. To study this thesis, specific research has been carried out in the CORE Organic Plus PRODIVA project in six northern European countries—Denmark, Finland, Germany, Latvia, Poland & Sweden. Density of weed species were assessed in 109 organic fields situated in different agro–ecological conditions of region. The highest number of weed species fixed in surveyed fields was 93 (in Denmark). The most... Tipo: Conference paper, poster, etc. Palavras-chave: Weed management.

Chwasty stanowią źródło różnorodności biologicznej terenów rolniczych, tworzą siedliska i są źródłem pokarmu dla innych organizmów, jednakże z perspektywy produkcji �w rolnictwie ekologicznym zawsze stanowiły duże wyzwanie. Kilka grup gatunków chwastów, ze względu na specyficzne gospodarowanie ekologicznym systemem rolniczym, naturalnie się dostosowało. Może to oddziaływać mocno konkurencyjnie na rośliny uprawne i wymagać dużej ilości nakładów w usunięciu i/lub ograniczeniu ich rozprzestrzeniania. W niniejszej ulotce opisano najbardziej uciążliwe gatunki chwastów w zbożach jarych uprawianych �w gospodarstwach ekologicznych w rejonie Morza Bałtyckiego, w oparciu o istniejącą literaturę oraz informacje dostarczone przez służby doradcze.
