Diversification of crop sequences (WP 1): Perennial weed species can be managed when cover crops / green manure crops are included in the crop sequence but interventions must be species dependent, e.g. Elytrigia repens can be promoted by green manures because they prevent post-harvest cultivations. Cirsium arvense and Sonchus arvensis are two perennials that can be controlled by full-season grass-clover subjected to regular mowing for green manuring purposes and this measure has immediate application. Cover crops for diversification (WP 1):  Fast growing cover crops producing copious biomasses are generally useful for the suppression of weeds but need to be abandoned when severe infestations of Elytrigia repens require post-harvest cultivations for...

Crop diversification for weed management in North European organic arable cropping systems. Introduction to the study of international research-network on diversification and weed management: PRODIVA. Organic Eprints
Hofmeijer, Merel A.J.; Gerowitt, Bärbel; Krawczyk, Roman; Salonen, Jukka; Verwijst, Theo; Zarina, Livija; Melander, Bo.
The international research network PRODIVA aims to improved utilization of crop diversification for weed management in northern European organic arable cropping systems. The over-all aim is to support organic agriculture for the exploitation of crop diversification methods to improve weed management and still maintain a diverse weed flora. Hypothesized is that crop diversification can improve weed management while ensuring a diverse weed flora by the employment of: (I) pertinent crop sequencing that mitigates noxious weed species (II) improved cover crop establishment with selected competitive cover crop species (III) crop mixtures utilizing the resources better than sole crop species resulting in more weed suppression (IV) variety mixtures exerting a...

Farmers deserve credit for contributing to the weed surveys Organic Eprints
Salonen, Jukka; Hofmeijer, Merel A.J.; Zarina, Livija; Krawczyk, Roman; Verwijst, Theo; Melander, Bo.
Weed surveys were carried out in the PRODIVA project during 2015-2016 with a smooth collaboration with farmers. More than 200 fields were surveyed in six countries around the Baltic Sea. In addition to the weed observations in spring cereal fields we collected information about the farming practices in organic cropping.

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...

Geographical distribution of challenging weed species - Current knowledge in organic arable farming in the Baltic sea region Organic Eprints
Hofmeijer, Merel A.J.; Melander, Bo; Krawczyk, Roman; Verwijst, Theo; Zarina, Livija; Salonen, Jukka; Gerowitt, Bärbel.
They create a great source of agro biodiversity, generating habitats and food sources for other organisms; yet weeds have always posed the greatest challenge in Organic Agriculture from the perspective of production. Because of the specific agricultural management of this farming system, several groups of weed species have naturally adjusted. These can be highly competitive to the crop, acquire high inputs to remove and/or spread rapidly. In this leaflet we will describe the most challenging weed species in organic spring sown cereals in the geographical area of the Baltic sea, based on existing literature and information provided by extension services. We will show and discuss their distribution from country to country and propose a classification...

Problematic weed species in organic arable agriculture around the Baltic Sea - An expert database Organic Eprints
Hofmeijer, Merel A.J.; Melander, Bo; Krawczyk, Roman; Salonen, Jukka; Verwijst, Theo; Zarina, Livija; Gerowitt, Bärbel.
Weeds are a perpetual challenge in Organic agriculture. However, they serve multiple ecosystem services and a low competitive weed cover can be tolerated. Adding to this, is the fact that only a few species prove problematic for both the crop and the farmer. The international PRODIVA project researches the effect of crop diversity strategies on the diversity of weed communities, hypothesizing that by increasing the weed diversity, the development of problematic weeds will mitigated. A preparatory study was conducted to list the most problematic weed species in spring sown cereals in the countries involved with PRODIVA. For this a literature review was conducted in all participating countries, collecting local sources including grey literature. This was...

Implications - Specific annual and perennial weeds are a perpetual challenge in the process of tuning up sustainable Organic production. To utilize the perspective of agro-biodiversity would both improve crop yields as well as conserve the ecosystem services of this agriculture system. The successful use of crop diversity strategies provides an additional tool in the toolbox of the farmers, giving them a) an overview of problematic weed species and b) the opportunity to plan their crop diversity based weed management over the course of years in the future.

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...

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,...

PRODIVA WP2. Crop mixtures for weed suppression. Annual Report 2015 Organic Eprints
Verwijst, Theo; Lundkvist, Anneli.
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, Uppsala, Sweden, in the summer of 2015. A substitutive completely randomized experimental 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...
