Agronomic performances of self-reseeding legumes on alkaline soil under Mediterranean climate Organic Eprints
Ayoub, Dr. Mohamed.
Self-reseeding legumes are an essential component of the Mediterranean natural resources. Germplasms collected from the Mediterranean region were introduced in Australia and subjected to an extensive breeding. Species were then re-introduced in their original habitat where they were object of different important researches. Despite all the efforts made to select appropriate species and varieties, well-adapted cultivars have not been yet identified for all situations. At the experimental farm of the Mediterranean Agronomic Institute of Bari, Italy, agronomic performances of 15 cultivars of self reseeding legumes were compared on an alkaline soil to evaluate their possible use in organic agriculture systems. 10-m2 plots were used in a complete randomised...

Biological control of common bunt (Tilletia tritici) in organic farming Organic Eprints
Borgen, Anders; Davanlou, Mehrnaz.
Common bunt (Tilletia tritici syn. T. caries) is a significant seed borne plant disease in organic agriculture. General measures in ecological crop protection like crop rotation and manuring practice has in practice failed to control this disease, and direct seed treatment therefore seems to be necessary to ensure yield and food quality. Current study indicate that biological control can give successful control without negative effects on seed germination vigour. A combination of biocontrol agents and milk powder improves the effect of the biocontrol. Application of compost to the soil increases the frequency of this disease. The potential role of biocontrol within the principles of ecological disease management is being discussed.

Control of seed borne diseases in production of organic cereals Organic Eprints
Nielsen, Bent; Borgen, Anders; Kristensen, Lars.
In production of organic seed it is important to have some control measures on seed borne diseases to avoid propagation and spread of serious diseases. Due to lack of acceptable treatment methods the only way for the moment is to discard seed lots with unacceptable infections. Experiments have been started to find new and alternative methods for controlling seed borne diseases. In spring barley the results show good effect with 5% acetic acid on leaf stripe (Pyrenophora graminea) but problems with unacceptable effects on seed germination have to be solved. The old method with hot water treatment can be used and the results indicate good results against leaf stripe using water at 55°C. The effect of hot water was enhanced by first soaking the seeds in water...

Effect of seed treatment with acetic acid in control of seed borne diseases Organic Eprints
Borgen, Anders; Nielsen, Bent.
In field trials, seed treatment with acetic acid has reduced common bunt (Tilletia tritici) in winter wheat by 91.5-96.2% and by 83% in spring wheat without negative effects on germination vigour of the seeds. Leaf stripe (Pyrenophora graminea) in spring barley was reduced by 93,4%. Acetic acid is a cheap and environmental friendly fungicide with a possible scope of application especially in organic agriculture, where conventional pesticides are prohibited.

Effect of seed treatment with milk powder and mustard flour in control of common bunt (Tilletia tritici) in wheat and stem smut (Urocystis occulta) in rye Organic Eprints
Borgen, Anders; Kristensen, Lars.
In field trials mustard flour was able to control seed borne infection by common bunt (Tilletia tritici) in wheat without decreasing the germination vigour of the treated seeds. Full control of common bunt by coating the seeds with milk powder could only be achieved at doses which reduced germination vigour of the seeds. Mustard flour can be recommended as a seed treatment in organic agriculture while a treatment based on milk powder should be developed in combination with biological control. Both milk powder and mustard flour can be used to control stem smut in rye (Urocystis occulta).

Hvedens stinkbrand - en udfordring for principperne for økologisk jordbrug Organic Eprints
Borgen, Anders.
I afhandlingen beskrives principperne for økologisk plantebeskyttelse og der argumenteres for, at en plantesygdom som stinkbrand primært bør forebygges frem for at blive bekæmpet i et økologisk dyrkningssystem. Stinkbrandens biologi analyseres med henblik på at finde mulige forebyggende dyrkningsmetoder. Endvidere undersøges mulige bekæmpelsesmetoder, som er tilpasset økologisk jordbrug. Det konkluderes, at der findes forebyggende metoder, og at det er sandsynligt, at en systematisk udnyttelse af disse vil kunne forhindre hovedparten af problemerne med sygdommen. Det konkluderes endvidere, at der er muligheder for bekæmpelse i økologisk jordbrug, som kan bruges som sikkerhedsnet under dyrkningssystemet. I afhandlingen gengives 6 eksperimentelle...

Le pouvoir de compétition des variétés de blé face aux adventices: un critère de sélection important en Agriculture Biologique Organic Eprints
Neuhoff, Daniel; Eisele, J. A..
Le contrôle des mauvaises herbes en culture céréalière nécessite une rotation raisonnée mais également une bonne gestion de la lutte mécanique. De ce point de vue, la manière la plus efficace pour contrôler les mauvaises herbes est l’usage de la bineuse. Pratiquement, cette méthode est désavantageuse car elle nécessite de larges interlignes (plus de 17 cm) et un rythme de travail réduit. L’étrille par contre est moins efficace mais implique moins de contraintes techniques. Soulignons que ces deux méthodes dépendent largement des conditions météorologiques et sont coûteuses (temps, carburant, machines). Une méthode indirecte permettant de contrôler les adventices consiste dans l’augmentation du pouvoir de compétition de la plante cultivée face aux...

Managing crop nitrogen and soil dynamics Organic Eprints
Salon, Christoph; Hauggaard-Nielsen, Henrik.
Despite extensive research grain legume seed protein content and yield remains low and unstable. Grain legume performances in the cropping system are highly dependent upon N nutrition of the crop relying on root assimilation of soil N in combination with symbiotic fixation of atmospheric dinitrogen. In order to improve the competitive ability of grain legumes for growth resources an enlargement of the crop surface area production in combination with a judicious management of both inputs and N acquisition (and allocation to the harvested organs) is needed. Competitive ability implies to take into account economical constraints and the crop production effect on the environment, reducing the amount of N remaining after the crop harvest preventing N...

Ökologischer Sojaanbau in kälteren Gebieten Deutschlands? Organic Eprints
Paffrath, Andreas; Henneberger, Matthias; Mayer, Jochen.
Bisher können Sojabohnen in Deutschland nur in klimatisch begünstigten Gebieten wie z.B. im Raum Freiburg, der Oberrheinebene und in Südbayern einigermaßen erfolgreich angebaut werden. Aufgrund ihrer hohen Temperaturansprüche sind für Soja nur Lagen geeignet, in denen auch Körnermais angebaut werden kann. Die Aussaat erfolgt von Ende April bis Anfang Mai. Neuere Sorten könnten jedoch auch für den Sojaanbau in etwas kälteren Gebiete Deutschlands interessant sein. Zur Klärung dieser Frage wurden im Jahr 2001 am Gartenbau-Zentrum Köln-Auweiler der Landwirtschaftskammer Rheinland(Jahresmitteltemperatur: 9,5 °C) sechs Soja-Sorten, und auf dem Versuchsgut der Universität Kassel-Witzenhausen, der Domäne Frankenhausen (nördlich von Kassel;...

Perennial survival of common bunt (Tilletia tritici) in soil under modern farming practice Organic Eprints
Borgen, Anders.
Three years of field trials in Denmark have shown that common bunt (Tilletia tritici) is able to infect wheat in crop rotations with several intercrops between susceptible crops. This contradicts most previous literature which concluded that common bunt is a seed-borne pathogen only able to infect through the soil in cases where wheat is grown in two consecutive years. It is argued that the reason for this change in pathogenicity can be explained by a change in farming practice

Proteinqualität alter und moderner Winterweizensorten und -zuchtstämme Organic Eprints
Hagel, I.; Spieß, H.; Schnug, E..
Da Weizen aus biologisch-dynamischem Anbau gegenüber konventionellem Weizen häufig bedeutend niedrigere Proteingehalte aufweist, sollte die Möglichkeit der Verbesserung der Proteinqualität über die Sortenwahl geprüft werden. Dazu wurden 12 Winterweizensorten (moderne und ältere Sorten, Landsorten bzw. daraus erhaltene Zuchtstämme) aus einem unter biologisch-dynamischen Verhältnissen durchgeführten Vergleichsversuch (Ernte 1994) wurden auf ihre Anteile an salzlöslichem Protein, Gliadin und Glutenin sowie auf den Grad der Kleberviskosität (Glutenindex) untersucht. ► Durch die sortenbedingte Variationstanden die Protein-N-Anteile nur in schwacher Beziehung zum N-Gehalt. ► Höhere Anteile Glutenin wurden durch geringere Anteile sowohl an salzlöslichem Protein...

Reduction of spore spread of common bunt (Tilletia tritici) via combining equipment Organic Eprints
Kristensen, Lars; Borgen, Anders.
The disease common bunt (Tilletia tritici syn. T.caries) has become a more frequent problem in Europe during the last 15 year. In organic farming, common bunt causes serious problems for seed producers, and many seed lots are discarded due to contamination with Tilletia tritici. Due to the biology of Tilletia tritici, with spores loosely attached to the surface of the grain, there is a risk that spores can be disseminated via grain handling equipment, including combine harvesters. Preventive efforts should focus on the role of grain handling equipment, and how the fungus life cycle can be broken. We have investigated the dissemination of spores via the combiner after harvesting infected fields. We conducted six trials over three years, counting the number...
