Última Anfälligkeit von Leguminosen gegenüber Meloidogyne hapla Organic Eprints Reents, Dr. H. J.; Egerer, Johanna; Hermann, A.. Green manure legumes are a necessary element of organic crop rotations. However, they are able to propagate nematodes especially Meloidogyne and Paratylenchus species. The results of a pot experiment showed that plant species of the genera Pisum, Vicia, Trifolium had a higher propagation rate of Meloidogyne hapla than salad Latuca sativa while plant species of the genera Medicago and Melilotus were less susceptible to infestation of nematodes. It is concluded that crop rotation management especially in vegetable production has to consider the different susceptibility of the legumes and further research has to test more species and varieties.

Ano: 2009 URL: http://orgprints.org/14374/1/Reents_14374.pdf Intercropping with grain legumes increases N and S concentration and N:S ratios of wheat grain in European organic farming systems Organic Eprints Kasyanova, Dr E; Gooding, Dr MJ. Field experiments were conducted in three successive growing seasons (2002/03 to 2004/05) at different sites within Europe. Treatments included wheat intercropped with faba bean in both replacement and additive designs, both autumn and spring sowing, and at one site, wheat intercropped with pea. Irrespective of design, sowing season, site, or grain legume used, intercropping increased the N and S concentration, and the N:S ratio in wheat grain.

Ano: 2006 URL: http://orgprints.org/7484/1/RDGIntecrop.doc Intensivierung und Differenzierung des Leguminosen-Anbaus unter Berücksichtigung der Nematoden Organic Eprints Reents, Hans Jürgen; Egerer, Johanna; Baresel, Jörg Peter; Herrmann, Andreas. Zusammenfassung Um Empfehlungen für eine Erhöhung des Anteils der Leguminosen in Ökologischen Anbausystemen bei gleichzeitiger Erweiterung des Artenspektrums zu erarbeiten, wurden die Arten Trifolium subterraneum (Erdklee), Trifolium campestre (Feldklee), Medicago orbicularis (Schneckenklee), Medicago minima (Zwergschneckenklee) und Medicago truncatula (Einjährige Luzerne) in Verfahren des Lebendmulches und der Gründüngung untersucht. Besonders interessant für Mischkulturen hat sich der Erdklee erwiesen, für kurzzeitige Gründüngung die Einjährige Luzerne. Die enge Abfolge von Leguminosen birgt die Gefahr der Unverträglichkeit durch Nematodenbefall speziell mit Meloidogyne und Paratylenchus. In einem Gefäßversuch zeigte sich, dass die Arten der Gattungen... Tipo: Conference paper, poster, etc. Palavras-chave: Crop health; Quality; Protection Crop combinations and interactions. Ano: 2009 URL: http://orgprints.org/16214/1/Reents_et_al_2009_Leguminosen_Nematoden.pdf Tærskler til udsædsbåren bygbladplet Organic Eprints Pinnschmidt, H.O.. Overskridelse af den nuværende tærskel af 15% frøsmitte vil formodentlig kun i modtagelige sorter som Lux og Prestige give anledning til høje bladpletepidemier og dermed højt risiko for høje udbyttetab. Mit forslag er derfor: tærsklerne sættes ned (5%) for sorter i PVO gruppe 3, tærsklerne bliver som de er (15%) for sorter i PVO gruppe 2, tærsklerne sættes op for sorterne i PVO gruppe 1 (25%); tærsklerne er ikke nødvendige for sorter i PVO gruppe 0. (Faktisk vil man i praksis sandsynligvis ikke kunne finde 25% frøsmitte i sorter i PVO gruppe 0 og/eller 1.)

Ano: 2006 URL: http://orgprints.org/7935/1/7935_paper.doc Förbättrat skydd mot skadeinsekter genom nyttjande av synergieffekter mellan biologisk kontroll och styrd växtföljd Organic Eprints I denna studie vill vi utveckla ett odlingssystem som ger förutsättningar att öka och sedan bibehålla höga populationer av naturliga fiender inom gården och samtidigt genom en styrd växtföljd bryta skadegörarnas populationsutveckling. Detta skapar en god synergieffekt för reglering av skadegörarpopulationer, ökad produktionssäkerhet och förbättrad ekonomi för grönsaksodlarna. Studien kommer att kombinera kunskap från tillämpad forskning inom biologisk kontroll med kunskap från kemisk ekologi. Parasitstekeln Trybliographa rapae (Hymenoptera:Figitidae) är en viktig populationsregulator av skadegörare inom släktet Delia, som innefattar t.ex. lilla kålflugan (D. radicum), lökflugan (D. antiqua) och borststjälkflugan (D. platura) som angriper bönor.

Ano: 2024 Bestimmung der optimalen Aussaat- und Umbruchtermine einer überwinternden Leguminosen-Gründüngung für die nachhaltige Bekämpfung pflanzenparasitärer Nematoden im ökologischen Gemüsebau Organic Eprints Entwicklung einer nachhaltigen Fruchtfolgestrategie basierend auf dem Anbau einer überwinternden Leguminosen-Gründüngung zur Stickstoffgewinnung in Kombination mit einer Bekämpfung des Wurzelgallennematoden Meloidogyne hapla. Im speziellen geht es darum, die Aussaat- und Umbruchtermine der überwinternden Leguminosen-Gründüngung an die Biologie von M. hapla anzupassen, so dass es nicht zu einer Vermehrung der Nematoden kommt. Die Ergebnisse tragen zu einer Verbesserung nachhaltiger Verfahren der Nematodenbekämpfung im Ökolandbau bei und schließen Lücken bei der Entwicklungsbiologie von M. hapla während der Wintermonate.

Ano: 2024 Effect of intercropping on disease severity in organic farming Organic Eprints Daniel, Marie. In order to improve plant quality in organic farming, DARCOF launched studies on crop management, and among them, research on intercropping, defined as the growing of two or more species simultaneously in the same field during a growing season. The aim of this study was to evaluate the effect of intercropping on disease severity. The fist part of this report presents the context of this study and the research center where this work took place. Then, the literature review approaches the different systems on which intercropping is based. This is followed by methods used and the results. To finish, a discussion points out the conclusions of this work and its limitations. In this study, the levels of all diseases were very low. Intercropping had a...

Ano: 2006 URL: http://orgprints.org/11464/1/11464.pdf Samdyrkning af kartofler og hestebønne samt dyrkning af hestebønne på kamme Organic Eprints Bertelsen, Inger. Samdyrkning af kartofler og hestebønne forsinkede ikke spredningen af kartoffelskimmel. Der var ikke tilstrækkelige angreb af bladlus til, at der kunne påvises en effekt. Dyrkning af hestebønner på kamme gav en bedre rodudvikling og flere rodknolde. Disse resultater kommer fra forskning under FØJO II.

Field experiments with spring barley (Hordeum vulgare L.) and field pea (Pisum sativum L.) were carried out in three subsequent growing seasons 2004 to 2006 at the Hessian State Estate Frankenhausen located near Kassel in Central Germany. Spring barley and field pea were sown out as sole crops and intercropped with different seed rates in replacement and additive design, using two sowing modes: row by row (IC) and mixed intercropping (MC). Intercropping (IC and MC) was able to increase grain yield in most of the treatments. The Land Equivalent Ratio (LER) was always higher than 1, indicating that plant growth factors were used more efficiently by the intercrop than by the sole crop. Besides, the N content in spring barley grain was increased by... Tipo: Conference paper, poster, etc. Palavras-chave: Crop health; Quality; Protection Crop combinations and interactions. Ano: 2007 URL: http://orgprints.org/9755/1/9755_Dahlmann_Vortrag.pdf Yield, pest density, and tomato flavor effects of companion planting in garden-scale studies incorporating tomato, basil, and Brussels sprout Organic Eprints Bomford, Michael K.. Companion planting is a small-scale intercropping practice often associated with organic or biodynamic gardening. Two garden-scale studies tested popular companion planting claims by comparing garden beds devoted entirely to one of three or more test crops (monocultures) to all possible two-crop mixtures (dicultures) of the same species. A third study evaluated effects of planting density and crop ratio in three dicultures using a novel experimental design to create gradients in both factors. All studies incorporated basil (Ocimum basilicum L.), Brussels sprout (Brassica oleracea L.), and tomato (Lycopersicum esculentum Mill.). A preliminary study also included snap bean (Phaseolus vulgaris L.), radish (Raphanus sativus L.) before Brussels sprout, and...
