Entwicklung eines zeitlichen und räumlichen Entscheidungshilfesystems gegen den Erbsenwickler (Cydia nigricana, Fabricius) Organic Eprints
Schieler, M.; Riemer, N.; Racca, P.; Saucke, Helmut; Clemenz, C.; Schwabe, K.; Müller, U.; Hammer-Weis, M.; Kleinhenz, Benno.
Pea moths (Cydia nigricana) can cause severe damages in pea crops (Pisum sativum). Larvae feed on the seeds in the pods and contaminate them with feces. In the cultivation of organic green peas 0.5 % damaged seeds lead to the denial of whole pea fields (Schulz & Saucke 2005). There can be a yield loss in forage peas and a loss of quality of seeds for propagation. Within the framework of the project to improve the spatial and temporal cultivation strategy of peas to get less damage due to pea moths, is the intention. For a better spatial and temporal cultivation strategy, the DSS creates a map with areas with an infestation risk factor. The higher the risk factor, the earlier the new fields should be cultivated. Therefore, the first part of the DSS...

Erbsenwickler (Cydia nigricana) in Gemüse- und Körnererbsen: Grundlagen zur Befallsprognose und Schadensprävention Organic Eprints
Riemer, Natalia; Schieler, M.; Kleinhenz, Benno; Racca, P.; Hammer-Weis, M.; Clemenz, C.; Schwabe, K.; Müller, U.; Saucke, Helmut.
Spatio-temporal distribution, combined with aspects of insect biology and ecology can influence the infestation risk of the key pea pest Cydia nigricana in vegetable- and field peas. The proximity of pea fields of the previous cultivation period highly affects the infestation potential of the moth. The presented study aims to monitor the infestation development in three different regions in Germany (North Hesse, Saxony, Saxony-Anhalt) in four consecutive years and to relate empirical pest incidences to key factors as crop abundance, the distance to previous pea fields, the pea plant phenology and climatic conditions. In a next step, these data will form the basis for the elaboration of a computer-aided decision support system, which assists farmers in...

Genetic parameters of growth and wood quality traits in Picea abies Inra
Hannrup, B.; Cahalan, C.; Chantre, G.; Grabner, M.; Karlsson, B.; Le Bayon, I.; Jones, G.L.; Müller, U.; Pereira, H.; Rodrigues, J.C.; Rosner, S.; Rozenberg, P.; Wilhelmsson, L.; Wimmer, R..
Genetic parameters were estimated for wood and growth traits in two 19-yr-old clonal trials and a 40-yr-old full-sib progeny trial of Norway spruce [Picea abies (L.) Karst.]. In the clonal trials high (>0.4) broad-sense heritabilities were found for wood density traits, lignin content, number of internal cracks, growth traits, spiral grain and number of resin canals. Moderate (0.2-0.4) heritabilities were found for tracheid lumen diameter and cell wall thickness, microfibril angle and tracheid length, while low heritabilities (<0.2) were found for pulp yield, fibre strength, wood stiffness and wood colour. Lignin content and pulp yield showed low genetic variation, whereas the genotypic coefficient of variation for most other traits ranged between 5...

Gesundheit und Leistungsfähigkeit von Milchkühen im ökologischen Landbau interdisziplinär betrachtet – eine (Interventions-) Studie zu Stoffwechselstörungen und Eutererkrankungen unter Berücksichtigung von Grundfuttererzeugung, Fütterungsmanagement und Tierhaltung Organic Eprints
Abograra, I.; Aulrich, K.; Barth, K.; Becker, M.; Berendonk, C.; Bormann, A.; Böhm, H.; Brinkmann, J.; Dittmann, L.; Drerup, C.; Haufe, H.; Harms, J.; Isselstein, J.; Klocke, D.; Klocke, P.; Knappstein, K.; Krömker, V.; Lange, G.; Leisen, E.; March, S.; Mersch, F.; Meyercordt, A.; Müller, J.; Müller, U.; Paduch, J.H.; Pries, M.; Rauch, P.; Ritter, S.; Sauerwein, H.; Schulz, F.; Schaub, D.; Schumacher, U.; Schuster, M.; Spiekers, H.; Südekum, K.H.; Sweers, W.; Tichter, A.; Volling, O.; Wendl, G.; Weiler, M.; Weiß, M.; Winckler, C.; Zinke, C..
Im Mittelpunkt des Projektes stand die Stoffwechsel- und Eutergesundheit von ökologisch gehaltenen Milchkühen im prä- und peripartalen Zeitraum sowie in den ersten 100 Laktationstagen und deren Beeinflussung durch die Futter- und Nährstoffversorgung und die Haltungsumwelt im umfassenden Sinn. In einer bundesweiten Feldstudie auf 106 ökologisch wirtschaftenden Milchviehbetrieben erfolgten Erhebungen mit dem Ziel einer Risikomodellierung zu Stoffwechsel- und Eutererkrankungen. Vor diesem Hintergrund wurden die Produktionssysteme von der Pflanzenzusammensetzung im Grünland und im Ackerfutter über die Grobfutterproduktion, Futterqualität und Rationsgestaltung, Haltungsumwelt bis hin zur Tiergesundheit und Milchqualität analysiert, um hier einzelbetriebliche...
