| 1. Feldversuche Die Winterweizensorten Arina und Capo wurden im Versuchsjahr 2002/2003 auf insgesamt 12 Standorten im Ökologischen Anbau als Reinbestände und als Sortenmischung angebaut. Das Versuchsjahr war extrem trocken, weshalb kein relevanter Krankheitsbefall zu verzeichnen war. Die Erträge variierten je nach Standort von 26 bis 53 dt/ha wobei Capo deutlich ertragsstärker war als Arina. Die Mischung brachte im Schnitt 3% mehr Ertrag als erwartet und war im Ertrag deutlich stabiler. Dies war auf die stärkere Konkurrenzkraft der Sorte Capo an fast allen Standorten zurückzuführen. Arina übertraf Capo signifikant im Rohprotein (RP) (12.9 versus 12.2%) und Feuchtklebergehalt (FK) (29.8 versus 25.3%), was auch im Backvolumen reflektiert wurde. Während bei... |

| The UK organic wheat crop, of about 15,000 hectares, is rarely able to consistently provide flour of suitable quality to meet the needs of the baking industry. As a result, more than 50% of the requirement for wheat in the organic bread market is imported. This project seeks to address the constraints to the expansion of the market for organic bread produced from wheat grown in the UK. This will be achieved by identifying the effect of agronomic practices on the protein content and quality of organic wheat. The work will optimise the interaction of raw material characteristics with formulation and processing approaches on bread quality. This will be achieved by establishing the effects of varieties and nitrogen applications in crop husbandry practices on... |

| The performance of UK winter wheat varieties was tested under organic conditions involving farmer participation. Three breadmaking varieties (Hereward, Solstice and Xi19) and their mixture (1:1:1) were grown at 19 UK farms in 2003/04 and 2004/05. The variability of productivity on organic farms was illustrated with more variation among farm sites than among varieties. Seed health was generally high over all sites. Although the trials were successful, more time was needed at project initiation to improve farmer involvement. Some farmers expected more researcher visits, and were reticent about assessing the trials themselves. In contrast, some participants valued the variety performance data on their farms particularly when related to that of other growers.... |

| The aim of the project is to use an ecological approach to analyse the interactions of a range of key agronomic variables in organic wheat production (wheat genotype, spatial arrangement of seed, seed density and wheat/white clover bi-cropping) to determine an optimal approach to improved and stabilised production. The fi rst set of data revealed that seedling competition was infl uenced by seed rate and drilling arrangement. Furthermore, the variety Hereward had increased emergence and establishment to Aristos. An interaction exists between wheat variety, seed rate and drilling arrangement on the level of canopy cover at different developmental stages – these factors are important for the suppression of weeds. The input of farmers in the selection of... |

| Consumers have become more aware of healthy and safe food produced with low environmental impact. We studied the quality of wheat (Triticum aestivum L., winter form) grown in a 21-year agro-system comparison between organic and conventional farming in Central Europe, known as the DOK experiment. The 71% lower addition by plant available nitrogen to the organic field plots led to 14% lower wheat yields. However, the nutritional value, i.e. protein content and baking quality, were hardly affected by the farming systems. Despite exclusion of fungicides from the organic production systems, the quantities of mycotoxins detected in wheat grains did not differ. Food preference tests, as an integrative method, indicated a tendency for rats to prefer organically... |

| Für die Ergebnisse der vorliegenden Untersuchung wurden Winterweizenproben aus der biologisch-dynamische (23 Proben der Sorte Rektor, 8 Proben Bussard) und konventionellen Praxis (je 10 Proben der Sorten Rektor, Bussard und Astron) des Erntejahres 1996 untersucht. ► Der mittlere Rohproteingehalt der konventionellen Proben betrug 13,4%, was dem langjährigen Mittelwert entspricht. Die biologisch-dynamischen Proben deckten N-Gehalte zwischen 1,4 und 2,2% ab. Ihr mittlerer Rohproteingehalt betrug 9,8% und lag damit noch etwas niedriger als der Wert von 10,0% von Proben des Erntejahres 1995. ► Die biologisch-dynamischen Proben wiesen bedeutend niedrigere Schwefelgehalte (Mittelwert = 0,12%) als die konventionellen Proben auf (Mittelwert = 0,15%), was auf der... |

| Das Projekt befasste sich mit einem Sortenscreening von 23 Lupinus albus-, 14 L. luteus- und 21 L. angustifolius-Sorten auf die Reaktion gegenüber einer Infektion mit Colletotrichum lupini var. setosum. Für die Infektion der Samen wurde der Substrattest, eine Methode, die die Primärinfektion des Pathogens simuliert, genutzt. Der Einfluß der Infektion auf verschiedene Merkmale, wie Überlebensrate der Pflanzen, Symptome, Befallsverlauf und auf den Ertrag wurden bewertet. Die drei Lupinenarten zeigten unterschiedliche Krankheitssymptome. Während die Symptome bei L. luteus und L.angustifolius oft untypisch waren, entwickelten sich bei L. albus bekanntere Anthraknosesymptome. Unterschiedliche Verhaltensweisen der drei Lupinenarten waren auch im Befallsverlauf... |

| Agricultural advantages of mixed cropping are gained from biological effects like light competition offering weed-suppressing capacities, or by diversification of plant covers to break development cycles of pests. These effects were measured in a two-year project on mixed cropping with organic oilseed crops. It was found that weeds can be efficiently suppressed in organic linseed (Linum usitatissivum) grown in combination with wheat (Triticum aestivum) or false flax (Camelina sativa). Linseed growth was, however, impaired. In organic pea production (Pisum sativum) also, growing the crop as a mixture with false flax led to a significant decrease of weed population. Either culture showed a balanced plant development. In winter rape (Brassica napus) there... |

| Disease development, yield and baking quality were assessed on the winter wheat cultivars Arina and Capo and their 1:1 mixture in a total of 12 sites on-farm in 2002/2003. Due to a severe drought disease severities were very low and probably had little effect on the plants. The more drought tolerant variety Capo over-yielded in mixtures on average by 21% while Arina yielded in mixtures as expected. Protein and gluten contents and baking volume in pure stands of Arina were usually higher than for Capo. Both varieties changed their quality parameters in mixtures. However, the parameters of the mixtures were not equal to the mean of the pure stands indicating some unknown interactions. The quality parameters of each variety or mixture were compared to the... |

| Der Erbsenwickler, Cydia nigricana (Lep.: Tortricidae), hat sich in den letzten Jahren zum Problemschädling in Körnererbsen entwickelt. Als vielversprechender Regulierungsansatz wurde in der Feldsaison 2000 das Sexual-Pheromon des Erbsenwicklers mit der sog. "Verwirrungstechnik" erstmalig in Deutschland eingesetzt. Ziel dieses ersten Probelaufs war es, grundsätzliche technische Erfahrungen bezüglich Ausbringung, Dispenserbeladung, Flächendosis udn Abdampfrate zu sammeln und die für Wicklermännchen beschriebenen charakteristischen Verhaltensänderungen infolge Pheromoneinfluss zu reproduzieren. In dem dargestellten Probelauf konnte die grundsätzliche Eignung sowohl der eingesetzten Pheromonqualität als auch des gewählten Dispensers demonstriert werden.... |

| Selection of cereal varieties suited to organic farming requires a different, but complementary, approach to that used when developing cereals for conventional high input systems. Selection is based on the interaction between a series of desirable plant and crop characteristics, in particular competitive ability against weeds. Certain key characteristics that are generically desirable for organic cereal varieties include: (1 good establishment ability, (2) high tillering ability, (3) increasing plant height, (4) planophile leaf habit, (5) high leaf index and (6) robustnesses in yield performance across sites. Our data strongly suggest that high crop ground cover is the most important feature for creating a highly competitive crop that also has consistency... |
