| In Fruchtfolgen im ökologischen Landbau wirken sich Unterschiede bei Anteil, Nutzung und Art der Leguminosen verschieden stark auf die nachfolgenden Marktfrüchte aus. Deren Erträge werden durch das Betriebssystem (viehhaltend oder viehlos) und die Position der Marktfrucht nach der Leguminose beeinflusst. Zur Untersuchung der Auswirkungen wurden seit 1998 im oberbayerischen Puch fünf verschiedene Fruchtfolgen angebaut und auf Ertrag und Produktivität geprüft. Bei der Produktivität zeigten sich deutliche Unterschiede, auch davon abhängig ob die Leguminosen in die Bewertung einbezogen wurden. Der ausschließliche Anbau von Marktfrüchten mit einer Körnerleguminose statt Kleegras führte zu deutlichen Mindererträgen der folgenden Marktfrüchte. Die höchste... |

| Die Wettbewerbsfähigkeit der für Süddeutschland typischen, bäuerlichen Ferkelerzeugung ist im ökologischen Landbau bisher gering. Dadurch besteht ein Umstellungshemmnis, das die weitere Entwicklung der Schweinhaltung im Ökolandbau behindert. Das vorgestellte interdisziplinäre Projekt soll mithilfe einer engen Zusammenarbeit von Forschung, Beratung und Praxis einen wesentlichen Beitrag zur Verbesserung der Produktionsbedingungen liefern. Ziel ist es, Grundlagen für eine Erhöhung von Leistung und Wertschöpfung in der ökologischen Ferkelerzeugung zu erarbeiten. Dies geschieht durch eine Verbesserung des Stands des Wissens über geeignete Haltungsverfahren, Stallbaulösungen, Arbeitsorganisation, Prozessqualität und Betriebswirtschaft. An dem Projekt sind sieben... |

| Die Intensivierung der Landwirtschaft hat zum Rückgang vieler Ackerwildpflanzen geführt. Der Ökologische Landbau bietet günstige Voraussetzungen für ihren Schutz. Wie entsprechende Populationen etabliert werden können, untersuchte ein Verbundprojekt der Bayerischen Landesanstalt für Landwirtschaft, der Technischen Universität München und der Universität Kassel. Die AG Freising untersuchte drei seltene winterannuelle Arten (Consolida regalis, Legousia speculumveneris, Lithospermum arvense) in mehrfaktoriellen Feldversuchen, in Praxisaus-saaten auf Bio-Betrieben sowie in Gewächshausexperimenten. Messgrößen waren Individuendichte, Samenproduktion und Bodensamenvorrat der Zielarten, zudem wurde der Ertrag der Feldfrüchte bestimmt. Frühe Herbstsaaten und... |

| Das Projekt „Entwicklung und Erprobung eines Agroforstsystems im ökologischen Landbau zur Energieholzgewinnung“ ist eine Kooperation der beiden bayerischen Landesanstalten für Landwirtschaft (LfL) und für Wald und Forstwirtschaft (LWF). Die Versuchsstandorte liegen in der nördlichen Münchener Ebene bei Freising und im südlichen Frankenjura in der Nähe von Kaisheim. Die zentrale Frage des Projektes ist, welche Erträge und Qualitäten die landwirtschaftlichen Feldfrüchte in einem Agroforstsystem im Vergleich zur herkömmlichen Bewirtschaftung ohne Bäume auf dem Acker liefern. Es wird eine positive Wirkung von Baumstreifen im Kurzumtrieb auf den Ertrag der dazwischen liegenden landwirtschaftlichen Kulturen erwartet. Außerdem wird untersucht, ob in einem... |

| The aim of this study was to evaluate the interaction between yield levels of nonleguminous crops and soil organic matter (SOM) under the specific conditions of organic and conventional farming, respectively, and to identify implications for SOM management in arable farming considering the farming system (organic vs. conventional). For that purpose, correlations between yield levels of nonlegume crops and actual SOM level (Corg, Nt, Chwe, Nhwe) as well as SOM-level development were examined including primary data from selected treatments of seven long-term field experiments in Germany and Switzerland. Yield levels of nonlegume crops were positively correlated with SOM levels, but the correlation was significant only under conditions of organic farming, and... |

| In organic crop rotations proportion, use and type of legumes have a different effect on subsequent crops. The yield of subsequent cash crops is affected by the farming system (livestock with organic fertilizer or stockless) and the temporal distance of the cash crop to the legume. To investigate the intermediate- and long-term effects on yield and productivity, a long-term field trial with six crop rotations was established in 1997 in Viehhausen, Upper Bavaria (one crop rotation with a period of 5 years, five crop rotations with 3 years). The present report tested these crop rotations regarding yield and productivity for the years 2000 to 2010. Significant differences were determined in productivity when legumes were included into the calculation. Crop... |

| The impact of a common and a reduced seeding rate on grain yield and quality for winter triticale was examined in four growing seasons at two experimental sites in Bavaria. Grain yield was lower for reduced seeding rate only in one of the four years in one environment. In that environment weed controlling was impossible because of high precipitation in autumn and spring. This was resulting in markedly higher weed coverage at reduced seeding rate due to a comparatively lower competitiveness. In all other environments no statistical differences in grain yields were determined because of higher 1000 K weight and higher tillering at reduced seeding rate. Fur-thermore, the crude protein content was higher for reduced seeding rate (9.4 and 8.9 % in DM,... |

| Leguminous cover crops are one important source of nitrogen in organic stockless farming. Therefore the influence of six legume species in pure stands and one grass-clover mixture on grain yield and quality of the undersown winter rye and of the succeeding crop spring oat was examined. Three field trials were conducted at one experimental site in southern Bavaria (2005/06/07 until 2007/08/09; in 2005/06/07 only three of six leguminous undersowings). Additionally, after the harvest of rye two stubble seeds (clover in pure and mixed stands with vetch and mustard) and a control (rye without cover crop) were established in each year. The cash crop was not affected by the undersown variants with respect to grain yield and quality. However, grain yield of the... |

| For stockless organic farming cultivation of leguminous cover crops is an important source for the nitrogen supply of organic cropping systems. However, too strongly developing living mulch systems may affect the undersown cash crop. At two experimental sites in Bavaria the impact of the sowing date of cover crops on grain yield of the undersown cash crop winter rye and the subsequent crop spring oat was determined in two and three field trials, respectively (2003/04/05 until 2004/05/06 and 2002/03/04 until 2004/05/06, respectively). Living mulch treatments were white clover and grass-clover (alfalfa, red and white clover, diverse grasses) with seeding in autumn and spring as well as red clover and black medick with seeding only in autumn. Additionally, a... |

| The productivity of seven soybean cultivars was examined at two experimental farms in Upper Bavaria during three growing seasons. Highest grain and crude protein yields were determined for the cultivar Merlin (maturity group 000), whereas other varieties of the same maturity group and the high protein cultivars Primus and Lotus obtained considerably lower yields. Harvest date for soybeans of maturity group 000 was usually in the mid of September. In five of six environments 000 cultivars harvested in average 16 days earlier than varieties of lower maturity groups. Expectably highest crude protein contents were analysed for Lotus and Primus. |

| Intensive land use has led to a drastic decline of arable weeds in Central Europe. The objective of the project “Restoration of local populations of rare and endangered arable field plants on organic farms in Germany” is to develop methods for a successful re-establishment of arable weeds on fields where absence of herbicides provides favourable development conditions. Two complementary approaches are tested by research teams at Freising and Witzenhausen. In Freising two exact trials were set up in order to find suitable crops and dates for the initial sowing of three rare and endangered species (Consolida regalis, Legousia speculum-veneris, Lithospermum arvense). The study area is located in the Munich Plain which is characterized by limestone gravel.... |

| Es werden Zwischenergebnisse aus den Jahren 2003 bis 2005 einer bis 2007 laufenden Versuchsserie von zwei Versuchsorten (Tertiäres Hügelland, Bayern) dargestellt. Geprüft wurde die Wirkung von Zwischenfrüchten auf die Deckfrucht Winterweizen und die Folgefrucht Wintertriticale. Alle geprüften Arten - Gelbklee, Hornschotenklee, Rotklee, Weißklee - und eine Feldfutterbaumischung zeigten sich als tauglich für Untersaaten. Es bestanden Unterschiede im Wuchsverhalten und in der Aufwuchsleistung. Diese schwankte von ca. 1,0 dt/ha Trockenmasse (TM) im sommertrockenen Jahr 2003 bis ca. 20,0 dt/ha TM im Sommer 2004. Die Zwischenfrüchte zeigten - im Vergleich zur Variante „ohne Untersaat = Selbstbe-grünung“ - auf die Kornerträge der Deckfrucht Winterweizen keine... |

| So far there is only little experience with the cultivation of coppicing fast-growing tree species in German organic agriculture. The research project investigated the establishment and the performance of different tree species - black alder (Alnus glutinosa), grey alder (Alnus incana) and two hybrid poplar clones ('Max 1', 'Max 3') under organic conditions. Various strategies to reduce weed competition were examined. Different undersown crops (Medicago lupulina, Trifolium repens, Camelina sativa, Secale cereale) and a self-degradable mulch membrane were compared with an untreated control. The two experimental sites are located in Southern Bavaria (Germany). All tree species could be successfully established on both experimental sites. The results show... |

| Due to recent intensification of land use the arable flora is considered to belong to the most threatened groups of plants in Europe. Therefore, the objective of the project ‘re-introduction of rare arable plants on organic farms in Germany’ is to develop methods for a successful re-establishment of arable plants on fields with favourable management conditions. The present study describes the effects of different cover crops and crop rotations on the establishment of three endangered species (Consolida regalis, Legousia speculum-veneris, Lithospermum arvense) in a field experiment at Gräfelfing close to Munich. Results from the first 3 years indicate that successful establishment mainly depends on crop competition during the 1st year. As individual species... |
