| Der Anbau von Feldgemüse stellt für Betriebe des Ökologischen Landbaus bei günstigen Standortvoraussetzungen eine wirtschaftlich interessante Option dar. Pflanzenbauliche Vorteile bestehen in der Auflockerung von Acker-Fruchtfolgen und in der günstigen Vorfruchtwirkung einiger Feldgemüsearten. Nachteilig sind die hohen Ansprüche an die Produktionstechnik und der hohe AK-Bedarf. Der humuszehrende Feldgemüsebau sollte zudem in eine ausreichend mit Humusmehrern, bspw. Kleegras gestaltete Fruchtfolge eingegliedert sein. Es werden die Grundlagen des Anbaus von Rosenkohl für das Produktionssystem mehrmalige Handernte dargestellt. |

| Biodynamic farming is the oldest organic farming movement in Germany. Since Dr. Rudolf Steiner’s “Course on Agriculture” held in 1924, the number of biodynamic farmers in Germany has grown continuously, with 1,317 farmers currently producing on 47,592 ha. One of the most distinctive aspects of biodynamic farming is the use of the so-called biodynamic preparations, which are applied in homeopathic doses. Biodynamic preparations are supposed to improve plant growth and food quality, minimising natural variations. This paper deals with investigations of influences of these preparations and increased manure application on potato yield and tuber quality. The results are drawn from extensive research on organic potato production carried out by several institutes... |

| The potential of ethanolic extracts of some common medicinal plants of Ethiopia for control of late blight (Phytophthora infestans) in tomatoes and potatoes has been investigated in vitro and in vivo. The application of several ethanolic plant extracts resulted in a significant inhibition of mycelium growth (0.25% m/v) and an impairment of late blight disease severity in vivo (1% m/v). Extracts from Hagenia abyssinica, Lepidium sativum and Lippia adoensis showed the strongest suppression of mycelium growth. The application of extracts derived from the H. abyssinica gave the highest in vivo bioactivity against P. infestans on tomatoes, but no effect was noted in potatoes under field conditions. The general potential of these extracts for late blight control... |

| Organic agriculture can and should play an important role in solving future challenges in producing food. The low level of external inputs combined with knowledge on sustainablity minimizes environmental contamination and can help to produce more food for more people without negatively impacting our environment. Organic agriculture not only includes farming as a production practice but it also includes processing, trade and consumption. Nevertheless, Organic agriculture must always evolve to overcome emerging challenges. Science-based knowledge attained through dedicated research is required to strengthen organic food and farming as a means to solve future challenges. In 2010, a global discussion about Organic 3.0 was initiated to address current problems... |

| In den Jahren 1995-1997 wurden an zwei Standorten Feldversuche mit Speisekartoffeln unter den Anbaubedingungen des Organischen Landbaus durchgeführt. Ziel der Untersuchungen war es, zu überprüfen, inwieweit sich der Ertrag und die Knollenqualität durch Variation der Anbaufaktoren Düngungshöhe (Rottemistgaben von 0 bis 240 kg Gesamt-N je ha), Düngungsart (organisch bzw. biologisch-dynamisch) und Sorte (Agria, Granola, Nicola, Provento) optimieren lassen. Wichtige Kenngrößen des Krautwachstums, des Knollenertrages und der Knollenqualität wurden ermittelt und einer varianz- und korrelationsanalytischen Auswertung unterzogen. |

| A competitive crop stand is a basis requirement for indirect weed control, potentially reducing the need for direct control measures. Efficient light interception by crop canopies can suppress weed growth by shading. As part of the EU-project ″Strategies of weed control in Organic Farming″ (WECOF) weed suppression by crop shading ability were evaluated in winter wheat. Three wheat cultivars with different leaf inclination and height (Greif, Astron, Pegassos) were grown at three row widths (12 cm, 17 cm and 24 cm) and two drilling directions (East-West, North-South) using a three-factorial design. Two field trials in 2000/01 and 2001/02, respectively, were conducted in Hennef, North-Rhine-Westphalia, Germany. No direct weed control measures were... |
