| Erkenntnisse aus 6 Versuchen ❯ Winterfuttererbse hat sich als Gründüngungspfl anze am besten bewährt, weil damit späte Aussaaten möglich sind ❯ Im Durchschnitt wiesen die Erbsen 156 kg Stickstoff pro ha in der Grünmasse auf ❯ Ohne zusätzliche N-Düngung erzielte der Silomais einen Ertrag von durchschnittlich 177 dt TS/ha ❯ In Ackerbaufruchtfolgen passt die Erbsen-Gründüngung gut, wenn nach Getreide eine Unkrautkur durchgeführt werden soll ❯ In Gemüsebaufruchtfolgen passen die Erbsen nach Lagerkulturen und vor Folgekulturen, die Ende Mai gepflanzt oder gesät werden ❯ Saatzeitpunkt: Anfangs Oktober (Überwinterung im 2-4 Blattstadium), Saaten bis in den Dezember möglich (Keimung Februar/März) ❯ Einarbeitung: Flaches Pflügen oder Scheibenegge... |

| In a field experiment three cultivation systems in organic onion production were compared: direct sowing, planting of set-onions and planting of seedlings with three to five seeds in each tray. The system with set-onions was the most efficient in terms of planting and sowing costs respectively and costs for manual weeding. The production costs of onions grown in the direct sowing system were 50 % higher than in the set-onion system. Directly sown onions have generally the best storage properties. Therefore this cultivation system may be an option if storability of the onions is important. The system with planted seedlings turned out to be the most expensive, hence it is only suited for special situations. |

| Preventative measures and the creation of resilient growing systems are key parts of pest management practice in organic field vegetable production (see also chapter 1). Soil improvement, crop rotation, site selection, habitat management, variety choice, timing of planting and plant spacing are all considered before planting in order to avoid the most detrimental pest problems. Due to the huge variety of vegetable crops and their associated pest insects, specific tailored approaches are necessary. The effects of cultural practices to reduce pest outbreaks, such as weed control, appropriate irrigation, suitable fertilization, the use of mulches, and adjusted harvest times have been investigated during the last few years. For some crops (e.g. cabbage and... |

| Im biologischen Zwiebelanbau ist der Aufwand für das manuelle Hacken und Jäten sehr hoch und daher oft ein limitierender Faktor. Die frühe Saat (oder Pflanzung) erschwert eine vorgängige Unkrautkur, wie das bei der Lagerkarotte z.B. gut möglich ist. Ein Ausweg dafür ist das Pflanzen der Zwiebeln, anstatt die Direktsaat. In dieser Arbeit wurde der Aufwand in den verschiedenen Zwiebelsystemen (Direktsaat, über Steckzwiebeln und Pflanzung) verglichen und nach Optimierungsmöglichkeiten innerhalb des jeweiligen Anbausystems gesucht. Insbesondere wurde geprüft ob mit einem Vlieseinsatz vor dem Abflammen, der Erfolg dieser Massnahme verbessert werden kann. |

| Powdery mildew attacks several important crops in greenhouses (e.g. tomatoes, cucumbers). Compared to other airborne pathogens, such as downy mildews (e.g. Pseudoperonospora cubensis or Phytophthora infestans) or Botrytis, the damage is often not very severe. However, an effective control of powdery mildew with organic fungicides gives the possibility to optimize climate conditions to also prevent downy mildews and gray mold. Sulphur, a well established fungicide, is rated as slightly to very harmful to beneficial organisms (Koppert Biological Systems, 2010) and may have a phytotoxic effect on some crops (e.g. melon). Effects of potassium and sodium bicarbonate (baking soda) against diseases are well known (Horst et al., 1992). In 2008, the European... |

| Der Biolandbau benötigt dringend angepasste Sorten. Die Biopflanzenzüchtung soll deshalb vorangetrieben werden. Ein Schritt in diese Richtung ist das Vernetzen der verschiedenen Akteure. An der ersten Biopflanzenzüchtungstagung am FiBL in Frick stand das Vorstellen der nationalen und europäischen Pflanzenzüchtungsprojekte im Vordergrund. |

| A transplant can be defined as a seedling or sprouted vegetative propagation material grown in a substrate or in the field, for transfer to the final cropping site. Nurseries use a range of growing media in the production of transplants, and the quality of a substrate may be defined in terms of its feasibility for the intended use and also according to the climatic condition of the production site. Peat is the worldwide standard substrate, but because of its origin and the increasing environmental and ecological concerns, new alternatives have been proposed for organic production. Here, we reviewed these new alternatives, assuming that the proposed growing media will need to respond in a proper way to specific plant requirements while also taking them into... |
