| Winter peas have several agronomic advantages in comparison to spring pea, but the overwintering of winter peas are uncertain under the climatic conditions in Germany. Therefore, the winterhardiness of four genotypes (cvs. Assas, Cheyenne, EFB 33, Württembergische) was examined in two field trials in three growing seasons. In a first trial all peas were grown in pure and mixed stands with rye at the experimental farm of the University of Kassel and at the experimental farm of the University of Applied Sci-ence in Osnabrueck. In a second trial the impact of three sowing dates (mid of Sep-tember, end of September/begin of October and mid of October, respectively) was de-termined at the experimental farm of the University of Kassel only in pure stands. In... |

| Der Beitrag beschreibt Erhebungen zum Aufwand und Erfolg der mechanischen Beikrautregulierung im ökologischen Möhrenanbau, die über 3 Jahre auf 6 Praxisflächen in Sachsen und Niedersachsen zum Zweck des Vergleichs zu einem in der Entwicklung befindlichen Robotersystem (Projekt „RemoteFarming.1“) erhoben wurden. Die zeit- und kostenintensiven Beikrautregulierungsmaßnahmen die z.T. von Hand durchgeführt werden müssen, werden wegen des großen Einflusses des Beikrautbesatzes auf den Ertrag (Minderung bis zu 80%) in Kauf genommen. Die Anzahl Beikräuter schwankte sehr stark zwischen 7 bis 256 Pflanzen je Meter Möhrenreihe und es trat eine sehr große Varianz von 80-430 Jätestunden pro ha und Jahr auf. Zudem war der Regulierungserfolg stark von den einzelnen... |

| Beim Anbau von Sojabohnen (Glycine max (L.) Merr.) besteht während der langsamen Jugendentwicklung und der Abreife die Gefahr von Verbeikrautung, was in Ertragsreduktionen resultieren kann. Im ökologischen Anbau, in dem der Einsatz von Herbiziden nicht erlaubt ist, hat die mechanische Beikrautregulierung einen hohen Stellenwert. Zusätzlich werden häufig vorbeugende Maßnahmen, wie eine weite Fruchtfolge, eine enge Reihenweite und eine hohe Aussaatstärke angewandt. Dennoch besteht die Möglichkeit, dass diese Maßnahmen unter Umständen nicht ausreichenden Erfolg erzielen. Die Etablierung von Untersaaten kann durch Konkurrenz um Wachstumsressourcen zur Unterdrückung von Beikräutern beitragen, vor allem zum Zeitpunkt, wenn keine mechanische Beikrautregulierung... |

| Weed control in organic carrot production is time and cost intensive. There are several practicable techniques available for inter-row weed control, but the most sensitive area - ted by manual weeding. Weed regulation is usually done in uniform operations for one field, but weeds appear in a huge spatial variability, reflecting heterogeneous soil and climate conditions. Following the idea of precision farming, we developed a concept for camera-based weed detection, which displays the density as recommendation for velocity adaptation for the driver. The system was tested against the usual weeding with one constant velocity in a field trial with randomized plots. By using the new technology it was possible to increase the area performance by higher average... |

| Der pH-Wert ist ein relevanter Parameter für die Ertragsfähigkeit, auf dessen räumliche Variation zu reagieren ist. Der hohe Bodenuntersuchungsaufwand verhindert dies oft in der Praxis. Die mobile Sensorplattform MSP der Firma Veris Technologies Inc. ermöglicht eine räumlich hoch aufgelöste pH-Kartierung. In diesem Artikel wird die Einsatzfähigkeit dieses Systems für den Ökolandbau unter Praxisbedingungen geprüft. Eine effiziente Erstellung von Boden-pH-Karten ist grundsätzlich möglich. Allerdings sind weitere Untersuchungen zur Vergleichbarkeit der Ergebnisse mit der in Deutschland üblichen Methode notwendig und technische Modifikationen erforderlich, um einen störungsfreien Einsatz unter Praxisbedingungen sicherzustellen. |

| In organic farming, harvest of spring peas is a problem because of the often high density of weeds, but also the low yield stability. In the present experiments, seven different genotypes of winter peas (six regular types and one semi-leafless type) and one spring pea (semi-leafless) were examined between 2004 and 2007 in pure and mixed stands (with cereals) in terms of their suitability as a harvest crop at two different sites per season in Germany (experimental fields of the University of Kassel Frankenhausen (2004-2007), Hebenshausen (2004) and the experimental farm of the University of Applied Sciences Osnabrueck, Waldhof (2005-2007). Grain yields of the regular leaf type in mixed stands during the first three years varied because of varying N... |

| Die Arbeiten im Sojaforschungsprojekt waren erfolgreich und konnten wichtige Impulse für die Ausweitung des Sojaanbaus in Deutschland geben. So sind die entwickelten Stämme und Kreuzungsnachkommen eine Basis für den Aufbau einer eigenständigen deutschen Sojazüchtung. Die Sorten Korus und Protibus erwiesen sich als besonders geeignet für die Tofuherstellung. Die im Projekt entwickelte Labortofurei ist ein Züchtungsinstrument zur Identifikation vielversprechender Genotypen, mit dem auch die weitere Entwicklung frühreifer Tofusojasorten unterstützt werden kann. In Gefäßversuchen konnte gezeigt werden, dass die Reaktion auf Kühlestress während der Hülsenansatzphase zwischen den Sorten variiert und es tolerante, kompensierende und sensitive Sorten gibt.

| Examination of the effects of various earliness strategies on yield of soybeans In 2011 and 2012 a field experiment was realized in Osnabrück, Northern Germany, to study the influence of different earliness strategies on the yield of soybean. This study was done in a randomized strip design with four repetitions, realizing two earliness strategies, dissolving film and fleece cover, and additionally the control variant. In both years it was possible to increase the germination rate of the plants. Besides, there were no statistically significant differences between the yield of the three variants. However, in 2012, differences between the protein concentrations could be detected. The protein concentrations of the variants which were realized with... |

| The yield formation of the used varieties (Annabelle, Anuschka, Belana, Princess, Ditta, Allians) are closely related to their maturity groups. Some variety differences within the maturity groups do exist. Is the development of yield satisfying after a terminated harvest (a date between the 75. and 80. days after planting is suggested) and no more yield formation is expected then it is not necessary to spray some supplements against Late Blight. In case of an expected yield development the medium early varieties like Ditta or Allians are showing, it might be necessary to keep these plants healthy and decide to spray permitted supplements because their tuber bulking is later then the other chosen varieties. |

| In a three year research project a representative spectrum of coloured potato varieties were cultivated and tested in detail regarding yield potential and the influence of production systems (organic/integrated). The varying anthocyanin content as well as the antioxidant capacity of the types used were analysed to determine their potential health benefits. Types with a particularly high content undergo further tests to show the influence of the manner of preparation (boiling, steaming, frying) and determine their use for the processing industry. The cultivation of high yield blue types can be an alternative to the cultivation of yellow fleshed high yield types in organic or integrated operating farm companies. |

| Driven by an increasing demand for GMO-free soya as food or fodder, the production of organic Soybeans increases, also in high latitudes. As a legume crop, soya needs specific rhizobia bacteria to be supplied by biological nitrogen fixation (BNF). Since most soils lack the soy-specific strains, bacteria material is usually added manually. We set up a field trial with 5 site-years to investigate the benefit of this inoculation procedure in two different environments (humid, Germany/semi-arid, Russia) under organic farming conditions. Overall 5 different varieties were used (at each site 2 individual and 1 joint) to compare inoculation against untreated control. Leaf chlorophyll as indicator for BNF was determined by a SPAD-502. To make the SPADmeter... |

| A field experiment was conducted during the 2011 growing season to determine the effect of inoculation with Bradyrhizobium japonicum on yield, crude protein content (%) and nitrogen content of five inoculated and not -inoculated soybean varieties (Klaxon, Protina, Gallec, ES Mentor and Aveline). At three defined points of time (BBCH 23, BBCH 69, BBCH 75) plant samples including the root system were taken for analysis regarding the nitrogen content. Soil analysis to determine the N-min content had been carried out. Concluding the yield and crude protein content of the varieties was determined. Significant differences between inoculated and not inoculated varieties could be verified concerning yield, crude protein content and nitrogen content. |

| Walzen in Sojabohnen kann helfen die Ernte zu erleichtern. Um verzögerten Feldaufgang und Erosion zu verhindern wird in den USA/Kanada Walzen im 1-3 Blattstadium praktiziert als alternatives System zum Walzen im Vorauflauf. Dies hat den positiven Begleiteffekt, die generative Entwicklung (Hülsenansatz) durch den mechanischen Störreiz zu fördern. In einem Feldversuch wurde untersucht, wie sich die einzelnen Effekte auf Pflanzenentwicklung, Hülsenansatz, Beerntbarkeit und Ernteverluste in der Bilanz darstellen. |
