| 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... |

| Gerade im viehlosen ökologischen Landbau ist die Fruchtfolge eine der wichtigsten Einflussgrößen, die den pflanzenbaulichen Erfolg bestimmen. Als Stickstoffquelle stehen neben Kleegras auch vermarktungsfähige Leguminosen wie Soja zur Verfügung. Zwei der Fruchtfolgen des Dauerfruchtfolgeversuchs an zwei Standorten der Landesanstalt für Landwirtschaft lassen einen Vergleich zwischen Soja und einjährigem Kleegras in ihrer Wirkung auf die Nachfrüchte Winterweizen und Sommergerste zu. Die Erträge und auch die Qualitäten sind nach Soja signifikant niedriger als nach Kleegras, was die geringere Vorfruchtwirkung von Soja bestätigt. Betrachtet man dagegen die durchschnittlichen Fruchtfolgeerträge in Getreideeinheiten pro Jahr, liegen diese in beiden Fruchtfolgen... |

| The impact of seeding time was tested for hybrid rye in a yearlong field trial in Upper Bavaria. The rye (one variety) was seeded with the same sowing density at the end of September and at the mid of October, respectively. The impact of seeding time could be observed year-round: the mass growth before and after winter was obviously reduced by late sowing in comparison to usual seeding time. The results were lower plant height and clearly lower plant density in the variant late seeding time. Finally, the yield in the variant with usual seeding time was 27 % higher than by late sowing. Otherwise, the crude protein content, the falling number and the thousand seed weight were higher by late sowing. All in all, late sowing of hybrid rye may not be... |

| Über eine Symbiose mit Knöllchenbakterien sind Sojabohnen und Erbsen dazu in der Lage Stickstoff aus der Luft zu fixieren. Zur Höhe der N2-Fixierungsleistung gibt es bereits einige Untersuchungen, für Sojabohnen vorwiegend aus Übersee. Allerdings ist die N2-Fixierungsleistung von vielen Faktoren abhängig, wie z. B. Temperatur, Niederschlagsmenge und –verteilung, Sorte, Bakterienstamm, Nährstoffversorgung, Krankheits- und Schädlingsdruck. Daher war es ein Ziel des Projektes „Optimierung des Anbaus von Sojabohnen – Bestimmung des Vorfruchtwertes und der N2-Fixierungsleistung sowie Reduzierung der Bodenbearbeitung“, das von der Bundesanstalt für Landwirtschaft und Ernährung gefördert wurde, die N2-Fixierungsleistung unter den Bedingungen Süddeutschlands bei... |

| Die Sortenversuche zu Ackerbohnen wurden in Bayern auf zwei Standorten in 2010, 2012 und 2013 durchgeführt, wobei auf einem der beiden Standorte Anzeichen von Legumino-senmüdigkeit auftraten. Die Ergebnisse zeigten deutliche Unterschiede der Sorten in der Anfälligkeit für Fußkrankheiten auf, wie man an dem verschiedenen Sortenranking bezüglich des Kornertrages an den beiden Orten feststellen konnte. Die Sorten Julia und Herz Freya erreichten an beiden Standorten ein ähnliches Ertragsniveau, während für alle anderen Sorten der Ertrag auf dem Standort mit Leguminosenmüdigkeit deutlich abfiel. Hier erreichte Julia mit relativ 133 mit Abstand die Spitzenposition, während die Sorte auf dem anderen Standort einen durchschnittlichen Ertrag erzielte. Ursache war... |

| Zusammenfassung Die Studie zeigt die Ergebnisse einer Serie von Feldversuchen (2002-2006, zwei Orte, Südbayern, durchgeführt nach den Richtlinien des BSA 2000) auf vieharmen Biobetrieben mit Weißklee, Klee-Gras-Mischung, Rotklee und Gelbklee in Zwischenfruchtanbau als Untersaat. Ein Teil wurde in Frühjahrs- und Herbsteinsaat, ein Teil nur in Herbsteinsaat getestet. Zudem wurde ein Gemenge aus Weißem Senf und Sommerwicken in Stoppelsaat geprüft. Sämtliche Zwischenfrucht-Varianten entwickelten sich in allen Jahren und an allen Orten zufriedenstellend. Die Zwischenfrüchte - bis auf die Klee-Gras-Mischung im Herbstanbau – erhöhten die Korn- und Rohproteinerträge der Folgefrucht Hafer. Weißklee in Frühjahrssaat war die beste Untersaatvariante. Untersaaten von... |

| Cropping spring barley, long varieties with vigorous growth are desired in organic farming expecting better regulation of weeds. Six old varieties were compared to three modern varieties in a field trial during 2010 and 2011 nearby Freising, Bavaria. The modern varieties were the recommended varieties for Bavaria at beginning of the trial. Higher crop yields were determined for modern varieties with limitation for one of these varieties. The malt quality of the modern varieties was considerably better than for the old varieties. Vigorous growth and plant length was higher for all and for five of the six old in comparison to modern varieties, respectively. But no differences in weed pressure could be measured due to successful mechanical weed control.... |

| Erbsen und Ackerbohnen gelten als anfällig gegen verschiedene bodenbürtige Schaderreger. Das Verfahren der Biofumigation stellt eine Möglichkeit dar, den Schaderregerdruck im Boden zu begrenzen. Es wurde in Feldversuchen unter ökologischen und konventionellen Bedingungen geprüft, ob sowohl die Erträge als auch die agronomischen Eigenschaften dieser Körnerleguminosen positiv auf eine zur Biofumigation angebaute Zwischenfrucht reagieren. In einem von drei Versuchsjahren konnte ein Mehrertrag nach Sareptasenf im Vergleich zur Kontrollvariante bei Ackerbohnen und Erbsen im konventionell bewirtschafteten Versuch nachgewiesen werden. Bei den Futtererbsen brachten die beiden halbblattlosen Sorten Alvesta und Respect höhere Erträge nach Senf, wohingegen Protecta... |

| 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 seed source (conventional or organic farming) is one important question for the variety trials under the conditions of organic farming. Hence, field trials were conducted at two sites in Bavaria in two years (2013-2014). Certified organic seed from a Bavarian propagation were compared to conventional seed, offered by breeders for national variety trials. One until two varieties were examined for winter rye and for winter triticale in each year. Organic seed often showed higher crude protein content, conventional seed had mainly higher thousand seed weight and often superior germination power. The grain yield was mostly higher for conventionally produced seeds than for organic seed at one site, whereas seed source showed no differences with... |

| 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. |

| Achieving high baking quality and sufficient yield is often a challenge in organic wheat production. The impact of sowing date (either autumn or spring) was compared regarding grain yield, baking quality and infestation with chloropid gout fly of seven varieties of spring wheat. The field trial was conducted in 2010, 2012 and 2013 on a sandy loam nearby Freising, Bavaria. Two varieties showed higher grain yield after autumn sowing compared to spring sowing in two of the three years. But the opposite occurred consequently for two other varieties. The other three varieties showed no consistent reaction. This different reaction may refer in the majority to a different infestation with chloropid gout fly. Additionally, a higher baking quality (protein... |

| The cropping of leguminous cover crops usually leads to higher yields in subsequent cereals. The economic efficiency of leguminous cover crops was calculated in several field trials. Criterion was the yield (with adjusted costs) from the succeeding crops winter triticale and spring oats, respectively, after different leguminous cover crops undersown or as stubble seed in comparison to a control plot without cover crop. Thereby, the costs for seeds and the variable machine costs were taken into account. The highest yield was reached for both types of grain following undersown white clover, the second highest following undersown black medic. In contrast, the yield was lower following red clover and grass-clover undersowings as well as different stubble... |

| The risk of nitrogen leaching in winter after breaking of grass-clover sward can be reduced by delayed ploughing. The impact of ploughing date (either late autumn or spring) was compared regarding grain yield and baking quality of spring wheat. The field trial was conducted from 2001 to 2003 and from 2006 to 2008 on a trial site with sandy-loamy site conditions nearby Freising, Bavaria. Two varieties of spring wheat were examined. Higher baking quality (protein content, falling number, Zeleny index, wet gluten content, loaf volume) was identified in all years after ploughing in late autumn compared to spring ploughing. On the other hand, grain yield was higher after ploughing in spring in two of the six environments, but in one year the opposite... |

| Effective microorganisms (EM) were often applied in organic farming. The influence of three different compounds with EM (EM A, EM ceramic powder, Terra Biosa) was examined as compared with a control without application in a stationary field trial. The trial was conducted in 2004 – 2006 at Freising, Bavaria. Field beans, winter wheat and spring barley were grown. Higher crop yields in the variants with EM A and Terra Biosa application as well as higher crude protein content with EM ceramic powder application were determined compared to the control in each one of the three years. Susceptibility to diseases, resistance to lodging, thousand seed weight, sorting of grain yield and weed abundance were not affected by EM application. Taken into account the... |
