| 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.... |

| Zur Verbesserung der Anbauwürdigkeit der Blauen Lupine, insbesondere der Beikrautunterdrückung, wurde im Jahr 2017 in einem Feldversuch am Standort Hohenkammer bei Freising der Anbau im Gemenge mit verschiedenen Getreidearten und verschiedenen Saatstärken geprüft. Der Gesamtertrag war im Gemenge höher als in Lupinenreinsaat. Beide Getreidearten sowie beide Lupinensorten kombiniert mit Hafer zeigten im Gemenge höhere Rohproteingehalte als in Reinsaat. Die verzweigte Lupinensorte 'Boregine' war konkurrenz- und ertragsstärker als die endständige Sorte 'Boruta', Hafer war mit einem signifikant höheren Getreideertrag konkurrenzstärker als Weizen. Der Unkrautdruck war bei 'Boruta', aber nicht bei 'Boregine', im Gemenge signifikant geringer als in Reinsaat. |

| Der Anbau von Sommerkörnererbsen ist im Ökologischen Landbau häufig aufgrund einer geringen Beikrautunterdrückung und daraus resultierender Druschprobleme sowie spezifischen Pilzkrankheiten schwierig. Zusätzlich wird dieser Kultur oft eine mangelnde Wettbewerbsfähigkeit gegenüber anderen Produktionsverfahren attestiert. Als Folge wurde in den letzten Jahren der An-bauumfang in der landwirtschaftlichen Praxis deutlich reduziert. Einerseits ist im ökologischen Pflanzenbau neben einer schwierigen Beikrautregulierung die Stickstoffversorgung der Fruchtfolge einer der größten Problembereiche. An-dererseits besteht in der ökologischen Tierhaltung ein großer Bedarf an ei-weißreichen Futtermitteln. Daher wurde in Rein- und Gemengesaat mit Getreide die... |

| 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 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... |

| Blue lupin (Lupinus angustifolius L.) could be an additional local protein crop in Bavaria for animal and human food production. It would also enlarge crop rotation in organic agriculture. At the moment, this crop is mainly cultivated in the northeastern parts of Germany. It is adapted to pH until 6.8 and sandy loamy soils. Currently, it is not re-commended for cultivation in Bavaria. In field trials, different varieties of blue lupins proved to be worth cultivating on organically managed sandy loam and loamy sand on three sites in Bavaria. Boregine and Probor were tested for four years, Mirabor and Boruta for one year. All varieties showed high crop and protein yield, also compared to white lupins. Boregine had the highest crop yield, whereas Probor the... |

| In stockless organic farming, crop rotation is one of the most important factors that determine the success of crop cultivation. Six crop rotation schemes in a long-term experiment of the Bavarian State Research Center of Agriculture at Viehhausen allow the estimation of the effect of crop rotations on grain yield and baking quality of winter wheat. The three and five years crop rotations differed in the utilization of grass clover swards (cutting or mulching), in the following crops (potatoes or barley), in the portion of grass clover swards and in the type of legume (grass clover or grain legume).The lowest grain yield as well as the most inferior baking quality was shown after grain legume. The highest yield was obtained after the two-year grass-clover... |

| The preceding crop effect of fodder legumes concerning sowing date, type of legume and utilization were conducted in field trials at two sites in Upper Bavaria in 2012- 2013. All in all, seven types of clover in pure stands or clover/grass leys were grown one main production year. Sowing dates were undersowings in triticale in spring, stubble seeds after harvest of preceding crop triticale and spring seed in the main production year. Utilization variants were mulching or cutting without organic fertilization in the subsequent crop winter wheat. Mulching of fodder legumes resulted in higher yields and mostly higher baking quality (crude protein content, wet gluten content and baking volume) of the succeeding wheat. Earlier sowings leaded mostly to... |

| 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,... |

| 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... |

| 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 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... |
