Agrophotovoltaik – Auswirkungen auf Mikroklima und landwirtschaftliche Erträge Organic Eprints
Weselek, Axel; Ehmann, Andrea; Zikeli, Sabine; Lewandowski, Iris; Högy, Petra.
Agrophotovoltaik (APV) ermöglicht die simultane Produktion von Nahrungsmitteln und Strom auf derselben Fläche, indem die Solarmodule etwa sechs Meter über der landwirtschaftlichen Fläche montiert sind. In der vorliegenden Studie wurden die Auswirkungen von APV auf die ökologische Produktion von Kleegras und Winterweizen sowie verschiedene mikroklimatische Parameter untersucht. Infolge veränderter mikroklimatischer Bedingungen und einer Reduktion der photosynthetisch aktiven Strahlung, kam es zu einer Abnahme der landwirtschaftlichen Erträge.

Bedeutung von Ackerbohnendichtsaat und Horngries für den Ertrag bei Brokkoli (Brassica oleracea convar. Botrytis var. italica) Organic Eprints
Veh, Christine; Graeff-Hönninger, Simone; Claupein, Wilhelm; Zikeli, Sabine; Ziehm, Nele.
Close seeding of field beans (Vicia faba) has been regarded for several years as an option in organic agriculture for the short-term introduction of nitrogen into production systems. At the same time faba bean potentially supplies nitrogen (N) to crops and soil by N2 fixation and nitrogen release when crop biomass is finally mulched. The main objective of this project was to investigate and develop a method of N-supply to meet the demand of broccoli using organic N-sources. Based on the results it can be stated that yield of broccoli significantly increased in the treatment intensive legume cropping plus fertilizer when compared to an intensive legume cropping without horngrist. However, upon inspection, it was revealed that marketable yields were even...

Der Anbau von Linsen und Erbsen im Gemenge Organic Eprints
Boland, E.; Zikeli, Sabine; Gruber, S..
In Germany, lentils (Lens culinaris) are traditionally grown in mixture with cereals to reduce lodging and weed pressure. To test semi-leafless pea (Pisum sativum) as an alternative companion crop instead of dwarf oat (Avena sativa), a field trial was conducted in 2015 at the organic research station of the University of Hohenheim, south-west Germany. The three crops were cultivated in pure stands and in ratios of 1:3, 1:1 and 3:1 (lentil : pea or oat). Focus was on comparing lodging resistance, weed suppression, and grain yield. Lodging was low in all mixtures but high in lentil pure stands. Yields were very high for lentils and peas but rather low for oats (3.2 t ha-1, 4.9 t ha-1, and 3.2 t ha-1, in pure stands). Similarly, high lentil yields were...

Entwicklung samenfester Brokkoli-Genotypen (Brassica oleracea convar. Botrytis var. Italica): Vergleich physikalischer und sensorischer Merkmalsausprägungen Organic Eprints
Sahamishirazi, S.; Frank, N; Zikeli, Sabine; Fleck, Michael; Claupein, Wilhelm; Graeff-Hönninger, Simone.
This study compared physical and sensory quality traits of three breeding lines and one hybrid of organic broccoli to find suitable open pollinating variety with high potential for marketability. An Instron texture analyzer was used to measure the firmness of the texture. Descriptive and hedonic tests were done to assess sensory quality. The evaluation of the genotypes by the panelists showed a trend to rank the lines as “good” in respect to their sensory properties and their outer appearance. CHE-MIC-31 was the firmest open pollinating genotype. Results of this study showed that this breeding line has the potential for marketability because of it’s superior physical and sensory attributes.

Entwicklung von Anbausystemen für Linsen im ökologischen Landbau Organic Eprints
Gruber, Sabine; Wang, Lina; Zikeli, Sabine; Mammel, Woldemar; Claupein, Wilhelm.
After commercial cropping of lentils (Lens culinaris) expired in Germany 50 years ago, a revival was observed on a small regional scale. Several field trials aimed at the development of lentil cropping systems to make lentils a more popular crop in German organic farming. One of the trials was set up to identify suitable companion crops and cropping ratios for lentils in mixed cropping systems. Suitable cropping systems in terms of yield (up to 1.8 t ha-1) were combinations with barley (Hordeum vulgare), wheat (Triticum aestivum) and buckwheat (Fagopyrum esculentum) in a ratio of 180 : 60 seeds ha-1 (lentil:companion crop), and with wheat or oats (Avena sativa, 1 : 3) in terms of lodging. As lentil and wheat grains were difficult to separate after harvest,...

Fertilizer value and nitrogen transfer efficiencies with clover-grass ley biomass based fertilizers Organic Eprints
Benke, Anna Pia; Rieps, Ann; Wollmann, Iris; Petrova, Ioana; Zikeli, Sabine; Möller, Kurt.
In temperate regions, legume-based green manures are a key element of organic rotations. However, specialized farms lack sufficient mobile organic fertilizers. To gain a better understanding of the N flows and the nitrogen (N) and phosphorus (P) fertilizer value of different clover-grass-based fertilizers (biogas digestate, compost, silage and fresh clover-grass obtained from clover grass ley biomass), we assessed their fertilizer value. Nitrogen and P offtake by the ryegrass was used to assess the shortterm effects. The data were completed using model calculations to assess the field-to-field N-transfer efficiencies and the overall N-transfer efficiencies. The greatest plant N offtake was achieved with digestates (64%) and the lowest from the compost...

Messung sekundärer Pflanzeninhaltsstoffe von Brokkoliblumen aus ökologischem Anbau Organic Eprints
Wolf, Stefanie; Fleck, Michael; Graeff-Hönninger, Simone; Zikeli, Sabine; Claupein, Wilhelm.
Today, consumer awareness on the healthiness of their foodstuff increases. The main focus is on secondary metabolites and antioxidants. Broccoli (Brassica oleracea L. convar. botrytis Alef. var. italica Plenck) has many compounds beneficial for human health, like Vitamin C, Carotionoids or Anthocyanins. To investigate these compounds two techniques are used in this study which are non-destructive sensor measurements (Multiplex®) to determine the value of anthocyanins (ANTH_RG) and flavonols (FLAV) and measurements of the antioxidant potential (water- (ACW) and lipid- (ACL) soluble antioxidants) on the basis of chemoluminescence. Field trials in autumn of 2011 and spring of 2012 were conducted in a randomized block design with different broccoli genotypes,...

Nährstoffmanagement in ökologisch bewirtschafteten Gewächshäusern in Südwest-Deutschland: Bedingt der Anbauverband die Düngestrategie? Organic Eprints
Zikeli, Sabine; Deil , Lucia; Möller, Kurt.
Ökoloogisch wirtschaftende Gartenbaubetriebe wirtschaften nutzen vor allem im geschützen Anbau oft große Mengen an externen Inputs als Grunddünger (Kompost oder Wirtschaftsdeünder) und Ergänzungsdünger (z.B. organische Handelsdünger wie Federmehle oder Produkte aus der Lebensmittelverarbeitung. Der Einsatz dieser Düngemittel ist über die EU-Ökoverordnung(834/2007 und 889/2008) geregelt. Bisher ist wenige über die Düngestrategien ökologischer Gartenbaubetriebe im Unterglasanbau bekannt, es fehlen beispielsweise Informationen zum Einfluss des Düngemamangements auf Nährstoffbilanzen und den Status an pflanzenverfügbaren Nährstoffen im Boden. Aus diesem Grunde wurden 10 ökologisch wirtschaftende Gartenbau in Südwest-Deutschland (5 Mitglieder von Bioland e.V....

Nitrat-, Betalain- und Zuckergehalte in vier verschiedenen samenfesten Rote Bete Sorten (Beta vulgaris L. ssp. vulgaris) im Vergleich zu einer F1 Hybride Organic Eprints
Yasaminshirazi, Khadijeh; Zikeli, Sabine; Fleck, Michael; Graeff-Hönninger, Simone.
Rote Beete (Beta vulgaris L. ssp. vulgaris) hat einen hohen Nährwert und gewinnt deshalb immer mehr an Bedeutung in der Lebensmittelindustrie, insbesondere zur Saftherstellung, Farbstoffgewinnung oder auch als vorgekochte Halbfertigware. In dieser Studie wurden vier samenfeste Sorten (Formanova, Bolivar, Robuschka und Ronjana) und eine F1-Hybridsorte (Boro F1) hinsichtlich ihrer Brixwerte, Nitrat- und Betalaingehalte miteinander verglichen. Im Jahr 2017 wurde hierzu auf der ökologisch bewirtschafteten Versuchsstation Kleinhohenheim der Universität Hohenheim (Stuttgart, Baden-Württemberg) ein Feldversuch als vollständig randomisierte Blockanlage angelegt. Obwohl die Ergebnisse zeigen, dass es signifikante Unterschiede zwischen den Sorten bezüglich der...

Open Pollinated Broccoli Genotypes: Agronomic Parameters and Sensory Attributes Organic Eprints
Wolf, Stefanie; Zikeli, Sabine; Fleck, Michael; Graeff-Hönninger, Simone; Claupein, Wilhelm.
Breeding of open pollinated (OP) varieties for organic farming gains further importance as varieties created by breeding techniques like CMS-hybridisation and cell fusion are no longer accepted by several organic farming associations. For broccoli (Brassica oleracea var. italica), the availability of OP varieties is very limited and the ones available are often not suitable for commercial crop production. In a participatory breeding project of the non-governmental, non-profit German association Kultursaat e.V. and the University of Hohenheim new genotypes were tested for agronomic parameters in field trials and sensory traits of cooked and raw broccoli were evaluated by two untrained consumer panels in 2012 and 2013. Agronomic traits of hybrids and OP...

Reduzierte Bodenbearbeitung im Biolandbau – Klimaaspekte Organic Eprints
Krauss, Maike; Perrochet, Frederic; Lori, Martina; Ruser, Reiner; Müller, Torsten; Zikeli, Sabine; Gruber, Sabine; Claupein, Wilhelm; Mäder, Paul; Gattinger, Andreas.
Die Umstellung vom Pflug auf eine reduzierte Bodenbearbeitung wird als Möglichkeit zur Minderung des Klimawandels im Zusammenhang mit einer erhöhten Humusanreicherung diskutiert. Ob reduzierte Bodenbearbeitungssysteme im biologischen Landbau zu einer erhöhten Lachgas-Entwicklung (N2O) führen, wurde bisher nur wenig beleuchtet. Im Langzeit-Bodenbearbeitungsversuch des FiBL in Frick wurden daher N2O-Emissionen über zwei Jahre hinweg und die Humusvorräte dreizehn Jahre nach Versuchsbeginn bis in eine Tiefe von 50 cm gemessen und mit weiteren mitteleuropäischen Studien verglichen. Die kürzlich publizierte Studie von Krauss et al. (2017) zeigt, dass es bei den N2O-Emissionen in der Weizen- und Kunstwiesenperiode keine Unterschiede zwischen den...

Screening von Senf-Genotypen zur Körnernutzung im ökologischen Anbau in Mitteleuropa Organic Eprints
Gruber, Sabine; Apukyia, Samuel; Zikeli, Sabine; Claupein, Wilhelm.
Information is rare about mustard (Sinapis alba, Brassica nigra, B. juncea) varieties and their characteristics for a suitable performance under organic conditions. 30 accessions were grown at the organic Research Station Kleinhohenheim in SW Germany in the year 2011. Highest grain yield was obtained by S. alba (10.5 g/plant) which was about four times the yield of B. nigra, and ten times the yield of B. juncea, mainly because of higher thousand kernel mass and high number of pods. B nigra and B. juncea were heavily damaged by pests so that only S. alba seems a suitable mustard species for German organic farming at the moment.

Stickstoffdüngewirkung und Stickstofftransfereffizienz von Düngemitteln auf Basis von Kleegrasbiomasse im Gefäßversuch mit Weidelgras (Lolium perenne) Organic Eprints
Benke, A.; Rieps, A.; Zikeli, Sabine; Möller, Kurt.
The aim of our research was to compare the N fertilizer value of different clover-grass (CG) based fertilizers. A pot trial was set up with 8 treatments with Lolium perenne: fresh CG, ensiled CG, compost from CG, solid manure and liquid manure from dairy cows fed with CG, biogas digestate, an unfertilized and a mineral fertilizer control. Our hypothesis was that compared to composting, and to other treatments (e.g. silage) biogas digestates allow for a more efficient N fertilization due to a lower C/N ratio and a higher share of NH4 +. Dry matter yield, C/N ratio, N concentration, N release and Nitrogen use efficiency (NUE) were examined. The results show the highest overall NUE, N release and yield in the treatment with biogas digestate and the lowest...

The challenge of imbalanced nutrient flows in organic farming systems: A study of Organic greenhouses in Southern Germany Organic Eprints
Zikeli, Sabine; Deil, Lucia; Möller, Kurt.
Organic greenhouse vegetable production is characterized by very high nutrient demands within short growing periods and high nutrient exports via products sold. Therefore, meeting crop nutrient demands and maintaining long-term sustainability in these systems is highly challenging. To gain insight in current practices this study assessed fertilization strategies and nutrient flows of ten organic horticultural farms (22 greenhouses and polytunnels) in Southwest Germany belonging to the two organic farming associations Bioland and Demeter (biodynamic) for a cropping period of three years. Soil samples were taken to analyze plant available phosphorus, potassium, soil organic carbon, pH and salinity. Crop rotations in the greenhouses were very diverse, though...

Die Dauer von der Pflanzung der Zucchinipflanze (Cucurbita pepo L.) bis zu deren Bildung der ersten pistillaten Blüte und schließlich Frucht variiert je nach Umwelt. In diesem Experiment wurden die Tage von der Pflanzung bis zum Beginn der ersten pistillaten Blüte sowie die Bildung der ersten Frucht von zwei verschiedenen Zucchini-Genotypen unter biologischen Anbaubedingungen ausgewertet. Die beiden Genotypen wurden zu drei verschiedenen Zeitpunkten (jeweils einen Monat auseinander) innerhalb einer Anbauphase gepflanzt. Die Gradwachstumstage (GDD) wurden berechnet, um mögliche Unterschiede zwischen den beiden Genotypen zu bewerten. Die erzielten Ergebnisse zeigten Unterschiede zwischen der erforderlichen Anzahl von Tagen und GDD nach dem Pflanzen bis zum...
