Beeinflusst die Bewirtschaftung das Vorkommen von Jakobskreuzkraut (Senecio jacobaea)? Organic Eprints
Suter, Matthias; Siegrist-Maag, Sandra; Luescher, Andreas.
Senecio jacobaea is a poisonous weed in grasslands of various countries (e.g. Great Britain, New Zealand, Central European states), and the further spread of the species into farmland must be prevented. Due to strong restrictions of curative measures, the prevention of S. jacobaea’s spread is of primary importance for organic farming. To assess the influence of management practice and site conditions on the occurrence of S. jacobaea, we conducted an on-farm survey in the northern and central part of Switzerland. Botanical assessments were carried out on grassland plots with S. jacobaea occurrence and on neighbour plots without S. jacobaea. For these plots, we analysed the soil nutrients and the details of management practice such as type and intensity of...

Managing docks with the WUZI dock cutter Organic Eprints
Laursen, Casper.
For each year that ploughing of a pasture is postponed, organic mat-ter in the soil can build up to 1000 kg N per hectare. Thus, the dock-cutter leads to a build-up of organic matter in the soil and effective termination of docks without ploughing. Practical recommendation • The mounting of the dock-cutter needs to be adjusted in order to fit a mini-loader or a front-loader on a tractor. In Denmark, mini-loaders are already present on many farms. • The docks are drilled by placing the drill on top of a dock and then using the oil pressure of the loader to turn on the cutter and terminate the dock. The cutter drills about 20 cm into the soil, which is enough to destroy the point of growth and thus prevent regrowth. • The dock-cutter automatically...

Fertilizer placement and competitive ability of spring barley varieties - Results from two years of organic field trials Organic Eprints
Madsen, K.H.; Bertelsen, I.; Askegaard, M..
Results from two years of field trial in organic spring barley showed a significantly higher grain yield per hectare in a competitive variety compared to a variety with lower competitive ability. Furthermore fertilizer placement resulted in a significantly higher grain yield than the broadcasted fertilizer application. The experiments furhermore, indicate, that combining fertilizer placement and growing a competitive spring barley variety will have mostly additive effect on the expected grain yield per hectare.

Monitoring der Deckungsgrade der Segetalflora auf Flächen des ökologischen Landbaus über einen Zeitraum von 10 Jahren Organic Eprints
Moos, Jan Hendrik; Paulsen, Hans Marten; Rahmann, Gerold.
The abundance of weeds was monitored on several permanent plots on an organically managed farm in Schleswig-Holstein, Germany. Variation in weed abundance was observed between plots. Neither general increase, nor general decrease in weed abundance could be identified. Most of the annual variations within the data could be explained by annual variation in precipitation. A more intensive view was on the abundance of Cirsium arvense and Galium aparine agg., two problematic weed species. While the known problems arising from the appearance of C. arvense could not be reflected in the used data, the data revealed possible problems through the partly high abundances of G. aparine agg

Pleveli kot bioindikatorji: vzorčenje in uporaba podatkov Organic Eprints
Carlesi, Stefano; Barberi, Paolo.
Članek opisuje uporabo plevelnih vrst kot indikator-jev stanja tal, ki je povezano ali z lastnostmi tal (kot sta pH ali tekstura tal) ali z gospodarjenjem s tlemi (zastajanje vode v tleh, premalo ali preveč hranil, zbitost). Poudariti je treba, da: (i) Tovrstna analiza ne zagotavlja vedno doslednih rezultatov. Odnos med različnimi plevelnimi vrstami in stanjem tal namreč ni vedno jasno začrtan. (ii) Za izvajanje te metode vzorčenja je potrebno nekaj osnovnega botaničnega znanja za identifikacijo plevelov.

Ertragswirksamkeit der Restverunkrautung in Gemüsekulturen nach nichtchemischen Unkrautregulationsmaßnahmen Organic Eprints
Laber, Hermann; Stützel, Hartmut.
Um Ertrags- und Qualitätseinbußen zu vermeiden, müssen Gemüsekulturen weitgehend unkrautfrei gehalten werden. Während im Zwischenreihenbereich dieses Ziel mit mechanischen Regulationsmaßnahmen durchaus erreicht werden kann, ist der Bekämpfungserfolg im Reihenbereich der Kulturpflanzen häufig unzureichend. Die hier verbleibenden Unkräuter können bei konkurrenzschwachen Kulturen zu hohen Ertragsausfällen führen. In den vorliegenden Untersuchungen wurden die Wirkungen der Verunkrautung, die nach thermischen und mechanischen Regulationsmaßnahmen in Möhren-, Zwiebel- und Blumenkohlbeständen verblieb, in Praxisbetrieben und, mit breiterer Variation der Verfahren, auf der Versuchsstation quantifiziert. Auf den Praxisbetrieben wurde das Ziel, unkrautbedingte...

Reduktion des Unkrautdruckes durch die Etablierung von Untersaaten in Mais-Bohnen-Gemengen Organic Eprints
Fischer, Jenny; Böhm, Herwart.
Am Thünen-Institut für Ökologischen Landbau (Schleswig-Holstein, sL, 740 mm, 8,7°C) werden von 2014-2016 Parzellenversuche zum Gemengeanbau von Mais mit Phaseolus-Bohnen durchgeführt. In vorangegangen Versuchen hat sich gezeigt, dass Mais und Bohnen infolge der langsamen Jugendentwicklung nur eine sehr geringe Konkurrenzkraft gegenüber Unkräutern aufweisen. Daher erfolgt die Aussaat der Bohnen erst nach Abschluss der mechanischen Unkrautbekämpfung mit Striegel und Hacke, zum 4-Blattstadium (BBCH 14) des Maises. Da mechanische Unkrautbekämpfungsmaßnahmen nach der Aussaat der Bohnen kaum durchgeführt werden können, wird in einem Untersaatenversuch geprüft, ob die Etablierung einer zusätzlichen Untersaat den Unkrautdruck im Gemenge nachhaltig reduzieren kann....

Maisanbau auf suboptimalen Standorten - Einfluss variierter Reihenweiten und Auswirkungen einer Dammkultur auf die Ertrags- und Qualitätsleistungen des Maises bei gleichzeitig variierter Beikrautregulierung Organic Eprints
Mücke, Markus; Meyercordt, Armin.
Zur Entwicklung geeigneter Anbau- und Beikrautregulierungsstrategien im Ökologischen Maisanbau auf Flussmarsch-Standorten sind drei verschiedene Anbauverfahren im Zeitraum von 2004 bis 2006 geprüft worden. Neben der Standard-Variante mit 75 cm Reihenabstand wurde eine Engsaat-Variante mit 37,5 cm und eine Dammkultur-Variante mit 75 cm Reihenabstand miteinander verglichen. Zur Beikrautregulierung kamen Standardgeräte wie Striegel, Schar- und Rollhacke sowie ein praxisübliches Häufelgerät aus dem Kartoffelanbau zum Einsatz. Im ersten Versuchsjahr 2004 wurde mit der Dammkultur neben einem deutlich verbesserten Pflanzenwachstum auch ein beachtlicher Mehrertrag von 30 % erzielt. Die Engsaat lag im Ertrag immerhin um 10 % über dem Standardanbauverfahren. In...

Aspekte zur Unkrautregulierung im ökologischen Landbau [Aspects for weed management in organic farming] Organic Eprints
Schleuß, Uwe.
Ein zentrales Problem im ökologischen Pflanzenbau ist es, die Schwierigkeiten bei der Regulierung der Unkrautflora in den Griff zu bekommen. Neben den direkten Verfahren der Unkrautregulierung (biologische, thermische oder mechanische Maßnahmen), kommen im ökologischen Landbau vor allem indirekten Maßnahmen eine besondere Bedeutung zu. Neben der Fruchtfolge sind weitere indirekte Unkrautregulierungsmaßnahmen, wie Lichtentzug, Saatgutreinigung, Saatgutqualität, Bodenbearbeitung, Standraum der Kulturpflanzen und Sorteneigenschaften zu nennen.

Douros, Nektarios; Angelopoulou, Fotini; Papastylianou, Panagiota; Papatheohari, Yolanda; Travlos, Ilias; Konstantas, Aris; Bilalis, Dimitrios.
Eastern purple coneflower [Echinacea purpurea (L.) Moench.] is globally recognized as one of the most popular medicinal herbs. In the present study, the effects of incorporation of the plant residues of this medicinal plant on weed flora and early growth of a sunflower crop were investigated. A field and a pot experiment were conducted at the Agricultural University of Athens. The field experiment was conducted under organic conditions, while in the pot experiment the focus was on the early growth of sunflower plants under the effect of plant residues. The results showed that there was a significant effect of plant residues on weed flora and the producted biomass, especially during the first crucial growth stages of sunflower. Particularly, the...

Åbent Hus: Forbedret udnyttelse af jord og ressourcer i økologiske dyrkningssystemer Organic Eprints
Kristensen, Helene.
Projektet SoilVeg handler om forbedret udnyttelse af jord og ressourcer i økologiske dyrkningssystemer for grøntsager med grønafgrøder. Der afprøves dyrkning af hvidkål i to nye dyrkningssystemer med reduceret jordbearbejdning. I det ene system plantes direkte ned i en tromlet vintergrønafgrøde uden anden jordbearbejdning, og her er det tanken at den tromlede biomasse dækker jorden og dermed holder ukrudt nede i løbet af sæsonen. I det andet system laves stribenedmuldning af grønafgrøden før plantning. De to nye systemer sammenlignes med almindelig nedmuldning og ingen forudgående grønafgrøde. Både vinterhestebønne, vinterært og vintervikke er blevet brugt som grønafgrøder og i blandinger med vinterrug. Disse forsøg kører ved Forskningscenter Årslev i 2016...

Seed mapping of sugar beet to guide weeding robots Organic Eprints
Griepentrog, Hans W.; Nørremark, Michael.
Individual plant care in agriculture will lead to new opportunities in crop management. Not only the weeding operation is in focus here but it will be more in general for individual chemical or physical treatments of individual weed or crop plants. For the application of fertilizers and chemicals in small dose rates and accurately targeted advanced sensor information e.g. based on spectral responses can be used to consider the individual plant needs ('the speaking plant'). This will have a significant effect on the reduction of inputs and increase the general efficiency rates of agricultural means. The objective of this project was to provide high accuracy seed position mapping of a field of sugar beet to allow subsequent physical weeding as inter- and...
