| 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... |

| Der Versuchsbetrieb Mapraz wurde gegründet, um Fragen zu beantworten, wenn Betriebe auf viehlosen Bio-Ackerbau umstellen wollen. Nach zwölf Beobachtungsjahren, in denen in den sechs letzten Jahren zwei Fruchtfolgen verglichen wurden (mit einem Jahr oder zwei Jahren Kunstwiese - KW), sind die durchschnittlichen Erträge beim in Weizen um 8% tiefer als die Richtwerte oder vergleichbar mit den Bio-Richtwerten bei der Ackerbohne und beim Hafer. Die Deckungsbeiträge liegen zwischen CHF 250 und CHF 670/ha unter den Richtwerten der Bio-Landwirtschaft mit Vieh. Die Fruchtfolge mit zwei Jahren KW zeigt einen besseren Deckungsbeitrag (CHF 200/ha) und benötigt weniger Arbeit (-2 Std./ha) als die Fruchtfolge mit einem Jahr KW. Die Ackerkratzdistel konnte mit der... |

| This is the final report for Defra Project OF0159. The Organic Conversion Planner (OrgPlan) is a computer program for farmers and advisors reducing the time input necessary for planning a conversion to organic farming. Conversion planning can help to identify whether organic management is suited to the farm and potential problems during the conversion period itself. This involves an assessment of the current situation of the farm, based on which proposals for an organic 'target (endpoint)' can be developed. This includes proposed rotation(s), cropping and stocking plan for the specific farm situation and the proposals need to be tested for their technical and financial feasibility, including impact on forage supply, nutrient requirements and financial... |

| Grain legumes benefit the farming system via symbiotic N2 fixation and subsequent residue incorporation contributing to soil fertility together with their effect as break-crop in cereal rich rotations. However, grain legumes are weak competitors towards weeds and consequently weeds constitute a major problem. Since the European policies for reducing the negative effects of agricultural plant production on the environment point to reductions in pesticide use (Mortensen et al., 2000), there is a requirement to further develop strategies to reduce weeds. Intercropping involves the simultaneous growing of several plant species in the same field and the cropping strategy is known to involve interspecific interferences increasing the use of plant growth... |

| Selenium (Se) and glucosinolates has been found to have beneficial effects for human health. The most common way to increase Se and glucosinolates in plants is through using inorganic fertilizers however, concerns over environmental contamination by fertilizers increased the demand for sustainable produced foods. Thus, the aim of this project was to evaluate the efficiency of different crop management strategies (catch crops, intercropping) to increase Se and glucosinolates concentrations in plants rather than the application of agrochemicals. Catch crops have been used successfully to reduce sulphur and nitrogen leaching and increase nutrient availability for the succeeding, similar beneficial effects on Se may be expected. Nitrogen and sulphur... |

| In many countries, cotton is traditionally intercropped with other plants in order to increase yields and to control pests. We tested the effects of intercropping cotton (Gossypium barbadense L.) and basil (Ocimum basilicum L.) during one field season on pest infestation, yields, and economical parameters in the Governorate of Fayoum, Egypt. Basil, which is known for its repellent effect on various insect pests, was mixed with cotton in three different intercropping rates (no, medium and high basil area fraction) and two row distances (60 and 90 cm) using a substitutive design with four replicates. Compared with the non-intercropped plots, cotton-basil intercropping significantly reduced total pest infestation and led to a 50% reduced abundance of the pink... |

| O objetivo deste trabalho foi avaliar o efeito da terra de diatomáceas sobre a incidência de tripes e a produtividade e o peso médio de bulbos em cebola no sistema orgânico. O trabalho foi conduzido entre agosto e dezembro de 2004 e de 2006. Em 2004, os tratamentos constaram de pulverização de terra de diatomáceas a 1% , 2% e 3% , e testemunha sem aplicação. Em 2006 usou-se terra de diatomáceas pulverizada a 0,5% e 1% , e em aplicação no sulco de plantio, nas dos e s de 40 k g/h a aos 30 dias após transplante (DAT) e 45 DAT;60 k g/h a aos 30 e 45 DAT;20 k g/h a aos 30 e 45 DAT;30 k g/h a aos 30 e 45 DAT, e testemunha sem aplicação.

| A four year experiment is being carried out, at Ege University Department of Horticulture, in which three different pre-crops are tested under an organic management system as compared to fallow. The aim of the experiment is to identify the most suitable rotation program for organic vegetable production in Turkey. Vicia sativa (common vetch), Brassica oleracea var. italica (broccoli), Vicia faba ‘Sevilla’ (faba bean) and fallow are tested as preceding (winter) crops. During the experiment carried out between 2007 and 2009, the main crops were tomato (2007), zucchini (2008) and pepper (2009). Broccoli represented the farmers’ choice as a winter vegetable. Vetch (incorporated) and faba bean (partially harvested and incorporated) were selected as legumes well... |

| 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.... |

| 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... |

| European agriculture focuses on increasing biodiversity. However, in highly productive temporary grasslands in grass / arable systems, the biodiversity is usually low. Three non-leguminous species have shown high competitive strength in temporary grasslands and ample possibility to increase biodiversity without compromising yields. In this experiment, we examined in detail the competitiveness and productivity of the three forb species: chicory (Cichorium intybus), ribwort plantain (Plantago lanceolata) and caraway (Carum carvi) grown in different proportions in mixtures including traditional grassland species: perennial ryegrass (Lolium perenne) and red clover (Trifolium pratense), with fertiliser application as an additional factor. Dry matter (DM) yield... |
