| Auf dem Modellbetrieb für Ökolandbau in Müncheberg wurden von 1993 bis 2013 Feldversuche zur Ermittlung der Ertragsstabilität von zwei Körnerleguminosen (Schmalblättrige Lupine und Futtererbse), Wintergetreide (Roggen und Weizen), Hafer und Silomais durchgeführt. Zwei orthogonale Datensätze wurden genutzt um die temporären Ertragsschwankungen der Einzelkulturen zu vergleichen. Beide Körnerleguminosen zeigten die geringste Ertragsstabilität von allen untersuchten Kulturen. Dies war sowohl für varianzbasierte als auch für regressionsbasierte Stabilitätsparameter der Fall. Gründe für die geringe Ertragsstabilität sind unzureichend bekannt. Es müssen Strategien für das Management entwickelt werden, um mit den großen Schwankungen umzugehen. |

| The inter-relationship between food production and biodiversity is now well established. The ecosystem services provided by the organisms within the environment include, for example, nutrient cycling, pest regulation and pollination, to name but a few. However, perhaps the greatest challenge now facing agricultural production is to find ways of enhancing these ecosystem services, while at the same time increasing food production – particularly in light of food security issues. A range of farm and landscape management options include ‘setting aside’ land for wildlife. However, some proponents argue that such land should be used for food production. While the debate continues, there is no doubt that a large body of scientific evidence from the last three... |

| An Organic Research Centre project is examining how diversity-based tools can assist in the on-farm improvement of organic wheat. Successful organic crop production requires varieties that are resistant to diseases, competitive against weeds, and effective at scavenging nutrients. Yet conventional plant breeding has largely neglected organic systems by breeding varieties exclusively for high input conditions. As a consequence, organic producers currently do not have enough choice of plant varieties for organic conditions. One way to expand the choice is to create plant diversity anew and subject it to natural selection on organic farms. After several generations the dominating plants would be better suited to organic systems. This idea is being tested... |

| In Praxisversuchen wurde über drei Jahre der Einfluss von Strohmulch auf das Auftreten von PVY (Potato virus Y), den Befall mit dem Kartoffelkäfer (Leptinotarsa decemlineata) und den Knollenertrag in ökologisch angebauten Kartoffeln untersucht. Strohmulch führte in drei von 17 Experimenten zu einer signifikanten Reduktion von PVY, und in weiteren sieben Versuchen gab es einen nicht-signifikanten Trend zur erminderung von PVY. Der Effekt von Strohmulch auf PVY scheint vom allgemeinen Infektionsniveau abzuhängen, welches je nach Jahr, Standort und Sorte unterschiedlich war. So gab es in den Jahren 2002 und 2004 bei allgemein hohem Infektionsdruck eine konsistente PVY-Verminderung. Im Gegensatz dazu konnte im Jahr 2003, bei nur sehr geringem Infektionsdruck,... |

| Die Anwendung von Strohmulch als eine mögliche Strategie zur Reduzierung von Bodenerosion, Virusinfektionen und Nachernte-Stickstoffverlusten in Kartoffeln wurde hinsichtlich der Effekte auf die Krautfäule (Phytophthora infestans [MONT.] DE BARY) und auf die Pockenkrankheit (Rhizoctonia solani KÜHN) in ökologisch geführten Feldexperimenten über drei Jahre an vier Standorten in Deutschland untersucht. Der Krautfäulebefall wurde in 15 Versuchen als Prozent befallener Blattfläche oder Prozent der Blätter mit Läsionen bonitiert. Rhizoctonia-Pocken auf den geernteten Knollen wurden bei 100 bis 220 Knollen pro Parzelle in 18 Feldversuchen bonitiert. Zusätzlich wurde in einem Feldversuch der Einfluss von Strohmulch auf die Lufttemperatur und die relative... |

| Agroforestry is a land-use system that integrates trees and shrubs with crops and/or livestock production. It has been identified by the International Assessment of Agricultural Knowledge, Science and Technology for Development (IAASTD, 2008) as a ‘win-win’ approach that balances the production of commodities (food, feed, fuel, fibre, etc.) with non-commodity outputs such as environmental protection and cultural and landscape amenities. This paper will review the potential of agroforestry as part of a multifunctional working landscape in temperate regions, and will consider management and policy implications of widespread adoption of this form of land-use. |

| As part of the TILMAN-ORG CORE ORGANIC II project, data on the use of reduced tillage in organic farming systems from a range of field trials and the published literature was compiled. A meta-analysis was conducted to determine the impacts of reduced tillage on crop yields, weed pressure and soil organic C stocks. This paper highlights some of the key findings from this study. |

| The application of straw mulch to organic seed potatoes (Solanum tuberosum L.) has been shown to reduce virus incidence. In order to determine the associated agronomic effects of straw mulch, applied at 2.5–5 t ha�1, on soil nitrate dynamics, weed development, tuber yield and soil erosion, 12 field experiments were evaluated. Experiments were conducted on organic farms over 3 years at two locations in a temperate climate (635–709 mm precipitation/year; 8.1 8C mean air temperature) on loamy silt soils. Tuber yield and tuber size distribution were not influenced significantly by mulching. However, the risk of undesirable post harvest N-leaching was significantly reduced due to the immobilization of nitrate–N after harvest at 6.8–7.0 kg N t-1 straw in two... |

| Despite the importance of yield stability in organic agriculture, little quantitative information is currently available on the factors limiting stability or on optimal approaches for improving it. Research so far indicates that organic systems are not always more stable than conventional systems; which system is more stable is likely to depend on the spatial and temporal scale of stability and on the measure of stability used. We show that opportunities for quantifying yield stability in organic farming lie in the targeted coordination of existing data networks within the organic community in order to increase yield stability on farms and beyond. |

| There has been a remarkable scientific output on the topic of how climate change is likely to affect plant diseases in the coming decades. This review addresses the need for review of this burgeoning literature by summarizing opinions of previous reviews and trends in recent studies on the impacts of climate change on plant health. Sudden Oak Death is used as an introductory case study: Californian forests could become even more susceptible to this emerging plant disease, if spring precipitations will be accompanied by warmer temperatures, although climate shifts may also affect the current synchronicity between host cambium activity and pathogen colonization rate. A summary of observed and predicted climate changes, as well as of direct effects of climate... |

| As costs for mineral fertilizers rise, legume-based leys are recognised as a potential alternative nitrogen source for crops. Here we demonstrate that including species-rich legume-based leys in the rotation helps to maximize synergies between agricultural productivity and other ecosystem services. By using functionally diverse plant species mixtures these services can be optimised and fine-tuned to regional and farm-specific needs. Field experiments run over three years at multiple locations showed that the stability of ley performance was greater in multi-species mixtures than in legume monocultures. In addition, mixing different legume species in the ley helps to suppress both early and late weeds. Further, combining complementary phenologies of... |

| Legume-based leys offer multiple benefits to ecosystem service provision, e.g. protecting soil and supporting pollinators. While weeds can play an antagonistic role during ley establishment, little is known about weed communities in these leys or about the optimal solutions for weed control in the establishment phase. To determine if the choice of ley species affects weed levels, we conducted field trials at six locations in the UK, measuring weed cover and biomass in monoculture plots of 12 legume and 4 grass species, plus an all species mix over two years. In these trials and in additional on-farm trials, weed cover and diversity were lower in the second than in the first year, owing to a decrease of annual weeds over time. The ability of a diverse... |

| The ability of different legume cover crops to suppress annual weeds during the early establishment phase was compared using a simulation model of inter-plant competition and field observations. Height, partitioning parameters, extinction coefficients, crop density and time of emergence were recorded for 11 species sown in monocultures. A naturally occurring population of fat hen (Chenopodium album) was present on the experiment. The competition model was run to compare the expected suppressive ability of the different species on this weed. Samples of C. album were also taken from each plot immediately prior to cutting to provide some empirical observations. Predicted suppressive ability was correlated with seed size and height with large seeded, tall... |

| There is widespread concern over the damage caused by modern agriculture to soil structure and the ecosystem services provided. One approach to overcome this problem is conservation agriculture (CA) which aims to maintain soil structure by minimising soil disturbance, maximising soil cover and using crop rotation. However, despite recent legislation supporting minimum tillage and direct seeding, together with the efforts of pioneer farmers, CA is still practised on less than 4% of the agricultural land in Europe. This underlines the need for major improvements in the approach together with consolidation of, and access to, information about alternative cropping methods and their biological and economic value and performance. A new European FP7-funded... |

| The co-evolution of plants with their pests and diseases is a major driving force in evolution in nature. As a consequence, many pests and pathogens have multiple functions involved in survival on host populations. As a result of this continuous co-evolution, plant pests and pathogens have been selected for high reproduction rates, because of the low probability of an individual being able to find or infect a compatible host plant. For their part, host plants in natural ecosystems are often interspersed among other plant species and show wide and changing variation among individuals for genes affecting specific or non-specific resistance to each of the many pathogens that may attack them. Throughout the plant world there are dynamic and unstable equilibria... |
