| Currently the market demand for Swiss organic sweet cherries is far above the actual production. However, organic sweet cherry production is under high pressure to change the cultivation system and cultivars in order to meet the new requirements of the market for a regular supply of faultless and big-sized fruit. Additionally there is a necessity to for a more economical management. In this study we assessed the agronomic and economic result of a modern organic sweet cherry orchard over the first 4 cropping years. The orchard is equipped with modern cultivars like Kordia, Regina etc. and a plastic cover to prevent rain-due cracking and Monilia disease. Sideward’s an insect net is fitted to exclude cherry fly infestation. The results prove that... |

| Organic viticulture is an important part of the European Union organic farming sector, and, according to the most recent surveys, 1.5% of European Union wine originates from organic farms, with an upward trend. This paper describes an environmental impact of an organic viticulture indicator (EIOVI) that can be reliably used in the management of organic vineyards. The EIOVI can be used as a decision support system for farmers and other property managers by evaluating the potential ecological impact of their choices, thus optimizing management options. The tool allows the simulation of vineyard management based on six agricultural and ecological modules. The EIOVI is a fuzzy expert system that calculates the relationship between the modules on the basis of a... |

| The organic market has grown exponentially in Europe during the last ten years. However, the organic fruit industry has shown the lowest growth rates (1-5% market share) compared to other commodities. One major reason is the high production risk due to high disease and pest pressure in humid climates. Key pests and diseases in apple and pear include scab, sooty blotch, and fire blight as well as rosy apple aphid, pear sucker, and codling moth. In cherry, damages due to brown rot (Monilinia) and the cherry fruit fly make organic production almost unfeasible. In an ideal organic system, all possible measures that lead to improved stability of the system must be implemented. In fruit production, such measures include (i) use of resistant varieties (scab),... |

| Cocoa is a crucial export commodity for many developing countries and provides income for millions of smallholders. However, cocoa cultivation has resulted in habitat destruction, biodiversity loss and soil degradation. While much of the world’s cocoa is produced in arguably unsustainable full-sun monoculture systems, shaded agroforestry systems may be an alternative for sustainable cocoa production. However, data-based information on advantages and limitations of different cocoa production systems are limited and pairwise comparisons on the long-term performance of cocoa monocultures and agroforestry systems under conventional and organic management are literally inexistent. The Research Institute of Organic Agriculture (FiBL) is pioneering to fill this... |

| We implemented a system GDV Assistant (Gas Discharge Visualisation Technique) for parameterization and visualization of coronas of humans and plants. Besides standard parameters, developed by the team of Prof. Korotkov, the program includes some additional numerical parameters. In last few years in several studies we recorded coronas of apple tree leaves and fruits in order to verify and compare their vitality under different conditions. We used GDV Assistant for preprocessing and for numerical parameterization of coronas and we used various machine learning algorithms for analyzing the databases of parameterized corona pictures. The results of our studies show that coronas of leaves and fruits give useful information about the stress status of... |

| Zusammenfassung der Studie: Die vorliegende Literaturarbeit ist Bestandteil eines von Coop Schweiz mitfinanzierten Qualitätsprojektes am FiBL und hat zum Ziel, den Stand der vergleichenden Qualitätsforschung anhand von neueren Arbeiten darzustellen, die in zwei kürzlich erschienenen Literaturstudien (Woese et al. 1997, Worthington 1998) noch nicht erfasst sind. Insgesamt wurden 33 Studien ausgewertet. Davon können 19 Arbeiten als Vergleichsuntersuchungen zwischen bio und konventionell im engeren Sinn gewertet werden. Die restlichen Ergebnisse stammen aus Düngungs- und aus Sortenversuchen. 17 Arbeiten sind unseres Erachtens für die Qualitätsforschung von geringer Bedeutung. Neun Studien haben wir als mittel und sechs Arbeiten als wertvoll... |

| Orchards are perennial cultures, and, especially in organic fruit production it is essential to design and manage orchards in a way which favours beneficials such as insect predators and parasitoids over pests and diseases. As landscape-dominating crops their management affects overall biodiversity in the agricultural landscape. Increasing plant biodiversity and habitats in such a way that beneficials are favoured is called Functional Agro-Biodiversity (FAB). The value of FAB for reducing pesticide use in fruit production is generally acknowledged, and many growers try to increase it. However, they lack situation-specific information about how to drive and assess biodiversity to optimize FAB. ECOORCHARD is therefore combining several approaches: (i)... |

| Pilzkrankheiten, allen voran die Monilia (Monilia laxa, M. fructigena), stellen ein existentielles Produktionsproblem im Biokirschenanbau dar, stehen doch zu deren Regulierung bislang keine genügend wirksamen Präparate zur Verfügung. Indirekte Massnahmen wie durchlüftungsfördernder Schnitt und konsequente Entfernung der Fruchtmumien können zwar den Krankheitsdruck merklich reduzieren, reichen aber bei den meist stark anfälligen modernen Tafelkirschensorten bei ungünstiger Witterung nicht für eine ausreichende Ertragssicherheit aus. Diese Umstände bewirken, dass Biobetriebe bislang kaum in den Tafelkirschenanbau investieren und IP-Betriebe mit Kirschenanbau nicht auf Biobewirtschaftung umstellen. Bei neuen Tafelkirschenanlagen setzen sich aus ökonomischen... |

| Versuchsanordnung Der Versuch wurde bei Äpfeln der Sorte Pinova durchgeführt. Es handelte sich um die 3. Lese (12. Okt. 2003), da diese erfahrungsgemäss am meisten Gloeosporium gefährdet ist. Wir haben alle Behandlungen in einer 200 l Wanne (gefüllt mit 70 l Wasser) durchgeführt. In der Behandlung mit heissem Wasser wurde die Wassertemperatur durch Nachfüllen stabil zwischen 51.5 und 52.3°C gehalten. In den Behandlungen mit den Produkten "Jet 5" und Wasserstoffperoxyd haben wir die Produktkonzentrationen nach der Behandlung jeder Repetition durch Analysestäbchen von Merckoquant kontrolliert und je nach Bedarf mit dem jeweiligen Produkt nachgefüllt. Es wurden Fruchtkistchen von je 25 Früchten in 6 Wiederholungen pro Verfahren getaucht.... |

| Cocoa is one of the most important export commodities for many developing countries and provides income for millions of smallholders. The expansion of cocoa production has resulted in habitat destruction, biodiversity loss, and soil degradation. The prevalent cocoa production systems worldwide are conventional monoculture full sun systems. Agroforestry systems are argued to be a viable strategy for sustainable cocoa production. However, data-based information on advantages and limitations of different cocoa production systems is limited. Pairwise comparisons on the long-term performance of cocoa monocultures and agroforestry systems under conventional and organic management are inexistent. FiBL is pioneering to fill this knowledge gap with a unique... |

| In 1995, an experiment was planted at Wädenswil for comparing organic and integrated apple production. The overall goal of this experiment was to develop a data set which allows for an objective overall comparison of the two production concepts. Horticultural, ecological and economical traits were looked at. In practical terms, the study should particularly clarify how suitable the two systems are for producing marketable fresh fruit under Swiss conditions. The approach of an on-station comparison with a split-plot design with 3 replicate blocks and the factors “production system” (1st factor) and “variety” (2nd factor) was chosen. Ninety-four percent of Swiss apple acreage is managed according to integrated production, and 5% according to organic... |
