| This project was designed as an iterative process of describing quality profiles of “organic” and “high-quality” wheat and finding adequate, sensory-based methods to do so. Wheat growing in 1998-2000 at the DOK long-term field trial (FLIEßBACH et al. 2007, MÄDER et al. 2002) was repeatedly investigated. The ripening phase started earlier and lasted longer in treatment D2 (bio-dynamic) and was shortest in treatment K2 (conventional). Coded grain samples were examined in respect to treatment differ-ences in smell and taste. For D2 samples the author used the highest number of “sweetness” terms and the lowest number of other terms, whereas in M (conven-tional/mineral fertilizer only) grains, the highest numbers of “poorness” terms and the lowest of... |

| Europe is both a leading world market for and world producer of organic food. Growth of organically managed land and of domestic market values was strong in the past and continued during the financial recession, although at a slower rate. Many countries have specific plans for priority organic research and investment. Europe is a major producer of organic fruit crops, including a total of more than 900,000 ha consisting of 367,000 ha of olives, 92,700 ha of grapes, 187,000 ha of nuts, 94,800 ha of temperate fruit, 26,096 ha of berries, 31,800 ha of citrus, and 11,000 ha of subtropical fruit (2010). Western Europe added 4,000 ha of organic apples (Malus ×domestica) in 2010 and 2011 due to growth of the organic fruit market, a decline in conventional fruit... |

| Different research groups have already proven that flowering plants in orchards can enhance beneficial arthropods. Even within the tree rows different beneficial can be supported by selected plant species. In most experimental work done to stabilize the apple production system only single interaction effects were tested. However until now, no research group has quantified the additive effects of multiple measures on systembiodiversity and on the production economy. Our experiment combines all known measures of indirect pest and disease control measures in a near-to practical production model orchard without the use of any pesticide (not even organic ones). The orchard is split in 4 blocks: in two of them bio-control measures e.g. application of Granulosis... |

| The organic market has grown exponentially in Europe during the last ten years. However, the organic fruit industry in European states still has a relatively low market share of less than 1-5% compared with organic vegetables, milk and eggs that have achieved market shares of close to 10% of the total market. As well, conventional fruit growers still hesitate to respond to the generally good organic market demand. A major reason for this behaviour is the continuing high production risk due to less availability of effective management tools for the control of pests, diseases, weed and biennial bearing. The 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, as well... |

| Since 1994 important supermarket chains in Switzerland successfully sell apples from verified organic production. However, in supermarkets customers often ask whether there are, apart from a more environmentally friendly production, objective arguments of inner fruit quality that justify the higher prices of organic apples. In a field study with the ‘Golden Delicious’ cultivar, we harvested fruits of 5 pairs of organic/integrated fruit farms. The orchards within the pairs were less than 1 km from each other and were similar in micro climate, soil conditions and planting system. Maximum distance between the pairs was 180 km. To measure inner fruit quality we investigated at the beginning and at the end of cold storage (i) standard parameters (firmness,... |

| To evaluate the influence of compost on soil fertility and plant growth, several medium term and long term field experiments with composts were conducted in different crops. In two maize experiments, one in a sandy and one in a loamy soil, the influence of different composts and digestates on soil parameters and plant growth were investigated. All products increased pH of the soil and improved the biological soil activity (e.g., enzymatic activities). Immature compost immobilized nitrogen and reduced plant growth. Organic nitrogen fertilizer added during cultivation, could compensate the growth depression. A full factorial experiment in a 2-years-old organic apple orchard was conducted from 2001-2007. The factors tested in all 9 possible combinations... |

| In Switzerland there is an increasing consumer demand for residue-free, organic table grapes. The organic cultivation of table grapes, however, is very delicate in humid climates and experience to advice organic growers is still lacking. The goal of our project that has started in 2004 is to develop and establish a cultivation system for organic table grapes under Swiss climatic and economic conditions with a high yield security and fulfilling the high quality demands of the market. Preliminary results: Interesting cultivars to produce are e.g. Fanny, Lilla, Palatina. However they are disease susceptible and must be produced under a rain roof. Better suited cultivars still need to be found. Consumer acceptance for organic table grapes produced in... |
