Tall oat grass and golden oat grass are typical hay-meadow grasses that are also suitable for forage mixtures. Of the four tall and three golden oat grass varieties tested, only one new variety of tall oat grass is likely to make it onto the List of Recommended Varieties.
FiBL and Agroscope investigated bread wheat varieties to determine their yield and quality stability. The results show that the choice of variety must be adapted to the site and that high yield potential does not go hand-in-hand with a high protein content.
Adapted and high-yielding varieties of forage plants are important for Switzerland as a grassland country. Hybrid ryegrass is a versatile forage grass that, thanks to breeding advances, has become even more persistent, disease-resistant and high-yielding over the past 30 years.
Herbicide-resistant weeds are a growing problem throughout the world. Monitoring herbicide resistance in Switzerland allows us to understand the mechanisms behind it and to better manage the use of herbicides.
Agroscope compared crop protection strategies in apple production. Reducing the use of plant-protection products lowered the local ecotoxological risks, but resulted in trade-offs between environmental and economic performance.
Bacillus thuringiensis (Bt) bacterium proteins protect Bt maize from being fed on by specific insects. A new, systematic analysis of international field data confirms that non-target organisms in Bt maize are largely spared.
A natural antagonist of Drosophila suzukii, a parasitic wasp from its native range, is harmless to the native non-target species Drosophila melanogaster. This has been proven in trials in secured field cages in Switzerland.
To reduce plant-protection product use, we need to know what behavioural patterns farmers follow when using plant-protection products in their crops. This was the subject of a study conducted by Agroscope in Switzerland.
Crimson clover is essentially used as a catch crop in association with ryegrass. The comparative trial conducted in 2019-21 has led to the addition of two new acquisitions to the List of Recommended Varieties of Forage Plants.
To ensure a good harvest while protecting the environment, a nitrogen surplus must be avoided. Agroscope is investigating how the application of nitrogen fertiliser can be better adapted to soil replenishment and the needs of the plants.
Arbuscular mycorrhizal fungi are like a “life-insurance policy for plants”. They improve soil structure and make nutrients and water available. This increases the stress tolerance of crops and leads to better yields.
The invasive weed yellow nutsedge creates considerable problems for Swiss producers in arable and vegetable crops. In a four-year project, stakeholders from research and practice evaluated various control strategies on-farm.
Wireworms cause significant crop losses in potatoes. This study investigated the efficacy of a fungus in decimating wireworm populations in the winter cover crop. The strategy was partially successful, but must be further optimised for use in practice.
Bacterial diseases can have a huge impact on potato production yields.
The method for detecting these diseases used in Switzerland to date does not allow the growing demand for tests to be met. Agroscope is implementing new solutions.
Hybrid ryegrass is a high-yielding, versatile forage grass used in many clover-grass mixtures. Out of a total of 23 tested varieties, two new varieties performed particularly impressively in terms of yield and resistance to bacterial wilt.
Italian ryegrass is a high-yielding meadow grass that is often used in clover-grass mixtures. Out of a total of 52 varieties tested by Agroscope, two new frontrunners scored top marks for nearly all traits.
Consumer acceptance plays a key role in the introduction of new grape varieties. An Agridea consumer survey reveals a great openness to fungus-tolerant varieties that lend themselves to particularly environmentally friendly cultivation methods.
BFH-HAFL investigated three non-hardy green-manure mixtures and their effect on organic maize: A legume-rich green manure showed very high nitrogen enrichment and a positive effect on the early juvenile development of maize.
A secured field on Agroscope’s Reckenholz site enables field research with genetically modified (GM) plants. In addition to research results, it provides findings on how GM plants might be handled in agriculture, as well as offering the public a window into this research.
Fungal toxins in wheat endanger the health of humans and animals. Agroscope investigated three cropping systems under reduced tillage to improve the quality and yield of wheat harvests using alternative crop protection strategies.
Fruit and wine producers who receive information from the public sector are more likely to use preventive measures such as nets or hygiene measures to combat spotted-wing drosophila. Producers advised by private firms that sell plant-protection products are more likely to use synthetic insecticides.
Maize is one of the most important crops in Switzerland. Variety selection and site adaptation play a crucial role in maize cultivation in a changing climate. Heat-supply maps created by Agroscope help in the choice of suitable varieties.
Tall fescue is valued as a high-yielding, robust forage grass. For ley farming, fine-leaved, nutritious varieties which are well-liked by livestock are in demand. Agroscope’s most recent variety test has yielded two new top varieties.
Despite its focus on other, higher-priority criteria, the soybean breeding programme in Switzerland has yielded varieties that are tolerant of soybean mosaic virus (SMV) – the most serious of the viral diseases.
Chlorpropham (CIPC), the main sprout suppressant used when storing commercial potatoes, is now prohibited in Switzerland. Agroscope tested alternative substances in order to guarantee the production of indigenous chips and crisps.
