Interest in buckwheat production has been growing for several years now in Switzerland. Previously, this field crop had almost completely been forgotten. Since it is not related to other arable crops, buckwheat is ideal for breaking up crop rotations. It is also interesting from a nutritional point of view, as it contains zinc and selenium, and offers a gluten-free alternative to grain products for those who are gluten-intolerant. In order to produce recommendations for modern buckwheat cultivation in Switzerland, fourteen buckwheat varieties of different origin were grown between 2015 and 2018 in small-plot trials and compared in terms of their agronomic characteristics. The French variety La Harpe, which is cultivated in Switzerland, served as a reference crop here. In addition, the effects of different sowing densities on growth and yield were investigated using the varieties Devyatka and La Harpe. The variety trials showed that the newer breeds from Russia not only produced higher yields but also show a good early vigor and, due to their limited growth, remained shorter than other varieties, which simplifies harvesting in a direct threshing process. By contrast, investigating sowing density provided no conclusive answer to the question of optimal density: although yields tend to decrease with increasing sowing density, optimal sowing density should be determined on the basis of the situation in question, with 180 seeds/m² being a good initial density.
Tuta absoluta is one of the most destructive pests of solanaceous crops. Agroscope has developed a statistical model to study the population dynamics of the pest and its parasitoids and allows interventions to be optimally planned.
Swiss vineyards are often small and arranged in a mosaic of separate plots and management practices. Therefore, it can be assumed that spray drift from conventional to organic vineyards occurs regularly. Nevertheless, no pesticide residues are detected in most organic wines.

Red clover is one of the most important legumes in European forage production. In a multi-year field trial, researchers tested Europe’s largest collection of different red clover accessions at five European locations.
