Between 2003 and 2005 Agroscope Reckenholz-Tänikon (ART) and Changins-Wädenswil (ACW) had been conducting trials with 25 varieties of white clover and four varieties of bent grasses at five and eight experimental sites, respectively. For comparison of the varieties, data on yield, juvenile development, persistence, disease resistance, winter hardiness, competitive ability and adaptation to higher altitudes were obtained. With the data of the observed traits an index value was calculated, allowing for a general evaluation of the varieties. Corresponding to the results of the trials, the white clover variety Tasman will be added to the «List of Recommended Varieties of Forage Plants». With bentgrasses this is the case for the varieties Gudrun and Janek. Several varieties which were tested attained an index value that would allow for recommendation but cannot be added to the list because they are not eligible for trade in Switzerland yet.
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.
