“The fodder quality of meadows can be estimated quite precisely owing to the AGFF-leaflet number 3 “”Bewertung von Wiesenfutter, Nährstoffgehalt und Milchleistung””. Though a similar method which could allow the calculation of the yield potential is not available, we have an extensive set of data originating from numerous experimental sites at our disposal. We therefore attempted to estimate the potential of production of clover-grass mixtures with a calculation model accounting for differences in cultivation intensity (nitrogen fertilisation and frequence of utilisation) and in ecological site conditions (rainfall pattern and altitude).”

Five Merlot clones bred in Switzerland are currently being distributed by the certification sector. A multiyear trial conducted by Agroscope in Gudo (Canton of Ticino) has made it possible to compare them with French and Italian reference clones and to highlight their very good performances.
Arbuscular mycorrhizal fungi are important for healthy soils and crops. A pan-European study shows that plant-protection products adversely affect these fungi, reducing their ability to supply plants with phosphorus via their roots.
Birdsfoot trefoil and sainfoin are used in mixtures for perennial hay meadows and for tannin-containing fodder. Agroscope is adding two new cultivars of birdsfoot trefoil to the ‘List of Recommended Varieties of Forage Plants’, whilst there is no change in the case of sainfoin.
