Between 2000 and 2002 the Swiss Federal Research Stations for Plant Production at Changins (RAC) in Nyon and for Agroecology and Agriculture (FAL) at Reckenholz in Zurich conducted comparative trials with 32 varieties of cocksfoot at five experimental sites. Based on measurements and observations of yield, persistence, competitive ability, disease resistance and digestibility of organic matter (DOM) an index-value was calculated allowing for an accurate comparison of the varieties. The following varieties have been newly accepted in the Swiss «List of Recommended Varieties of Forage Plants»: Barexcel, Geenly, Foly and Quantum.
Spring J.-L-, Zufferey V., Verdenal T., Reynard J.-S., Lorenzini F., Bourdin G., Blouin A., Carlen C., Jermini M., Morisoli R., Ferretti M.
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.
