“In the long-term field trial “”Oberacker”” at Zollikofen (Switzerland) crop yields were measured to determine the effect of no-tillage without any soil disturbance and conventional tillage with mouldboard plough. The collected data of the first five years of trial with the field crops winter wheat, winter barley, silage corn, sugarbeets, and potatoes were compared. Whereas no-tilled winter wheat and winter barley showed absolutely similar results, and even reached slightly higher yields on average than on conventionally tilled plots, silage corn showed no essential differences between the two tillage treatments on total dry matter production. However, cob yields on the no-tilled corn plots were on average clearly higher. Sugarbeets reached on no-tilled plots, after an initial yield reduction, the yield level of conventionally tilled plots, as well. In contrast, yields of mulch tilled potatoes did not satisfy in any year and were in terms of quantity – but even more so qualitywise – clearly below the level of conventionally tilled potatoes.”
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.
