The possibilities of dead and living mulch were checked in three years trials comparing direct-mulch-planting and the traditional cropping system of potatoes. It is the aim to develop herbological methods in the new cropping system and to minimize N-leaching. The pre-forming of ridges after cereal harvest in the late summer and the type of green cover during winter do influence the weed infestation in the potato crop and their yield. Herbological methods have to be determined by the type of intercropping and the actual weed infestation. Efficient and secure weed control can be reached by pre-planting use of a non-selective herbicide to control living mulch and winter weeds and the use of a pre-emergence soil applied herbicide to control annual weeds. Protection against soil erosion is given.
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.
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.
