Within the framework of a European project called GL-Pro (European extension network for the development of grain legume production in the EU), a crop demonstration network for grain legumes was set up in order to evaluate the potential of these crops and to contribute thus to their development. In Switzerland, crops were grown by farmers and were observed to evaluate their specificities, assets and weaknesses. These results were compared with those obtained in the European network. Field pea shows the highest and most stable yield. Spring faba bean and white lupin represent interesting alternatives. Pea is the best adapted wintering grain legume. The cultivation of winter faba bean is also possible. Blue lupin provides lower yield, whereas winter lupin represents too many risks under the Swiss climatic conditions. On the basis of results obtained from 2003 to 2005, grain legumes show a great sensitivity to the climatic conditions leading to sometimes insufficient yield levels and stability. The diversity of species is large in Switzerland and can make it possible to mitigate these problems.
