Summary

Winter peas were cultivated in Germany in the first half of the 20th century for green manure, green forage or as a threshing crop. So far they are mainly used in field ex-periments, e.g. at the University of Kassel. But winter peas are very interesting for or-ganic farming, because of their high N-fixation rate and their ability to suppress weeds effectively. In the vegetation period 2002/2003 twelve genotypes of winter peas from the German genebank in Gatersleben were examined in field trials. In the long and cold winter of 2002/2003 eight different genotypes from Germany, Hungary and the Balkan survived. The yield of the eight accessions as green forage and as a threshing crop (yield between 3 – 4 t/ha) are promising.
