Abstract

Grain legumes play a key role as a protein source and in cropping systems but their yields are perceived to fluctuate more than other crops. Therefore, an organically managed experiment on a research station in Northeastern Germany with eight monitoring trials from 1993 to 2013 was used to assess yields of two grain legume species (narrow-leafed lupin and field pea), two winter cereals (rye and wheat) as well as spring oats and silage maize. Two orthogonal data sets were analysed to compare individual grain legumes with cereals and silage maize in terms of temporal yield stability. Both grain legumes showed lowest average yields and lowest yield stability among the crop species; this was the case for both variance and regression type stability parameters. Causes for the low stability of grain legumes are still insufficiently known. Long- and short-term strategies need to be developed to reduce and adapt to high yield fluctuations of grain legumes in cropping systems
