Screening Non Legume Species for Use as Cover Crop inMixtures

Several non-legume species have been tested for their suitability as cover crops, especially as constituent of mixtures with common vetch (Vicia sativa) and subterranean clover (Trifolium subterrananeum) in field trials performed in southern Germany from 2013 to 2016. We present selected results. The highest amounts of biomass were produced by Glebionis segetum, Anethum graveolens and Borago officinalis, which were also able to compete with subterranean clover and common vetch. All other tested species produced less biomass than the two legume species and were outcompeted in mixtures.
