Introduction Cover crop services depend on biomass production and species composition of the cover stand. In this study, we investigated interactions in shoot dual mixtures their competitiveness to suppress weeds before winter under different growing conditions. Methods A field experiment was performed sandy loam soil Triesdorf, Germany, for two consecutive years. The white mustard ( Sinapis alba L.), oil radish Raphanus sativus var. oleiformis phacelia Phacelia tanacetifolia J.), Egyptian clover Trifolium alexandrinum common vetch Vicia sativa pea Pisum sativum bean faba L.) were grown pure stands or mixtures. crops sown August, harvested at end vegetation period. dried, share each test weed Brassica napus determined. Results a dual-species closely related its both years, showed similar when with second species. Regarding against weeds, cruciferous outperformed other could even if they mixed less competitive partner. Weed suppression depended component mixture more effective dry season. Legume species, especially not Discussion Our results show that high potential as single retain ability mixtures, regardless completes mixture.
