Vaisman, I., Entz, M. H., Bamford, K. C. and Cushon, I. 2014. Green manure species respond differently to blade rolling. Can. J. Plant Sci. 94: 1507-1511. Reducing tillage in green manure (GM) management has led to interest in using the blade roller in organic agriculture. This study investigated the interaction effect of GM termination method (blade rolling and conventional tillage) and GM species choice [chickling vetch (Lathyrus sativus L.), Indian Head lentil (Lens culinaris), and hairy vetch (Vicia villosa Roth)] on a subsequent crop of hard red spring wheat (Triticum aestivum L.). Significant effects on weed density and biomass, wheat biomass, and wheat yield indicated that the GM species were affected differently by termination methods. It was also discovered that spring-seeded hairy vetch continues to grow after rolling, while chickling vetch and lentil die.
