Annual ryegrass


Well known and very suitable for intercropping


  • Fast development and early maturity - excellent for sowing after early harvested cereals
  • Strong initially formation of bopmass guarantees a fast soil coverage and effective weed suppression
  • Excellent formation of green matter supplies high dry matter yields at the first cut
  • DIPLOMAT is well suited for sowing as pire seed but also for sowing in annual gras-clover-mixtures
  • Semi-erect to erect growth and good resistance to lodging form a good base for excellent fodder quality and low soiling
  • Enhances soil fertility, stimulates soil life and improves soil structure by supplying organic matter
  • Root residues stabilize the humus balance and protects the soil against erosion
  • DIPLOMAT is a diploid and in Northern Germany recommended variety
