RM4 woolly pod vetch was developed from the highly successful SARDI Vetch breeding program. RM4 has excellent early vigor which leads to better establishment (3–5 nodes form in about 45 days) than other varieties. It is earlier in flowering and grain/seed maturity, up to 10–15 days earlier than Haymaker or Capello. RM4 is soft seeded and was selected as a new woolly pod variety for dry matter and seed production in areas of rainfall <380mm/yr as well in higher rainfall areas  >400–650mm/yr.


Key features

  • Best early vigour of all lines in  SARDI research trials
  • Long term average dry matter yield 108% of Capello
  • Early maturity, it can be cut for  hay 10–15 days earlier than  current varieties
  • Soft seeded
  • Good frost tolerance in  international testing


Key benefits

  • Multipurpose variety - can be  used for hay/silage, grazing &  green/brown manure
  • Early vigor gives grower flexibility as they can graze or cut for hay quicker
  • Improves soil fertility with nitrogen fixation, which benefits following crops
  • Soft seeded means less volunteers  in following years



The recommended planting rate for RM4 Woolly Pod Vetch is: 15 – 35kg per hectare.  Sowing rates are related to the end use targeted and rainfall areas. Higher rates are required for hay/silage, grazing and green manure (30–35kg/ha) and 15–20kg/ha used for grain/seed production. Sowing time is the same as other woolly pod vetches.  


Agronomy and management

Paddock selection and basic requirements for growing RM4 are similar to other woolly pod vetch varieties. Good control of weeds in early growth stages is very crucial, as vetch are poor competitors to weeds in early growth stages, when vetch reaches 20–25cm height it is competitive with broadleaf and grassy weeds. Suitable to graze from 15 nodes up to finish of flowering. For hay/silage, cut in full flowering for the best balance of feed value. RM4, like other vetches is excellent for soil fertility/structure and nitrogen fixation. Turn into soil or desiccate at flowering time. RM4 was not sensitive to any herbicides recommended/registered for use in woolly pod vetch varieties. As with all woolly pod varieties, RM4 grain is toxic to stock and hence it is critical that hay or grazing occurs before pod set.



RM4 can be successfully grown, like other woolly pod varieties in many soil types. RM4 performs better in grain productions than other woolly pod varieties when season finishes sharply.



Disease / pest resistance

RM4 is moderately resistant to ascochyta blight. It is susceptible in early growth stages to red-legged earth mite and alfalfa flea, like other woolly pod vetch varieties. Also, RM4 is susceptible to blue-green and cowpea aphids from early growth through to pod maturity, as well as to native budworm during pod formation and filling.
