Forage peas – a potential new break crop option locations

To assess the potential of the newly released forage (PBA Hayman) and dual purpose (PBA Coogee) field pea varieties as alternatives to vetch and grain field peas.

Key messages
  • Forage pea varieties produced similar levels of biomass to other peas and less than vetch at Hart in 2014. They were also more susceptible to blackspot than other pea varieties.
  • The value of PBA Hayman as an alternative to vetch will depend largely on being able to sow it early and control blackspot disease infection. This will often be difficult to achieve and sowing dates will need to be as early as possible around safe “black spot manager” predictions.
  • Where sowing of field peas was delayed, biomass was maximised by increasing sowing densities above 50 plants/m2 with little negative effect on grain yield.
