Field peas - maximising grain yield through sowing times locations
Aims
  • To identify best sowing time and fungicide strategies for maximum grain yields in field peas.
  • To improve the reliability of the SARDI blackspot disease prediction model and validate the blackspot predictive model ‘Blackspot Manager’ in SA by incorporating data from replicated trials.
Key messages
  • Early sowing of field pea is essential for economic yields in dry years in low rainfall environments, providing frost, weed and blackspot risks are considered.
  • Kaspa & OZP0602 had lower disease severity and slower build up of blackspot than the old Alma cultivar.
  • Strategic applications of foliar fungicides led to a small but significant reduction in blackspot.
  • Sowing field peas on the season break will increase blackspot risk however exposure to risk can be reduced through the use of the blackspot predictive tools (Blackspot Manager and DIRI) and careful paddock selection.
