Maximising grain yield of field peas locations

To identify optimum sowing times in new field pea varieties and to improve recommendations from the ‘Blackspot Manager’ disease risk prediction model in different regions.

Key messages
  • Grain yield of field peas sown at Hart in 2010 averaged 2.5t/ha across all varieties.
  • No time of sowing response was observed in 2010.
  • Early sown plots with uncontrolled blackspot showed a 35% yield loss compared to the optimum control (fortnightly chlorothalonil), which yielded 3.6t/ha.
  • Prospective releases OZP0703 and OZP0903 show a lot of promise, with OZP0703 performing similarly to Kaspa and OZP0903 yielding 10% greater.
  • Chlorothalonil (Bravo), pyraclostrobin (Cabrio) and azoxystrobin plus chlorothalonil (Amistar Opti) increased yields compared to the nil treatment with disease pressure.
