Maximising grain yield of field peas locations

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

Key messages
  • Average grain yield was higher at Hart in 2011 (2.9t/ha) compared to 2010 (2.5t/ha) and 2009 (2.4t/ha).
  • Similarly to previous favourable seasons, no sowing time response was observed in 2011.
  • Blackspot severity was low in 2011 because spore release was high prior to sowing and emergence.
  • A 4% yield increase was achieved through fungicide applications but this was not economical in 2011.
  • Recently released PBA varieties Gunyah, Twilight, Oura and Percy all performed similarly to Kaspa.
  • Potential releases OZP0819 and OZP0903 both yielded 8% higher than Kaspa, while Alma was the lowest yielding variety, 7% below Kaspa.
