Field pea nutrition trials locations

To investigate the potential for response to P rates above 15 kg/ha.

Key messages
  • Significant grain yield responses to P fertiliser application occurred at the Goonumbla site.
  • At Goonumbla, 25 kg P/ha significantly increased grain yield over 15 kg P/ha only when applied with starter N.
  • Field peas proved very sensitive to heliothis damage at Gunning Gap and to harvest delays at Wirrinya.
