Phosphorus rate by timing in wheat locations

To investigate the possible interaction between time of sowing and the phosphorus requirement of the crop at two locations (Birchip and Murtoa).

Key messages
  • In 2003, a three week delay in sowing after mid/late May resulted in a 0.3t/ha (Murtoa) and 0.5t/ha (Birchip) yield penalty.
  • Further delay in sowing (to July) caused similar decreases in yield.
