Improving water use efficiency – crop rotations locations
Aims

To assess the performance of wheat following either peas, wheat or barley.

Key messages
  • At three out of the 4 sites gladius wheat sown onto a pea crop background from 2011 produced the best grain yields.
  • At Condowie wheat on barley (2.54t/ha average) was always better than wheat on wheat (2.10t/ha average), regardless of extra nitrogen.
