Increased management flexibility with late grazing of dual purpose wheat under irrigation locations
Aims

The aim of this trial was to determine potential grain yield loss from a late grazing (cutting) relative to the increased grazing production.

Key messages

Mackellar wheat was cut at early‐mid stem elongation (GS32‐33), considered too late to be grazed without affecting grain yield, to determine effects under irrigation. Dry matter production was 22% higher compared with an earlier cut at GS30‐31 (start of elongation). With adequate soil moisture the late cut plots recovered well and grain yield was only 3% lower and not significantly different to the
earlier cut plots. Extended grazing of dual purpose wheat coupled with capacity to irrigate therefore provides increased economic and management flexibility.
