Irrigation Discussion Group Focus Paddock - Irrigated barley PGR locations
Aims

The aim of the trial was to assess the influence of PGR and nitrogen rates on the standability, head loss and yield of
an irrigated barley crop. We also wanted to observe the fit for PGR’s in a later planted crop with perceived yield
limitations due to season length.

Key messages

GPR are a tool that can be used to manipulate the canopy of a cereal crop to reduce the risk of lodging and head
loss. There was no benefit from applying PGR’s in this circumstance but given more favourable seasonal conditions
and a higher yielding crop benefits in harvestability and yield may have been observed.

Waterlogging

Continued rainfall through late winter and spring meant that fertiliser treatments and later PGR applications planned for this demonstration could not be applied. Yield was approximately half expectations.
