Key messages

There was no significant response to fungicide for grain yield or grain quality from spring sowing (table 1 and table 2).
Disease levels were low, but despite up to 20% of the leaf area affected with net form of net blotch and scald there was no yield response (figure 1).
Spring sown barley is incredibly robust, the canopy develops rapidly and disease develops later and has less impact on grain yield.

This is a similar finding to 2020, and demonstrates intensive fungicide inputs, and more expensive SDHI chemistries may not be required to the same degree as autumn sown systems (see Millicent results 2021).

Other trial notes

Spring sown barley summary:
Peak yield of 10.98t/ha was achieved in 2021, 10t/ha can be consistently achieved across diverse management regimes in Planet.
Further evidence that harvest index rapidly declines in barley at 16t/ha of dry matter.
Laureate has high yield potential but is more prone to lodging and brackling.
Higher N rates increased brackling and Lodging.
Evidence to suggest harvest indices approaching 60% are possible in irrigated spring sown barley.
Fungicide management is easier in spring sown barley compared to Autumn sowing barley.
PGR responses were variable for lodging and brackling, but later applications reduced head loss.
A 14 day harvest delay did not result in significant yield loss in 2021 and PGR treatment had little impact.

The key feature of the Tasmania HYC Barley site is the fact it is spring sown and supplemented with irrigation. This presents different challenges to growing barley such as a greater chance of heat risk during grain fill, and brackling from rapid growth during stem extension. Cultivars that are less responsive to longer days (photoperiod) are also required to ensure they do not develop too early and build insufficient biomass.
