Aims

To assess the value of PGRs with spring sown barley in HRZ regions to increase yield and reduce lodging, brackling and head loss. A harvest delay will be imposed to exacerbate treatment differences.

Key messages

Despite high yields and a 14 day delay in harvest further yield losses and a higher incidences of brackling, lodging, and headloss did not occur from later harvest.
Irrespective of harvest timing PGRs increased yield in Rosalind by 0.5t/ha across all timings, were as yields were the same in Planet (Table 2).
Brackling and Lodging responses to PGRs were variable and not consistent.
Later applications od PGRs reduced headloss in both cultivars, however numbers were low and too insignificant to reduce yield.

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.
