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.
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.

Spring sown barley summary: 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. |
