Sown: 29 April 2023
Harvested: 20 November 2023
Rotation position: 2022 Canola
Soil type & management: Forest gravel loam

Objectives:
To assess the performance of five spring barley germplasm choices, managed under four different management intensities, sown in late April in the Frankland River (WA) HRZ environment. G.E.M – Germplasm x Environment X Management.

Key points:
- There was a significant interaction between cultivar and management approach with cultivars responding differently to the level of management being applied.
- All cultivars, except the longer season barley Laureate, out-yielded RGT Planet under low input 125 N (125kg N/ha), two triazole fungicide applications -Tilt/Opus).
- From grain yield and protein analysis there appeared to be no advantage to additional N
inputs, that were associated with either High input management (175 N) or HYC Tactical
management approaches (150 N) over the 125 N adopted for Low input and HYC management strategy.
- However, RGT Planet, Neo, Minotaur and Rosalind cultivars responded significantly to greater fungicide input in the HYC Strategic approach based on two foliar fungicides (Prosaro/Aviator).
