Hyper Yielding Crops Project (FAR2004-002SAX)
Trial 3. HYC G.E.M Trial Series – Time of sowing 1
2023 WA Crop Technology Centre (Frankland River)

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).
