To increase yield of barley in the high rainfall zone with improvements in barley crop management that considers all aspects of canopy management (genotype, PGR, Fungicide, Nitrogen, and Defoliaton).
- RGT Planet and Rosalind were the only varieties to achieve yields of over 7t/ha.
- Crop canopy management treatments were significant and ranged from 5.77 through to 6.55t/ha
- Despite producing adequate biomass for higher yields, harvest indices at this site were low and the cause of this needs to be explored further.
- Two DMI fungicides were sufficient to control disease with no benefit of a higher input (including SDHI and QoI actives) fungicide regime.
- The largest spread in yields from management was observed in Planet highlighting the importance of management in this cultivar,This is consistent with other HYC data.
- Given the absence of significant yield loss to disease, lodging or head loss, the response to management treatments was generally insignificant, with increasing N from 126N to 219N showing the greatest benefit.
- Defoliation did not significantly reduce yields in Planet and Rosalind and highlights that delayed flowering and canopy management was potentially an advantage in 2021.
- There is evidence of higher grain screenings in the winter cultivars with screenings over 4%, whereas below 2% in the springs
- However, even with a wet and cool grain filling, the 2 row winter barley Madness tested in this trial matured too late and was not competitive for yield.
- Faster winter barleys are likely to be required for WA’s high rainfall zone, however the 6 row winter Pixel achieved similar yields to Laperouse in 2021, but less than Rosalind and Planet.

Plant Breeders’ Rights (PBR)
Some crop varieties used in research trials may be covered by Plant Breeders' Rights (PBR). Users should confirm PBR status of relevant varieties by searching the IP Australia PBR database, http://pericles.ipaustralia.gov.au/pbr_db/ or Variety Central (http://varietycentral.com.au/) and contacting variety owners for further information if required. Where possible, varieties have been listed according to their registered PBR name, although OFT cannot and does not guarantee that the information is accurate or complete.
