Sown: 16 April 2022
Harvested: 16 November 2022
Rotation position: 1st Cereal after canola, 2020 wheat.
Soil Management: Sand Plain, Sand over Clay.

Key Messages:

• Despite earlier phenology, Rosalind grown with higher inputs of nitrogen (46N extra over 120N), fungicide (three units instead of two) and PGR produced significantly higher yields than other cultivar/management combinations, however higher spot form of net blotch and powdery mildew made it the most input responsive cultivar.
• RGT Planet was significantly lower yielding than Laperouse under lower input management but yielded almost identically when grown under higher input, fungicide input looked to be the most influential input in this result. A result identical to the 2021 season.
• There was a significant interaction between cultivar and management indicating that cultivars responded different to the management strategies applied.
• There was no advantage to growing a short season winter barley (cv Urambie) despite the mid-April sowing date resulting in spring barley cultivars reaching GS31 in mid – late June. (Note this is a generally frost free location, with no frost experienced this year).
• Grain yields resulting from management input correlated strongly to crop canopy dry matter at harvest. For the high input management, the mean harvest index was 48.1% (grain yield based on 0% moisture).
