To investigate management strategies to close the yield gap and reduce pre-harvest losses in Barley in 2022 and 2023. 

• Barley grain yield averaged 4.61 t/ha and ranged from 3.82 to 5.42 t/ha resulting from variety choice and management strategies.
• High fungicide inputs were required to maximise grain yield for RGT Planet, Cyclops and Leabrook across two consecutive years. High fungicide input was most profitable in varieties with leaf rust susceptibility and with high infection levels during grain fill.
In the absence of leaf rust, high fungicide inputs were not profitable.
• There were no yield gains resulting from increasing nitrogen (N) application from low to high (60 – 140 kg N/ha). RGT Planet grain yields decreased in response to increasing nitrogen supply. High N supply also increased grain protein for all varieties, preventing them from meeting malt receival specifications.
• The application of plant growth regulators (PGRs) reduced crop lodging at the early time of sowing, however no yield increases were observed.
• The use of simulated grazing at GS 30 (beginning of stem elongation) resulted in a significant yield reduction for RGT Planet and Leabrook of 220 kg/ha and 180 kg/ha, respectively. No yield reduction was observed for Cyclops.
