1. Link tactical agronomy to physiological changes in the critical period and yield.
2. Identify key benchmarks (crop and soil traits) for actionable decisions during the season.
3. Lift water-limited yield potential in low to medium rainfall zones.
• A new GRDC project focuses on connecting crop agronomy practices to maximise grain number production and yield potential.
• Modern genetics and advanced crop management are delivering higher water use efficiencies, achieving transpiration efficiencies greater than 25 kg/ha/mm and evaporation losses below 60 mm.
• An extra 30 mm of water in the critical period increased wheat yield by 0.6–1 t/ha at Hart, a transpiration efficiency for grain yield of 20–33 kg/ha/mm.
• Barley suffered greater yield loss than wheat in 2024 at Hart and requires more analysis of water use patterns.
