1. To compare the yield of three times of sowing (March, April, May) for Mowhawk winter wheat.
2. Compare the performance of oats vs winter wheat in early sowing windows.
3. To compare the yield of early sown winter wheat against spring wheat sown during its ideal sowing window.
• Early Sowing Opportunities: In years with early rainfall, growers can confidently sow Mowhawk or Bannister in late March to capture early moisture and extend the cropping program.
• Dual-Purpose Systems: Both Mowhawk and Bannister offer grazing potential, but oats recovered better post-grazing, had higher biomass and maintained higher yield.
• Weed Control Planning: Effective ryegrass management is essential for winter wheat success. Clean paddocks and flexible herbicide strategies are critical.
