Management Guidelines
Best performance at moderate-low to moderate-high plant densities; avoid very aggressive plant densities to complement ear flex.
Good choice for reduced tillage or no-till systems.
Excellent root strength for poorly drained soils.
Excels in high-yield environments and responds to top management.
Maintain in-season fertility (nitrogen) to optimize performance.
Avoid light sandy soils unless irrigation is an option.
