Management Guidelines

  • Best performance at moderate plant densities; avoid aggressive plant densities.
  • Excellent early season characteristics make this a good choice for reduced tillage systems.
  • Good choice for continuous corn and corn/soybean rotations.
  • Good choice for areas with high Goss's wilt pressure.
  • Not a strong candidate for delayed harvest, particularly when subjected to late-season moisture stress.
  • Very good northern movement and performance when positioned as a full-season hybrid. Maturity range is 91 to 96 days.
  • Good choice for early planting.
