Management Guidelines

  • 4A545 is adapted to all U.S. production zones where fall dormancy 4, 5 or 6 alfalfas are normally recommended for hay or haylage. Best adapted to 28-30 day cutting schedules (by one-tenth flower) to maximize milk per acre.
  • Optimal harvest timing medium early maturity to one-tenth flower.
  • At harvest maturity look for tall showy plants, medium sized stems and a dense canopy of large, medium green leaves.
  • Excellent yield stability under 4 or 5 cut harvest systems and productivity into the later years of the stand.
