Management Guidelines

  • Adapted across all northern U.S. production zones where alfalfa with fall dormancy of 3, 4 or 5 are normally recommended; best suited to 30- to 32-day cutting schedule to maximize milk production per acre.
  • Recommended planting rate to ensure full production as pure alfalfa stands: 16 to 18 pounds per acre; reduce pounds when seeding as a component in cool-season grass mixtures.
  • Excellent seedling vigor scores for rapid stand establishment, which is especially important for late-summer seedings.
  • Medium to medium-late days to one-tenth flower maturity.
  • At harvest maturity look for a very uniform medium plant height and a leafy trifoliate canopy of medium green leaves on a fine stem.
  • Average recovery after harvest.
