Blue Ace Lucerne

Blue Ace lucerne was developed by selecting plants from within disease resistant survivors in old lucerne stands. Plants were selected on plant characteristics of superior fodder yield, improved pest and disease resistance.

Blue Ace plants are moderately tall with leafy stems. With a winter activity rating of 9, plants have strong winter and spring growth with vigorous recovery from cutting or grazing.

Blue Ace attributes:

  • High Winter activity (rating 9)
  • Well suited for use in cropping rotations
  • High nitrogen fixation for following crops
  • Improved disease & insect resistance
  • Higher productivity
  • Australian bred for Australian conditions

Blue Ace is suited to dryland or irrigated lucerne growing areas and performs well in sites where disease susceptible varieties will not persist.

HR = Highly resistant; R = resistant; MR = moderate resistant; S = susceptible; ∼ = No data. 

Being highly winter active, Blue Ace can be sown through the early winter to early spring period and is suitable for under sowing cereals or as a rotation crop.

Establishment Tips

  • Choose a paddock 12 months prior to sowing lucerne which is free draining and do a soil test. Apply lime if pH is below 5.0 (CaCl2)
  • Plan for weed and pest control in year prior to sowing e.g. crop paddock prior to sowing lucerne.
  • Area sown should be sprayed for insects e.g. bare earth like canola
  • Lucerne seed should be inoculated with group AL at the time of sowing
  • After sowing light roll to preserve moisture if possible.

Recommended sowing rates:

Dryland: 4 to 10 kgs/ha; Irrigation: 10 to 20 kgs/ha.
