Icon Lucerne

Icon lucerne was developed by selection from old established lucerne stands where high plant populations have survived over time. Plant selection was based on superior forage yields, improved disease and pest tolerance.

Icon plants are moderately tall with leafy stems and a high leaf to stem ratio. With a winter activity rating of 6-7, plants have good winter, spring and summer growth, (where moisture is available), with vigorous recovery from cutting or grazing.

Icon attributes:

  • Good level of Winter activity (rating 6-7)
  • Well suited for use in cropping rotations
  • High nitrogen fixation for following crops
  • Improved disease & insect resistance
  • Higher productivity
  • Australian bred for Australian conditions

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

Being winter active, Icon 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.
