L70 Lucerne Seed - Winter Active



L70 Lucerne Winter Active

Medicago sativa

L70 is available to the Australian domestic market having been a successful export replacement for Aurora. With significant Australian production of L70 now coming on stream this allows us to position this exciting new Aurora replacement with Australian farmers. The ability of L70 to achieve consistent seed yield returns now allows us to position the new L70 Lucerne at a very competitive price. L70 exhibits excellent forage traits and good disease profile.
L70 vs. Aurora

    • L70 offers higher disease and pest package compared to Aurora.
    • Superior forage genetics – higher leaf to stem ratio.
    • Minimum 90% germination standards (current minumum certifed standrad for Aurora-60%)
    • L70 seed production is derived from dryland seed production stands only. Thisis to ensure the dryland integrity and performance of L70, when utilised in standard ceral undersowing practices and marginal dryland grazing enterprisesL70.
    • These attributes combined with superior plant genetics, makes L70 an excellent new Lucerne option over Aurora. This gives Australian farmers higher returns and extra confidence with the Establishment Guarantee program that commons based lucerne cannot offer or compete against

      • Perennial, year round production.
      • Deep rooting, extracts water and nutrients from depth, restricts water table recharge.
      • Moderate tolerance of soil salinity and sodicity.
      • Responds quickly to spring and summer rainfall (or irrigation).
      • Dual purpose (grazing and hay).
      • Highly productive.
      • High nutritive value.


      • Short-term persistence in some regions (mainly due to disease susceptibility).
      • Susceptible to waterlogging.
      • Needs rotational grazing.
      • Can cause bloat in cattle.

Plant Description


    • Deep rooted, upright, perennial legume.


    • Erect from 40 – 80 cm high at 10% flower.


    • Comprise three smooth, slightly toothed, oval, wedge shaped to pointed leaflets, sometimes with white crescent shaped markings. Leaf veins strong, straight with little branching. Broadly triangular stipules with one or more small teeth occur at the point of leaf attachment to the stem.


    • Pea flowers, mostly purple in colour, and about 8 mm across, borne in clusters up to 4 cm long at the tops of branches.


    • 4 – 5 coils in a spiral, spineless with a hard outer surface; produced in clusters; 1 – 5 seeds/pod.


    • Small, green to yellow to light brown in colour; kidney shaped; 440,000 – 500,000 seeds/kg.

Pasture type and use

    • Medium term perennial (3 – 5 years); year-round production, predominantly in the spring/summer but with varying levels of winter production (winter activity). Used for conservation, particularly hay production; as a ‘ley’ legume in cropping rotations (often called a ‘phase’ legume in such systems in southern and Western Australia); and as a medium-term legume in long term grass pastures in the subtropics.

Where it grows


    • In rain grown stands, 500 – 1200 mm/annually (subtropics); 250 – 800 mm/annually (southern and Western Australia).


    • Lucerne requires deep, well-drained soils (sands to moderately heavy clays) with a slightly acid to alkaline pH. It is intolerant of high levels of exchangeable aluminium and even short periods of waterlogging.


    Optimum temperatures for dry matter production range from 15 – 25_C in the day and 10 – 20_C during the night. However, this will vary with the winter activity level of the cultivar.

Animal production

Feeding value: 

      • Lucerne is highly digestible (60 – 75 %), is a good source of crude protein (15 – 25 %), and has high levels of metabolisable (8 – 11 MJ/ kg DM).


      • Very palatable.

Production potential: 

      • Daily live weight gains for beef cattle range between 0.7 kg/head/day from stemmy lucerne to 1.5 kg/head/day from young, leafy regrowth. Live weight gains of 300 – 400 g/head/day are achievable with lambs.

Livestock disorders/toxicity: 

      • There are few problems. To avoid cattle bloat, nitrate poisoning and red gut, do not graze immature/lush lucerne, especially with hungry stock (pre-feed with dry roughage).
