Alpha 1 Lucerne

Highly winter active lucerne with a high leaf to stem ratio

Medicago sativa

UnavailableDownload tech sheet

Alpha 1 Lucerne was bred from Australian, USA and Argentinian germplasm and was selected for increased winter activity, fast establishment, and finer stems with high leaf to stem ratio and improved disease and pest resistance. The increased leaf to stem ratio will also give higher protein and digestibility.

Key attributes

  • Increased winter growth (rating 9)
  • Finer stems and higher leaf to stem ratio
  • Improved disease and insect resistance
  • High nitrogen fixation for following crops
  • Can be sown as a longer-term break crop to reduce disease risk
  • Vigorous recovery from cutting or grazing

About this variety

Alpha 1 Lucerne displays strong autumn and winter/spring growth with vigorous recovery from cutting or grazing, this is an advantage in close grazed pastures and intensive forage cutting programs.

Alpha 1 is suited to dryland or irrigated lucerne growing areas. Being highly winter active, Alpha 1 can be sown through the early winter to early spring period and is suitable for under sowing cereals or as a rotation crop.

A replicated independent dryland lucerne trial conducted at Ballarat in Victoria showed Alpha 1 Lucerne as one of the best yielding varieties during a period of extreme dry conditions.

Planting & grazing notes

Choose a free draining paddock 12 months prior to sowing lucerne and complete a soil test; apply lime if the pH is low. Plan for weed and pest control in the year prior to sowing, e.g. crop the paddock prior to sowing lucerne. The area sown should be sprayed for insects, e.g. bare earth like canola. Sow at a depth of between 1-2cm, inoculate the seed with group AL at the time of sowing, and light roll after sowing to preserve moisture. Being highly winter active, Alpha 1 can be sown through the early winter to early spring period.

Disease & pest resistance

Spotted alfalfa aphid: resistant. Blue aphid: highly resistant. Pea aphid: highly resistant. Anthracnose: moderately resistant. Fusarium: highly resistant. Phytophthora root rot: resistant.

FAQs

Can I sow lucerne later in the season, like early winter or even spring?

Yes. Our Alpha 1 Lucerne is highly winter active, so it can be sown from early winter through to early spring. Sow at 1 to 2 cm, inoculate with Group AL at sowing, and lightly roll afterwards to conserve moisture. It suits both dryland and irrigated lucerne growing areas.

How much lucerne seed per hectare in 350mm country compared to higher rainfall?

We recommend Alpha 1 Lucerne for areas with 400mm+ rainfall, so for 350mm country we suggest our Sceptre Lucerne, which suits 350mm+ at 4–10 kg/ha dryland. For Alpha 1 in 400mm+ country, sow 4–15 kg/ha dryland, matching the rate to your rainfall, or 15–25 kg/ha under irrigation. Sow 1–2cm deep and lightly roll.

How do I prepare a paddock for lucerne a year ahead?

We recommend choosing a free-draining paddock 12 months before sowing and soil testing it. Apply lime if pH is below 5.5 (CaCl2), and plan weed and pest control the year before, for example by cropping it first. This is the approach we recommend for Alpha 1 Lucerne to get a clean, strong start.

Which lucerne has the best aphid resistance?

Our Alpha 1 Lucerne is rated Highly Resistant to blue green aphid and pea aphid, and Resistant to spotted alfalfa aphid. It's also Highly Resistant to Fusarium, Resistant to Phytophthora root rot and Moderately Resistant to anthracnose. That profile helps stands stay productive under pest and disease pressure.

I want a break crop that fixes nitrogen and cuts disease before going back to wheat, any ideas?

Alpha 1 Lucerne works well as a longer-term break crop. It fixes high levels of nitrogen for following crops and can help reduce disease risk by breaking the cereal disease cycle. It can also be under-sown with cereals or used as a rotation crop, and it provides grazing while it's in.

Can I undersow lucerne with a cereal crop?

Yes, Alpha 1 Lucerne is suitable for under-sowing cereals. Being highly winter active, it establishes quickly and grows strongly through autumn, winter and spring. Sow it shallow at 1 to 2 cm with Group AL inoculant. Once the cereal comes off, you have a lucerne stand ready for grazing or cutting.

What lucerne recovers quickly after hard grazing or cutting?

We recommend Alpha 1 Lucerne, which shows vigorous recovery from cutting or grazing, an advantage in close-grazed pastures and intensive forage cutting programs. Its finer stems and higher leaf-to-stem ratio also mean higher protein and digestibility. Rotational grazing with rest periods still gives the best long-term persistence.

Is lucerne any good in a dry year on a dryland farm?

Lucerne's deep taproot helps it keep producing as conditions dry off. In a replicated independent dryland trial at Ballarat in Victoria, our Alpha 1 Lucerne was one of the best yielding varieties during extreme dry conditions. It suits dryland areas with 400mm+ rainfall, sown at rates matched to your rainfall.

Is lucerne safe for sheep and cattle to graze?

Yes, lucerne is excellent feed for sheep and cattle, and our Alpha 1 Lucerne has finer stems and a high leaf-to-stem ratio for higher protein and digestibility. Lush lucerne carries a risk of bloat in cattle and red gut in sheep, so introduce stock gradually and avoid turning hungry animals onto a fresh stand.

Alpha 1 vs Sceptre lucerne, which should I sow?

Choose Alpha 1 Lucerne for intensive grazing or cutting in 400mm+ rainfall, and Sceptre Lucerne for shorter 2 to 4 year cropping rotations, including drier country from 350mm. Both are highly winter active (rating 9) and can be sown from early winter to early spring. Alpha 1 offers fast establishment, finer stems and strong aphid and Fusarium resistance; Sceptre is an older, widely adapted variety.
