Discover the Stamina® range and NEW Torrens GT8 and Warrego GT6 grazing tolerant lucerne.

Stamina grazing tolerant lucerne - Premium quality hay and TRUE grazing tolerance. The Stamina range of modern lucernes provide a higher return on investment (especially after 3 years) in comparison to older cultivars such as Aurora. 

Lucerne trial analysis: 2012 - 2020 grazing tolerant trial Leigh Creek, VIC

Trial protocal

Graph shows the 2012 sown dryland grazing tolerance trial at year 2, 3 and 8. This trial was continuously grazed for six months at 50 sheep per hectare equivalent from January 2014 through to June 2014, and repeated again from January 2015 until June 2015. All cultivars were trailed under the internationally recognised Standard Test Protocol for grazing tolerant lucerne.

NEW Torrens GT8: Lucerne trial analysis

NEW Torrens GT8 grazing tolerant lucerne (of the Stamina range)

Torrens GT8 had higher ground cover in years 2 and 3 compared to all dormancy 7-10 varieties and some dormancy 6 varieties. Torrens GT8 also maintained 40% ground cover after 8 years of hard grazing.

  • Torrens GT8 ground cover was 40.8% higher than Aurora after the first set stocking period in 2014
  • Torrens GT8 had a ground cover percentage of 62.5% after 2 years of the grazing tolerance trial continuing as a viable lucerne stand
  • After 8 years Torrens GT8 remained a standout in the highly winter active category maintaining a ground cover of 42%, demonstrating a viable dryland lucerne stand in comparison to other highly winter active varieties
  • Torrens GT8 a Stamina grazing tolerant lucerne, had higher ground cover in years 2 and 3 compared to all dormancy 7-10 varieties and some dormancy 6 varieties

Torrens GT8 grazing tolerant lucerne: Grazing tolerance and winter activity - the ultimate combination.

Torrens GT8 is the first grazing tolerant, highly winter active lucerne to be released to the Australian market that has been trialled under the Internationally recognised Standard Test Protical for grazing tolerant lucerne. 

By combining winter activity and grazing tolerance, Torrens GT8 provides flexibility not previously available. The low crown height offers protection to the plant from heavy grazing, high tyre traffic or hoof damage.

Stamina GT5: Lucerne trial analysis

Stamina GT5 grazing tolerant lucerne

  • Stamina GT5 is a true standout for grazing tolerance and persistence. After 2 consecutive years of the grazing tolerance protocol and another 6 years of grazing, Stamina GT5 maintained the highest ground cover of all dormancy 5 varieties
  • Stamina GT5 ground cover remained extremely high at 76.7% after the first hard set stocking period, 50.9% higher than Aurora after 1 period of set stocking
  • After the second set stocking period in 2015, Stamina GT5 remained at 76% when measured in August 2015, showing its true grazing tolerance
  • When another ground cover measurement was taken in September 2020, after 8 years. Stamina GT5 had an impressive ground cover of 71.6%. During this time the lucerne trial had been managed normally and grazed when feed was available
  • Using Stamina GT5 lucerne with proven grazing tolerance and persistence, increases the amount of dry matter grown per hectare, provides longer lasting feed and increases your economic return compared to non-proprietary varieties such as Aurora and other non-grazing tolerant varieties

Stamina GT5 grazing tolerant lucerne: The ultimate choice for grazing tolerant lucerne

Stamina GT5 is a high performing lucerne variety that will produce quality hay and grazing opportunities for seven to ten years. It is a true grazing tolerant lucerne which has been trialled over many years under the internationally recognised Standard Test Protocol for grazing tolerant lucernes. Stamina GT5 lucerne is the ultimate choice where a stand is required for prolonged periods of set-stocking.

NEW Warrego GT6: Lucerne trial analysis

Warrego GT6 grazing tolerant lucerne

  • Warrego GT6 ground cover was 75% when measured after the first set stocking period in 2014 which is similar to other dormancy 5 varieties
  • After another six month set stocking period in 2015, Warrego GT6 maintained a ground cover percentage of 75% whilst other dormancy 6 varieties continued to decline
  • After 2 consecutive set stocking period in 2014/2015, Warrego GT6 had 60% more ground cover in comparison to Aurora

In comparison to older cultivars such as Aurora and after all cultivars were trialled under the
internationally recognised Standard Test Protocol for grazing tolerant lucerne, it was evident that:

  • When measured after the first set stocking period in 2014 Aurora (a non GT lucerne) dropped to 25% in ground cover rendering the stand unviable
  • Aurora continued to decline in 2015, dropping to 15% ground cover
  • With increased persistence, Warrego GT6 gives growers management flexibility, allowing them to decide when to terminate the stand in comparison to Aurora

Ultimately, the Stamina range of TRUE grazing tolerant lucernes featuring NEW Warrego GT6, Torrens GT8 and Stamina GT5 and are an ideal choice for farmers seeking a long term lucerne solution with a higher return on investment, compared to cultivars which decline significantly in ground cover after 2-3 years.

Warrego GT6 grazing tolerant lucerne: Improved persistance with Warrego GT6, the upgraded replacement to Stamina GT6

Trialled and tested over multiple environments and conditions, Warrego GT6 (of the Stamina range), is a monumental step up in grazing tolerance and persistence compared to older dormancy 6 varieties. Bred to persist for prolonged periods of set stocking, Warrego GT6 provides growers with grazing flexibility, high quality hay, persistence similar to a dormancy 5 and winter activity of a 6.
