Warrego GT6 Grazing Lucerne

Warrego GT6 grazing tolerant lucerne is an improved persistance with Warrego GT6, the upgraded replacement to Stamina GT6.

  • Next generation dormancy 6 with TRUE grazing tolerance
  • Ultra-persistent under grazing with improved persistence over Stamina GT6
  • Low crown height offering protection from periods of set stocking and traffic tolerance
  • Good disease resistance package
  • High quality hay and grazing opportunities
  • Strong return on investment over the extended grazing lifespan

Description

Warrego GT6 grazing tolerant lucerne is an 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.

Lucerne trial analysis 2012 – 2020 grazing tolerant trial Leigh Creek, VIC

  • 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

Sowing and establishment

Identify an area to plant lucerne in, a minimum of 6 months prior to sowing. Correct paddock selection is a key driver for long term lucerne stand persistence. Lucerne will grow on a variety of soils, but does best on deep, well-drained soils of medium to light texture.

Seedbed preparation: Preparing the seedbed takes into consideration the soil type and cultivation of the soil to ensure the soil is fine but firm when sown.

Pasture seed sowing depth: Sowing depth needs to be managed as lucerne is a small seed and therefore only needs to be sown at no more the 15mm deep. This will enable the lucerne to germinate and the seedlings to rise above the soil to begin photosynthesis.

Grazing management

Warrego GT6 (of the Stamina range), should be grazed in a rotational grazing system. It is recommended that the rotation period is between 30 – 35 days following grazing during the growing period (rotation lengths may need to be extended during the cooler months due to slower growth). When grazing lucerne it is ideal to graze the plant down to 5cm in height and then have the stock taken out.
