SARDI Grazer Lucerne

Contact us

SARDI-Grazer was developed through a GRDC funded project aimed at increasing the persistence of lucerne in mixed grazing/cropping systems, where large paddocks limit the use of rotational grazing. It has proven to be the variety of choice across all enterprises where less than ideal grazing management occurs. SARDI-Grazer is well suited to permanent pastures systems in the medium to high rainfall areas, where long periods of continuous grazing (over four weeks) by sheep or cattle is common practice.

Key features
• Market leading grazing tolerant lucerne variety
• Persists under periods of set stocking up to two months once established
• Winter activity rating 6 (6.5 effectively)
• Requires minimal rotational grazing management
• Broadly adapted to a variety of farming systems

Key benefits
• Persistence 8–10 years+
• Exceptional persistence across a range of environments from low to high rainfall, dryland and irrigation
• Well suited to mixed swards with perennial grasses such as winter active tall fescue, cocksfoot or phalaris

• Dual purpose grazing and/or hay where grazing duration will at times be greater than 30 days
• Mixed cropping systems where lax grazing and persistence is required

Product fit
SARDI-Grazer is an ideal fit for:
• Wool, prime lamb and beef production areas with medium to high rainfall, where mob sizes and numbers prevent the use of strict rotational grazing.
• Cropping rotations where large paddocks restrict the use of rotational grazing.
• A long-term lucerne stand; where a permanent pasture with volunteer grasses or mixtures with phalaris, cocksfoot or tall fescue is required.
• Any system where a simple two paddock rotation system is required for managing livestock.

Agronomy and management
SARDI-Grazer is a winter active cultivar that has been bred to withstand spells of continuous grazing of up to two months. To gain sound establishment the crop should only be lightly grazed in the first year, as per all lucerne varieties. Once established, it can be grazed in a two paddock rotation with 6–8 weeks grazing followed by 6–8 weeks recovery. The recovery period is critical for recharging energy reserves of the plant which will maintain excellent levels of production and persistence.
SARDI-Grazer can also be recommended for any grazing enterprise, as the results from New South Wales, Victoria and South Australia show exceptional persistence under management practices currently used on commercial farms. Lucerne may be suitable for planting in soils with lower pH levels, provided exchangeable Aluminium levels are very low. A reliable soil test and advice from an agronomist is strongly recommended.
