    Mawson is a new early, Brachycalycinum type sub clover bred in Australia by SARDI. Mawson is suitable for long term permanent pastures in low-medium rainfall environments. Mawson has excellent long term persistence by regenerating through having higher levels of hard-seed (43%) and better seed production than other similar maturity varieties. Mawson has an intermediate growth habit with an early maturity, approx. 88 days to flowering (SA).

    Variety Management / Agronomy

    Sowing rate: (Dryland) 2 – 6kg per hectare in a Pasture mix or blend. As a lone stand sow at 6 – 10kg per hectare.

    Seed bed preparation: It is recommended to sow following the autumn break into a fine, well prepared seed bed. Seed should be sown with a starter fertilizer and the correct inoculant applied to the seed. Alternatively AgriCOTE coated seed can be used which includes inoculant, fungicide, micro nutrient’s and bio stimulants to enhance germination.

    Sowing: Best results are achieved by direct drilling Sub Clover into the top 1 – 1.5cm into a fine seed bed, press wheel’s or light rolling will assist establishment in most cases. This should be avoided if the soil is hard setting.

    Weed control: As sub clover is sensitive to some post emergent broadleaf weed until established, good pre sowing weed control is vital. Please seek the advice of your local agronomist to ensure satisfactory results.

    Pest & Disease Tolerance

    As with most small seed species, establishment pests such as RLEM, Lucerne Flea and Cockchafer can be a problem. Heritage Seeds recommends the sowing of AgriCOTE Mawson that contains Gaucho seed treatment to provide some resistance to insect pressure during initial establishment. Monitoring of insect pressure and disease (especially during establishment) should be practised, and contact your local agronomist for control advice.



    Mawson has proven to be a top-yielding early sub clover that will significantly out-yield the common variety Dalkeith. 




    Sub Clovers

    Sub clovers are amongst the most widely used pasture legumes in southern Australia. They are typically used in low-medium, winter rainfall dominant areas for extensive grazing operations. The term sub clover refers to a group of three species:

    Subterraneum, Yanninicum & Brachycalycinum.
