What sub clover will survive in a paddock that gets waterlogged every winter?
We recommend Riverina Subterranean Clover. It belongs to the waterlogging tolerant yanninicum subspecies and has high levels of resistance to phytophthora root rot, clover scorch and powdery mildew. It can be sown across a wide range of soil types, suits 425mm+ rainfall and has a good fit across the South West, at pH 4.5 (CaCl2) or higher.
Which clover is best for the medium to high rainfall South West?
Riverina Subterranean Clover is regarded as one of the most versatile sub clovers for medium to high rainfall areas in WA. It was trialled at Wokalup and Vasse and fits well across the South West. It is a mid-season, white-seeded variety with high forage production and good hard seed levels.
How much Riverina sub clover should I sow?
We recommend 20 kg/ha of Riverina Subterranean Clover when sown on its own and 6 to 8 kg/ha in a mix. Inoculate with Group C rhizobia before sowing. It is suited to early watering programs, so it also works well where irrigation starts early in autumn.
What clover resists clover scorch and powdery mildew?
Riverina Subterranean Clover resists Race 1 clover scorch and is at least moderately resistant to Race 2. It also has more resistance to powdery mildew than Gosse, and better tolerance of leaf rust and leaf spot. It has high levels of resistance to phytophthora root rot too, and withstands waterlogging.
I want more autumn and winter clover feed than my old Trikkala pasture gives, what should I sow?
We suggest Riverina Subterranean Clover. It produces more autumn and winter feed than Trikkala, has more hard seed and lower levels of the oestrogen formononetin. It withstands waterlogging and flowers about 122 days after sowing in Perth, a little later than Trikkala.
Is there a sub clover with low oestrogen for breeding ewes in wetter country?
Riverina Subterranean Clover has lower levels of the oestrogenic compound formononetin than Trikkala, which makes it a better option for breeding ewes. It belongs to the waterlogging tolerant yanninicum subspecies and has high resistance to phytophthora root rot, clover scorch and powdery mildew. It suits medium to high rainfall areas, 425mm or more.
How long does Riverina take to flower?
Riverina Subterranean Clover flowers about 122 days after sowing in Perth, which puts it in the mid-season maturity group, suited to medium to high rainfall areas. Its hard seed levels are higher than Trikkala and Gosse, which helps it regenerate and increases production in the following years.
What clover should I sow on wet, acidic flats near Harvey or Busselton?
Riverina Subterranean Clover suits wet, acidic flats. It tolerates waterlogging, grows at pH 4.5 (CaCl2) or higher, suits 425mm+ rainfall, can be sown across a wide range of soils and has a good fit across the South West. Sow it with a ryegrass such as our Victorian Perennial Ryegrass for bulk, and inoculate with Group C inoculant.
Will a white seeded sub clover keep coming back each year?
Yes. Riverina Subterranean Clover is a white seeded (yanninicum), self-regenerating annual with hard seed levels higher than both Trikkala and Gosse, which increases the potential for production in following years. It withstands waterlogging and has high resistance to phytophthora root rot, clover scorch and powdery mildew, suiting medium to high rainfall areas.
Riverina vs Urana sub clover, which one should I use?
Choose Riverina Subterranean Clover for wet, waterlogging-prone paddocks in medium to high rainfall areas, as it is waterlogging tolerant and resists root rot. Choose Urana Subterranean Clover for well-drained soils in 400mm+ rainfall areas, where its strong winter activity and early flowering shine. Both need Group C inoculant.
