Riverina Subterranean Clover

We recommend Riverina Sub Clover. It belongs to the yanninicum subspecies, which is tolerant of waterlogging, and it has high resistance to Phytophthora root rot, a common problem on wet soils. It suits a wide range of soils in the South West with pH 4.5 or higher.

Riverina Sub 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.

We recommend 20 kg/ha of Riverina Sub 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.

Riverina Sub 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. That makes it a reliable choice in wetter districts where these diseases are common.

We suggest Riverina Sub Clover. It produces more autumn and winter feed than Trikkala, has more hard seed and lower levels of the oestrogen formononetin. It suits wet soils and flowers about 119 to 122 days after sowing at Perth, a little later than Trikkala.

Riverina Sub Clover has lower levels of the oestrogenic compound formononetin than Trikkala, which makes it a better option for breeding ewes. It also tolerates waterlogging and resists key diseases. As with any clover, keep an eye on bloat risk if cattle graze lush, clover-dominant pastures.

Riverina flowers about 119 days after sowing at Perth according to our tech sheet, and our 2026 guide lists about 122 days. That puts it in the mid-season group, suited to areas with a longer growing season. Its higher hard seed levels help it produce well in the following years.

Riverina Sub Clover suits wet, acidic flats. It tolerates waterlogging, grows at pH 4.5 or higher and suits a wide range of soil types. It is well adapted to the South West. Sow it with a ryegrass such as our Victorian perennial for bulk, and inoculate with Group C rhizobia.

Riverina Sub Clover has good hard seed levels, higher than both Trikkala and Gosse, which helps it regenerate reliably and increases production in the following years. Ease grazing during flowering so it can set seed, and keep dry residue under control over summer so seedlings can establish.

Choose Riverina for wet, waterlogging-prone paddocks in medium to high rainfall areas, as it is waterlogging tolerant and resists root rot. Choose Urana for well-drained soils in 400mm+ rainfall areas, where its strong winter activity and early flowering shine. Both need Group C inoculant.
