(Trifolium Yanninicum)

irwin_hunter_seeds_trikkala_sub_cloverTrikkala is a white seeded mid-maturing sub clover variety. It is a prostrate self-regenerating annual pasture legume that is tolerant of waterlogging and heavy grazing. It grows from autumn through to spring and buries its burrs.

It is suited to medium to heavy acidic soils receiving a minimum 450mm/year rainfall. Trikkala is performs well on flood plains, and in irrigated environments.

It is a soft seeded variety and has very low levels of hard seed but shows good winter and early spring vigour. Vigorous seedlings provide good winter feed.

Very persistent in high rainfall areas and other areas. Adapted to soils prone to winter waterlogging. 112 Days To Flower

Trikkala is best suited to sheep, beef cattle and horses. It is good for hay and Silage

The limitations of Trikkala is that it has poor persistence on well-drained sandy soils.
It is suited to permanent and semi-permanent pastures and to crop rotations where cropping is infrequent. It has insufficient hard seededness for persistence in tight cropping rotations such as 1 year crop; 1 year pasture.
It is susceptible to germination following false breaks.
Being shallow-rooted, it is unable to capture deeper soil moisture and susceptible to premature death in dry springs.

Growing conditions:

Rainfall: Annual rainfall should be around 425 -1200 mm. Can also be grown under irrigation.
Soils: Prefers sandy loams to clays of moderate acidity (pH CaCl 4.5-6.5) and good water holding capacity. Highly tolerant of winter waterlogging.
Temperature: Good frost tolerance.
Companion species: Balansa clover, Gland clover, Persian clover, Purple clover, Burr medic. On paddocks with patches of well-drained soils it can also be sown with subterranean clover (black-seeded sub clover) and lucerne.
Sowing time: Sow April-June, shallow sowing into moist soil following good weed control.
Palatability: Readily consumed by livestock, either as green or dry feed.
Livestock disorders/toxicity: Some older varieties of subterranean clover contain high levels of phyto-oestrogens, which can affect the sheep reproductive system. The most active isoflavone is formononetin, which can cause a decline in ewe fertility. Formononetin levels drop away during late flowering. Generally, dry subterranean clover pastures that result from normal haying-off are not oestrogenic. All recently released varieties have low formononetin levels.
