A shortened version of the URL, helpful when communicating the URL over email or verbally. Species & Varieties. Isohyets show average annual rainfall (mm) for stations with more than 20 years of records.
This is due in part to their greater tolerance of low levels of available zinc, a common feature of such soils, but also due to their burr burial characteristics. Gosse over all test sites and seasons, suited to 450-700 mm mean annual rainfall areas, 27% more biomass than cv.
Most sub clovers prefer slightly to moderately acid soils, pH(CaCl2) 5.0–6.0.
With enough fertiliser and sound management, these stands contribute to farm profit by: The >most important characteristics to consider when choosing which variety to sow are: Table F1 lists the characteristics of current sub clover varieties.
Varieties that set enough seed to persist well along the drier western fringe of the clover belt in NSW are those that mature earliest. Hard seeds are impermeable to water and will not germinate until the seed coat becomes permeable. Please note: This content may be out of date and is currently under review. %%EOF
Now refer to Table F2 below for the selection of sub clover variety according to the climatic zone.
675 mm or greater: Neutral to alkaline soils: Clare, 700 mm or greater:Junee, Seaton Park LF, York, Coolamon, Waterlogged areas only:Riverina, Trikkala, 450 to 500 mm:Dalkeith, Urana, Seaton Park LF, Coolamon, Junee, Trikkala, and Riverina in waterlogged areas only, Greater than 600 mm:Seaton Park LF, Junee, Gosse, Riverina, Goulburn, Denmark, Leura, Greater than 800 mm:Leura, Denmark, Gosse, Greater than 700 mm:Riverina, Goulburn, Junee, Denmark, Leura, Gosse, For coastal forage crops:Clare, Woogenellup, As a winter forage crop, Illawarra only: Clare. Dalkeith over all test sites and seasons, suited to 550-900 mm mean annual rainfall areas, of the yanninicum subspecies and suited to waterlogged soils, resistant to clover scorch, leaf rust and Phytophthora root rot diseases, 15% more biomass than cv.
Burr burial can also influence seed size and the rate of hard seed breakdown. Clare, Rosedale, Antas and Nuba are varieties of the subspecies brachycalycinum.

Choose a variety that flowers and completes seed development before soil moisture runs out, which usually occurs in spring. >Only varieties that have a low or very low formononetin content should be sown.
For high seed yields, good soil moisture is needed for 10 weeks from the start of flowering. These eventually cause the seed coat to split. In >northern NSW, hardseededness is less important, as softer seeded varieties may germinate on summer rain and survive until more reliable growing conditions in late autumn. Hard seed also provides a bank of seed capable of germinating after a year when seedset has failed or has been very poor. 1530 0 obj

For further information on subterranean clover, see the other sections of this Agfact: Figure F1. Six new subterranean clover varieties have been developed from a national five-year joint venture between the Department of Primary Industries and Regional Development (DPIRD) and pasture seed company, Seed Force.
Hard seeds break down most quickly during hot summers, particularly if held in burrs on the soil surface. The >most important characteristics t…
Superior low-oestrogen varieties are readily available (see Table F1). But these late varieties may fail to set seed in dry environments or if rainfall in late spring is inadequate. Subterranean Clover. Clover disease is caused by moderate to high levels of the oestrogenic plant substance >formononetin, and is an important cause of infertility in sheep.
Persistent varieties set enough seed each year to produce a dense crop of seedlings the following autumn. 0

Each year in New South Wales, clover disease costs the sheep industry over $2 million.
Flowers are produced over a period of about 6 weeks, sometimes longer in good seasons. Subterranean clover (sub clover) is native to the Mediterranean and the Near East and well-adapted to areas with relatively warm moist winters and dry summers. Hard seed breakdown is slower where there is a large amount of surface residue, and in cooler tableland environments. They grow better on neutral to alkaline soils and grey, cracking soils than other sub clover varieties. juillet 2020 . Close grazing until the onset of flowering encourages burr burial, while lenient grazing, which allows the stand to become very leafy, results in a higher proportion of burr being set on the soil surface. Biserrula pelecinus . The joint venture aimed to bring new and innovative sub-clover legume traits to the national and international agricultural market for the ongoing benefit of the Western Australian agriculture industry and elsewhere. Varieties which belong to the yanninicum subspecies that have cream or light brown seed, such as Trikkala, Gosse, Riverina, Larisa, Napier and Meteora (which are low in dangerous oestrogens) and Yarloop (highly oestrogenic), are better adapted to waterlogged or poorly drained conditions than other sub clover varieties.
Subterranean Clover is an extremely valuable self-regenerating annual clover.

producing an abundance of high-quality feed for livestock; produce less feed from thin or patchy stands; make little contribution to improving soil fertility. Short-season hard-seeded varieties are essential for persistence. Flourishes in Australia when grown from bulk clover seeds, used as a rangeland legume in Western Oregon and California.
Late-maturing varieties produce the most feed in spring, but they need a lot of soil moisture late into spring. Recommended for the acid brown and red earth soils only. During summer, some of these hard seeds ‘break down’ (become soft or permeable to water) in response to high temperatures and day–night temperature fluctuations.
