Cefalu (Trifolium vesiculosum) is an Annual Clover, which demonstrates early prostrate growth then becoming erect during the spring period and grows up to 1.2m tall. It produces thick stems with many tillers and large leaves which produce a distinctive “V” shape marking that is a characteristic of Arrowleaf Clover. Cefalu is deep rooted and can extend its root system up to 1.5m into the soil profile sourcing water from a perched water table. This will enable Cefalu to produce herbage long after traditional pastures have dried off and makes it a very valuable pasture where rainfall is likely to be insufficient for growth of various annual and perennial legumes.
Cefalu has excellent seed production ability and a high level of hard seed, which makes it well suited to long term cropping rotations. It has excellent tolerance to acid soils but will not tolerate extended waterlogging and thus heavy soils must be avoided. Arrowleaf Clover can be used for hay, silage or green manure. Its tall erect growth habit makes it well suited to grass/oaten hay mixtures. Cefalu can provide high feed quality (18-22% Crude Protein) and is ideal for hay, with excellent herbage production during the spring and early summer period.
This variety is registered under Plant Breeders Rights (PBR) in Australia. Unauthorised commercial propagation or any sale, conditioning, export, import or stocking of propagating material is an infringement under the Plant Breeders Rights Act (1994). Any breach of this legislation will leave the grower liable for prosecution.
Arrowleaf Clover is susceptible to Red Legged Earth Mite (Halotydens destructor) and control measures need to take place prior to sowing or soon after germination to ensure successful establishment. Cefalu is also susceptible to Root Knot Nematode (Meloidogyne spp.) although this is not common.
- Shows good early vigour
- Offers excellent winter and early spring production
- Adapted to a large range of soil types, especially lighter soils
- Suitable for grazing, fodder, green manure and High Density Legume mixes
- Excellent pioneering plant, especially on acid soil
- Due to its extensive root system, it can extract moisture and nutrients on deep acidic sands and utilise perched water tables – thus reducing the potential for worsening salinisation
- Due to its early maturity, Cefalu is suitable for grazing – using less moisture and producing similar amounts of herbage than other varieties of Arrowleaf Clover
No significant diseases have been known to occur. Clover Rot (Sclerotinia trifoliorum) can occur in dense swards in wet winters and the risk of Phytophthora Root Rot (Phytophthora megasperma) following virus infections can be increased.
Cefalu is a very hard seeded annual that is well suited to long term cropping rotations. It will not require re-sowing should appropriate management be undertaken. To maximise seed set in the year of sowing to ensure regeneration and long term persistence, stands should not be grazed during the flowering period. In established stands, light grazing can continue during the flowering period but should be avoided to ensure persistence. Once seed set is completed, plant residues should be either removed or grazed during late summer to promote better seedling regeneration.
Grazing during early establishment needs to be carefully monitored, as plant growth is not overly vigorous during the winter period. Once plants have established, spring production is vigorous and grazing pressure can be increased.
