Zulu II

Arrowleaf Clover

  • Excellent spring and early summer growth
  • Erect, narrow stemmed variety
  • Well adapted to loamy and deep acidic sandy soils
  • Taproot can lower perched water tables
  • High level of hard seeds ensures good regeneration

    Description:

     

    Zulu II (Trifolium vesiculosum) is an Arrowleaf Clover of mid season maturity, which demonstrates early prostrate growth then becoming erect during the spring period and can grow up to 1.2m tall. It produces thick stems with many tillers and produces large leaves which produce a distinctive ā€œVā€ shape marking that is a characteristic of Arrowleaf Clover. Zulu II is deep rooted and can extend its root system up to 1.5m into the soil profile which can source water from a perched water table. This will enable Zulu II 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 annuals and perennial legumes. Zulu II 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. Zulu II can provide high feed quality (18-22% Crude Protein) and is ideal for hay, with excellent production during the spring and early summer period and provides a low bloat risk for cattle.

     

     

    Maturity:

     

    130 days

     

    Pest Resistance:

     

    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. Zulu II is also susceptible to Root Knot Nematode (Meloidogyne spp.) although this is not common. 

     

    Key Benefits:

     

    • The main benefit of incorporating Zulu II into sub clover based pastures is that the grazing phase in the spring can be extended by 4-12 weeks
    • As a standing feed, Zulu II makes ideal cattle feed due to its tall erect habit and low incidence of bloat. Sheep will also find Zulu II very attractive

     

    Disease Resistance/Tolerance:

     

    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.

     

    Variety Management/Agronomy:

     

    Zulu II 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 and 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.

    Annual Ryegrass

    Annual ryegrass is generally sown for a high quality short-term winter crop, providing multiple grazings in winter and spring. It is generally used for 6-9 months prior to sowing a summer crop, or to make the most of a growing season rainfall where late season rain is unreliable.
