Forage Sorghum

  • Ultra late flowering Sorghum x Sudan hybrid
  • Fine stemmed with high leaf to stem ratio
  • Provides large levels of high quality forage for extended periods
  • Ideal for early grazing
  • Excellent option for both intensive and extensive grazing management
  • Well suited to hay making
  • Prussic acid levels are low but caution should be used when Silo is in early growth or in a stressed condition

    Being a sorghum x sudan cross, Silo exhibits excellent hybrid vigour. Its ultra-late maturity enables many weeks of high quality leafy growth. Silo forage sorghum will not initiate flowering until daylight hours are less than 12 hours and 20 minutes, meaning it will remain in the vegetative stage, still producing large amounts of quality leaf for longer.



    Silo will provide a huge bulk of feed for the whole summer season, and can be made into hay, intensively or extensively grazed. Silo will provide high yields of quality forage and is ideal for extended grazing and cutting. It is also suited to all areas and climates subject to reasonable agronomic conditions and practices. With good management and sufficient moisture, Silo will provide excellent regrowth and multiple cuttings or grazings through until winter. Silo is a preferred option for early grazing, haymaking and round bale silage. It is also well adapted to pit silage production. 


    Disease Resistance/Tolerance:

    Silo does not require any varietal specific disease management considerations. However when considering broader disease management, please consult extension agronomists from various state government departments or experienced commercial agronomists / consultants in the relevant growing areas.


    Pest Resistance:

    Regularly monitor Silo for chewing insects and sucking pests like aphids, particularly early in its life.


    Variety Management/Agronomy:

    Sow forage sorghum into either a well prepared, fine, weed free seed bed, or via a no till system ensuring good seed/soil contact. Seed should be sown no deeper than 5cm. The use of a press wheel or roller is recommended to improve seed soil contact and establishment.


    If grass weeds are likely to be present, consider the use of S-metolachlor herbicide (Dual Gold®) for improved weed control. Seed must be treated with Concep II® Seed Safener prior to planting to prevent seedling damage. If broadleaf weeds are a concern, consider such chemistry as atrazine or fluroxypyr (Starane™). When contemplating herbicide options, remember to factor in plant back periods applicable to following crops and pastures.
