Soil TypeGrows well on a wide range of well drained soils including deep loams, sands, loam over gravel or clay but does not produce as well on shallow soil types. Silverado has improved acid soil tolerance although it is highly recommended to lime prior to sowing. All lucernes are sensitive to high aluminium levels common in low pH soils. This reduces root development and hence plant productivity.
FertilityMature Silverado will benefit from annual phosphorus and potassium applications, especially if removing hay/silage from the paddock.
Sowing GuidelinesLucerne can be established successfully whether it is sown in autumn, winter or spring. The time of sowing normally depends on the rainfall and climate of the region. Autumn establishment is better suited to winter active or highly winter-active varieties as they have better frost tolerance. Delayed sowing allows the opportunity to improve weed control and seedbed preparation. For spring established lucerne aim to sow mid August onwards as the soil temperature begins to increase and daylight increases.
Sow the seed at 4-8kg/ha (dryland) or 15-25kg/ha (irrigated) at approximately 1cm depth. Lucerne seed must be inoculated with the AL strain of rhizobium to ensure effective nodulation and prompt establishment.
Do not sow into an “old” lucerne stand. Allow a minimum of three years between stands to create an effective disease break
Disease and Pest ManagementMonitor regularly during emergence for insect damage from pests such as RLEM, aphids and lucerne flea and spray if required. Silverado is highly resistant to spotted, blue-green and pea aphid species. It also has good levels of resistance to nematodes (eghighly resistant to root-knot, resistant to root-lesion and moderately resistant to stem nematode).
Phytopthora root rot, Anthracnose and Fusarium crown rot can severely damage lucerne however Silverado has high resistance levels to these diseases.

Weed ControlSpray out any old pasture/crops with glyphosate prior to sowing but speak to your Upper Murray Seeds agronomist about the correct rate to use depending on the size of weeds present. Also consider using a pre-emergent herbicide such as trifluralin.
Weed control in young lucerne can be challenging due to its slow seedling growth. Most broad-leaf herbicides cannot be applied until the lucerne is at the third trifoliate leaf stage. Weeds need to be treated when small. Once a stand is established (>1 year) there are more winter cleaning options and herbicide efficacy is improved.
GrazingAllow the stand to reach approximately 20cm high and ensure that the plants cannot be pulled out prior to grazing. Allow lucerne to flower in its first year so the plant can strengthen its crown and taproot.
Monitor the first grazing carefully and remove stock before they begin to graze near the crown of the plant. Rotational grazing (or strip grazing) is essential for productivity and longevity of the stand. Lucerne can withstand set stocking during spring provided sufficient moisture is available. Avoid damaging the crown of the lucerne plant.
Feed QualitySilverado is highly regarded due to its ability to produce top quality, out-of-season feed. It has a high leaf:stem ratio, excellent palatability and digestiblity. Silverado has good levels of metabolisable energy and is a reliable source of crude protein.
