Jumbuck Perennial Ryegrass
Lolium perenne - SKU:
A mid-season, diploid perennial ryegrass bred for high input grazing systems.
Maintains grazing value into summer
Produces outstanding liveweight gains
Ideal component for perennial pasture blends
- Diploid perennial ryegrass
- Designed to persist onwards of 5-7 years under suitable conditions
MaturityA mid season flowering variety designed to run later into the season than traditional diploid perennial types.
Days to flowering relative to Nui (0) = +0
Area of Adaption
- Medium to high rainfall and irrigation
- Best suited to regions with a cooler finish and reliable spring rainfall
- High temperatures can constrain summer growth
Soil TypeJumbuck is well adapted to a wide range of fertility levels and soil profiles, but peforms best in a well-drained loam. Diploid perennials will cope with short-term water-logging provided the growing tip is above water. To maximise stand productivity, soil testing is advisable. Analyse soil and neutralise deficiencies with fertiliser and/or lime.
FertilityGood base rates of phosphorus are necessary for maximum DM production especially during establishment phase. DM production is directly related to nitrogen availability. Consult your Upper Murray Seeds agronomist or fertiliser advisor for nitrogen application rates.
Sowing GuidelinesSow at 20-25kg/ha alone or 5-15kg/ha when a component of a pasture blend. Sow seed no deeper than 1cm in a fine but firm seed bed. Sow into bared ground if direct drilling. Lightly harrowand roll to improve germination. Suitable for oversowing into an established stand. Pasture productivity is directly related to successful plant establishment.
Disease and Pest ManagementDuring emergence it is essential to monitor regularly for damage from insects such as RLEM and lucerne flea, and spray as required. Inspect during early stand life for populations of black-headed cockchafer and slugs. Contact your Upper Murray Seeds agronomist for spray application rates.

Weed ControlJumbuck seedlings germinate quickly and are very competitive once established. Always use a knockdown herbicide to ensure you are sowing into a clean seedbed. Monitor for post-emergent weeds and spray as required. Use options such as spray-grazing for broadleaf weeds.
GrazingDo not graze Jumbuck until the plant is well anchored and root depth is established. Carry out a quick in-paddock ‘grab test’ by hand to ensure stock cannot pull plants out of the ground. Jumbuck should be rotationally grazed to maintain 2-3 leaves per tiller. If the stand is allowed to grow beyond the three-leaf stage, it may run to head earlier and there will be a proportional reduction in quality and productivity.
Remove dry residues from established stands during autumn to encourage new tillers and reduce stocking rates during late spring to encourage seed set and provide summer feed. Perennial ryegrass should be rested if temperatures exceed 30 ̊ C to reduce plant stress. Requires rotational grazing for persistence, high yields and to maintain nutritional quality.
Feed QualityMid-flowering diploid perennials provide good winter production extending well into spring. Jumbuck is an excellent base for any perennial pasture providing reliable DM production and hay production opportunities.
