Jivet Tetraploid Annual Italian Ryegrass
Lolium multiflorum / westerwolds
The flowering date of Jivet is +18 days longer than tetila and +4 over Winterstar which offers additional feed and higher dry matter production late into the season.A longer growth period allows for additional milkings and stock carrying capacity.
- Jivet is a late maturing Tetraploid Ryegrass
- It is an excellent option in good dryland or irrigation ground where the extension of spring summer growth is required
- Rapid establishment & winter activity
- Jivet has the ability to respond to late season rainfall where most ryegrasses will not continue
- Exceptional Feed quality making Jivet one of the highly sourced products for top end farming systems
- High Animal Performance
- Excellent rust and disease tolerance for areas where typical ryegrasses struggle under climatic pressures

Plant Description
Plant: Annual.Leaves: hairless; blades up to 400 x 12 mm; young leaves rolled in bud.
Seedhead: spike up to 30 cm long; spikelets edge-on to the rachis which is recessed opposite each spikelet; 10-20 florets/spikelet, laterally flattened up to 25 mm long. Straight, fine awn up to 10 mm.
Seeds: ~230,000-250,000 tetraploid.
Pasture type and use
Short term pasture and high-yielding silage/hay crop.Where it grows
Rainfall: >600mm +Soils: Medium-heavy texture; high fertility.
Temperature: Cold tolerant.
Establishment
Companion species:Grasses & or cereals: Annual ryegrass & forage cereals.
Legumes: Medic, red and Persian clovers.
Other: Forage brassicas.
Sowing/planting rates as single species: 20-30 kg/ha.
Sowing/planting rates in mixtures: 10-15 kg/ha.
Sowing time: Autumn.
Fertiliser: P and N.
Management
Maintenance fertiliser: Especially P and N.Grazing/cutting: Well suited to fodder conservation. Strip or rotational grazing facilitates efficient utilisation and maximum regrowth. Graze at 2_ -3 leaf stage.
Ability to spread: Will spread from seed; seed set will occur if ungrazed/not cut and this will be associated with a substantial trade off in nutritive value.
Weed potential: Low unless allowed to set seed.
Major pests: Red and black-headed cockchafer, black field cricket, white-fringed weevil, African black beetle, corbies, underground grass caterpillar.
Major diseases: Rust.
Herbicide susceptibility: Glyphosate.
Animal production
Feeding value: High.Palatability: High and usually higher for tetraploid cultivars.
Production potential: High winter growth; rapid spring growth pre-flowering early summer.
Livestock disorders/toxicity: The ryegrass endophyte (Neotyphodium lolii) is not present in Italian ryegrass.
