It is the ideal option for high quality, medium to long-term pastures, in conditions suited to tetraploid ryegrass. The rapid establishment of Ohau also makes it ideal for under-sowing into older pastures. Ohau: is available with AR1, AR37 and LE endophyte Sow rate: 10-15 kg/ha in mixtures, 20-30kg/ha alone  ]]> Winter and spring production in a quality tetraploid ryegrass
Ohau is a unique tetraploid long-rotation ryegrass. Ohau has a late-heading date and was bred for high production and quality. Strong emphasis was placed on winter and early-spring growth.
Ohau has strong winter and early-spring activity, which allows it to contribute valuable growth in the critical early-lambing and calving period. Ohau is an extremely palatable grass, with a high feed value. Ohau’s palatability results in pastures with a high green leaf content over summer.
Ohau is the ideal option for high quality, medium to long-term pastures, in conditions suited to tetraploid ryegrass. The rapid establishment of Ohau also makes it ideal for under sowing into older pastures, with the AR37 endophyte offering increased protection against insect attack and increasing long-term benefits.
Features
  • Ideal for under sowing
  • Very strong cool-season growth
  • High-yielding ryegrass

 

]]> JETA https://seedscereals.co.nz/product/jeta/ Sun, 11 Sep 2016 22:07:13 +0000 http://seedscereals.co.nz/?post_type=product&p=3767 High performance long-rotation tetraploid ryegrass Jeta is a high performance long-rotation tetraploid ryegrass that combines the cool-season vigour of Italian ryegrass (20%) with the robustness of perennial ryegrass (80%). Farmers love the speed of establishment, rapid winter and early spring growth, palatability, utilisation, and excellent stock performance. It has also proven to have surprising persistence, even with dry conditions and intensive grazing. Jeta can be grazed with all animal types, and used as highly productive pasture for five or more years in climates suited to perennial ryegrass. JETA is available with AR1 endophyte Sow rate: 10-15kg/ha alone, 5-10 kg/ha in mixtures  ]]> Jeta is developed to combine strengths of perennial & Italian ryegrasses, particularly increased cool season growth and increased nutritive value (eg water soluble carbohydrates).
Plant Description
Hybrid Plant: Intermediate between perennial and Italian ryegrass species. Characteristics between cultivars depend on perennial : Italian parentage percentage.
Stems: 30-90 cm.
Leaves: Fine (~7 mm), dark green, hairless, under surface shiny, blade folded about mid-rib in young shoot, leaf-base usually dark red.
Seedhead: Spike ~20 cm, spikelet usually <10 florets/spikelet; awnless lemma.
Seeds: fawn, flat, awnless, ~6mm long. Approx 300,000/kg (tetraploid cvv) Tetraploid cvv: these have double the number of chromosomes, larger cells, leaves and seed.
Pasture type and use: Grazing and fodder conservation. Most widely sown pasture grass in temperate regions.
Where it grows:
Rainfall: > 700mm+.
Soils: Medium-heavy, moderate-high fertility (eg Olsen P >12, 0-10 cm). Tolerates slight salinity.
Temperature: Cold and frost tolerant, growth constrained by high temperature.
Establishment:
Companion species:
Grasses: Perennial ryegrass.
Legumes: white clover, medics and sub clover.
Sowing/planting rates as single species: 10-25 kg/ha.
Sowing/planting rates in mixtures: 5-10 kg/ha.
Sowing time: Autumn and spring.
Fertiliser: P & possibly N at sowing.
Management:
Maintenance fertiliser: requires fertile soil to persist. ~10 kg P/ha. Monitor S, K, Cu especially. Supply N by clover/fertiliser.
Grazing/cutting: Tolerates close, continuous grazing except if drought-stressed. Graze at 2.5-3 leaf stage to optimise yield under rotational grazing.
Ability to spread: Will spread if allowed to seed.
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: Crown rust, stem rust, barley yellow dwarf virus, ryegrass mosaic virus.
Herbicide susceptibility: In choosing selective herbicides consider the stage of growth of the ryegrass and what non-target companion species are present.
Animal production:
Feeding value: High nutritive value.
Palatability: Palatable.
Production potential: High yields; highly responsive to fertiliser and irrigation.
Livestock disorders/toxicity: Cultivars with wild endophyte can cause perennial ryegrass toxicosis and ill-thrift. Bacterial infection of seedhead can occasionally occur and result in ergot poisoning.
