Concord® II is an outstanding Italian ryegrass with exceptional speed of establishment. It delivers increased winter production and solid seasonal dry matter production with the ability to carry through to the second year where conditions allow.
Sow with other ryegrasses and clovers to maximise forage opportunities and fix free atmospheric Nitrogen from the clovers.
Sowing rate (sole): 20-35kg/ha
Sowing rate (mixed): 15-20kg/ha
The breeding background for Concord II had a focus on seedling vigour which is a very important trait for the Australian environment. Seedling vigour has certainly been achieved, especially when compared against the original Concord.
While many Italian ryegrasses sold in Australia have generally achieved good seedling vigour, the persistence has certainly been questioned by Australian farmers, however the breeding of Concord II has demonstrated good regrowth into the second season given favourable conditions. This combination will change the thinking of Australian farmers about the persistence of fast establishing, Italian ryegrass.
Concord II is a diploid, so sowing rates should be between 10-35kg/ha using Ultrastrike® seed treatment. Sow as early as possible to maximise winter feed in the first year and monitor fertility levels to optimise production.
Test the plants for anchoring approximately 40-45 days after sowing as a light grazing as early as possible will aid tillering and further root development. This will result in increasing overall productivity and the plants ability to withstand stress periods such as dry periods during the warmer months of the year.

Concord II is best suited to rotational grazing as this allows the plant to recover as quickly as possible. Concord II should be sown as soon as there is adequate moisture which will maximise the winter production of the product. A light grazing as soon as the plants can withstand pulling will encourage tillering as well as growth of other species such as clovers if they have been sown with Concord II.
To get the most out of Concord II, graze as soon as the plants have reached the third leaf growth stage to ensure that the best quality is achieved. Ensure you test the plants before allowing stock to graze the paddock otherwise this may cause significant damage to the newly sown pasture.
For best persistence and to give Concord II every opportunity to survive into the second year, avoid hard grazing over the summer months. Concord II can be used to increase the winter production of a pasture because of its seedling vigour and its ability to persist into a second year.
Recovery of the plants will be determined by how much residual is left after the grazing period. Avoid grazing to bare ground as this will significantly slow down recovery after grazing and will be detrimental to the overall production of the ryegrass over the growing season.
Concord II has been trialled and screened for rust during the selection process. To ensure that Concord II is protected from insect attack at the early establishment stage, Ultrastrike seed treatment is recommended. Ultrastrike seed treatment offers protection against some of the common pasture pests such as Red Legged Earth Mite and Blue Oat mite. The protection is only for 6 weeks, so it is still important to monitor the pasture and especially soon after sowing so that any management requirements are implemented as soon as necessary.
