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.
Concord® II is the next generation Concord®, which was the first proprietory ryegrass released in Australia by PGG Wrightson Seeds.
The speed of establishment of Concord® II allows for greater flexibility of the variety, allowing it to be used in many more situations than its predecessor. While traditional autumn sowing is the primary use of Concord® II, its speed of establishment allows it to be used successfully in over-sowing situations, pugged pasture recovery programmes, spring sowing where irrigation is available or where Italians have been used in a more annual sowing programme.
When used in an autumn sowing, the increased growth through the winter months is where Concord® II will return the greatest benefits to your farming situation by delivering excellent feed volumes to support grazing animals.
Another improvement that has been made with Concord® II is increased second year production which has been a trait that other Italian ryegrasses, coming to the market seem to have lost over the past few years.
Concord® II has been developed over many years to ensure that we delivered significant improvements to the original Concord®. Concord® II has been bred by PGG Wrightson Seeds in Australia under Australian conditions.
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 10-30kg/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.
