A diploid perennial ryegrass which has been bred to suit a range of farming regions in southern Australia. Platform AR37 is a fine leaved, mid-late heading (+12) ryegrass with low aftermath heading enabling excellent pasture utilisation and quality late into the season. Platform’s late heading date combined with a dense fine leaf structure and low aftermath seed head, produces quality feed to assist with summer animal performance.
Characterised by high tiller density with peak growth between the mid season flowering types such as Rely/Excess and later flowering Expo/Base. Optimum performance is best achieved with rotational grazing but Platform can withstand periods of set stocking.
Platform was bred from elite Australasian genetics and north-west Spanish material and has undergone testing to ensure its adaptability across all ryegrass growing regions of Australia.
Platform has been bred, selected and successfully tested as a perennial and will function as a perennial ryegrass. Due to a small number of tip awns, Platform is certified as Lolium boucheanum.
Platform perennial ryegrass pasture seed can be sown at 15-25 kg/ha on its own or with proprietary clovers for increased animal performance. Sowing depth is important as is the seed to soil contact, given that Platform AR37 is a small seed. Ensure that the depth of sowing is between 5 and 15mm for optimum establishment rate and early vigour.
If the seed is sown too deep, then the seed will be delayed in its establishment which then has an impact on other important management decisions such as weed control and timing, insect pest management and grazing timing.

Platform perennial ryegrass will produce better under rotational grazing. Avoid hard set stocking during periods of stress (eg. droughts, low fertility and insect attack).
The first grazing should be a light grazing to encourage tiller development and secondary root growth. This shouldn’t take place until the plants can withstand the “pull test” which is a simple and fast way to identify if the plants have established well enough to handle grazing by an animal. The first grazing should be done with sheep or a light class of cattle and ensure that the ground is relatively firm, to minimise any potential damage that could be caused by the animals moving across the new pasture.
The first grazing is also a very important aspect of managing a newly sown pasture, especially if the pasture includes other species such as clover as it allows for light to be able to get down to the newly emerging clover plants for them to continue to grow and develop and be an integral part of the overall pasture for years to come.
Minimum 650mm rainfall per annum unless irrigated
I planted 16 Ha of Platform last year (2019) and the grass is still persisting and providing good quality feed throughout the season. I have found the AR37 endophyte is giving Platform excellent resistance to the bugs that have come onto the farm. I would recommend Platform as part of a dairy farming system as considering how hard I push the farm, we really need top notch grasses.
