Winter Star II tetraploid annual ryegrass is suitable for quick winter feed with improved spring quality, making it ideal for silage and hay production. Winter Star II is high yielding with fast establishment giving excellent autumn growth. As a tetraploid, Winter Star II also has excellent feed quality.
It is recommended that a rotational grazing system be used when feeding Winter Star II tetraploid annual ryegrass, to allow improved regrowth following grazing.
Winter Star II tetraploid annual ryegrass should be sown alone at a minimum of 25 kg/ha, using higher rates for more winter feed, or at a minimum of 14 kg/ha using Superstrike® treated seed in an undersowing situation.
Pasture Life: 6-9 month option

“Winter Star II on the milking platform has given us options to make more silage that is better quality than previous years. It keeps growing well into August and September and maintains its quality, enabling us to turn low producing paddocks into high performing paddocks within 12 months. The extra production has certainly paid for the cost of the seed.”
