Sowing & Establishment
Delish tetraploid short rotation ryegrass seed is heavier than diploid seed, so ideally should be sown at a 40% higher rate than diploid cultivars. Sow at a minimum of 22 kg/ha in a mix with Superstrike treated clover, or added to a perennial pasture mix such as Base tetraploid perennial ryegrass at 4-7 kg/ha. In an undersowing situation, sow Superstrike treated seed at 14 kg/ha. Delish performs best on sites with reasonable soil moisture and medium to high fertility.

As with all grasses, overgrazing of Delish tetraploid short rotation ryegrass should be avoided. Given the higher palatability of Delish, stock may graze it to lower residuals than diploid ryegrasses.
