Reseeded swards have higher yields
Research at Moorepark has shown old pasture to yield on average, 3 tonne of Dry Matter (DM) /ha less than perennial ryegrass swards.
In Moorepark, pastures with 100% perennial ryegrass had February growth rates of more than twice those with 40% perennial ryegrass. The annual improvement in profitability is worth over €200 per hectare for the 100% perennial ryegrass sward.
