Effects of seed coating on establishment and survival of grasses, surface-sown on tussock grasslands

Abstract
Perennial ryegrass, cocksfoot, and Yorkshire fog seeds, coated with various minerals, fungicide, and insecticide, bonded with an acrylic-type resin, were surface sown on existing vegetation in late winter on subxerous, dry hygrous. and hygrous sites at about 600 m altitude in the fescue tussock grasslands of the Mackenzie Country. Coating treatmenis were superior to uncoated seed. some coatings increasing seedling establishment two- to fourfold. No specific-coating effect was isolated.
