Sowing quality seed with good equipment that can accurately place small seeds, as most perennials have, can contribute to good establishment at relatively low perennial species sowing rates. Lucerne, for example, has around 450,000 seeds (clean seed basis) per kilogram. Sowing at 2 kilograms per hectare will therefore supply around 90 seeds sq/m. Good quality seed at this sowing rate, sown into good moisture at 10 to 15 centimetre soil depth, normally can guarantee more than 20 plants sq/m.
