Growing barley or oats in the year of forage establishment is a common agronomic practice in marginal growing regions, but is often not recommended to growers in Newfoundland. Spaner & Todd (2003) reported that barley seeded at rates of 100-150 kg seed/ha and undersown with a timothy-clover mixture (harvested at mid-milk) resulted in the planting year in greater forage yield of poorer quality than pure-stand timothy-clover. A barley seeding rate of 100 kg seed/ha did not impede forage production in the subsequent year.
