The impact of underseeding forage mixtures on barley grain production in northern North America
Livestock farmers in Newfoundland grow most of their required forage, yet must import most feed grain. Growing barley (Hordeum vulgare L.) in the year of forage establishment may allow for the incorporation of grain production into local cropping schemes. We examined the effect of barley grain produ...

Livestock farmers in Newfoundland grow most of their required forage, yet must import most feed grain. Growing barley (Hordeum vulgare L.) in the year of forage establishment may allow for the incorporation of grain production into local cropping schemes.
