Abstract

A western Canada field study investigated the effects of seeding date and rate on malting barley quality. Seeding date had little effect on quality. Increasing the seeding rate up to 300 seeds m^-2 resulted in higher germination and Kolbach indices, lower β-glucan, and better endosperm modification without compromising malt extract.
