Abstract

Field experiments were conducted under no-tillage at three locations in Alberta, Canada over 3 yr to quantify the relationship between barley seeding rate and plant density in a hulled (AC Harper) and hull-less (Peregrine) variety seeded at two depths (2.5 and 6.25 cm). Regression analysis indicated that barley emergence was consistently better with the hulled variety and at the shallower depth. Predictive equations can help determine appropriate hulled and hull-less barley seeding rates required to obtain desired plant densities.
