Camelina is a relatively new oilseed crop to western Canada. Currently there is little research available for camelina seeding rates in western Canada. A field study was conducted in 2007 and 2008 for 9 site years at locations in western Canada to determine the effect of seeding rate on various agronomic aspects of camelina like yield, days to maturity, lodging, and plant height. The seeding rates used were 12, 25, 50, 100, 200, 400, 800, and 1600 seeds m-2. Camelina exhibited a plastic yield response to seeding rate. Maximum yield was reached at 450-500 seeds m-2. Small yield increases were seen with seeding rates greater than 100 seeds m-2. Days to maturity decreased by up to seven days as seeding rate increased. The optimum seeding rate was approximately 500 seeds m-2 because of the positive effect on maturity, plant height, and yield. 500 seeds m-2 would supply enough seeds to produce an acceptable plant density under poor seeding conditions to help prevent crop failure due to poor emergence or seedling mortality.
