Abstract
Camelina is a new oilseed crop to western Canada with potential applications in cosmetics, human nutrition, and biofuel. Nitrogen recommendations for camelina production in Western Canada aren’t available. Field studies were conducted in 2008 and 2009 for 10 site years at locations in western Canada to determine the effect of nitrogen rate on seed yield. Depending on the experiment, nitrogen rates ranged from 0 to 200 kg ha-1. The join point (N rate at which yields plateau) for camelina were 111 to 116 kg ha-1, which is similar to other Brassica oilseed species.
