Camelina: Grain Yield and Protein Response to Applied Nitrogen In Oregon, Washington, and Idaho.

Nitrogen rate trials were conducted on camelina (cv. Calena) at four locations in the Pacific Northwest Lind, WA (LD), Pendleton, OR (PN), Moscow, ID (MW), and Corvallis, OR (CS), during the 2008, 2009 and 2010 crop seasons. These locations represent four distinct environments in the PNW.  Respectively, annual crop-year precipitation at these sites averaged 228, 421, 760 and 993 mm.  Beginning at zero; six rates of N were applied at each location.  Incremental rate differences were 10kg/ha at LD, 15kg/ha at PN and 20kg/ha at MW and CS. Optimum rates varied among years and locations because of the amount and distribution of precipitation, residual N level, and temperature. ANOVA of showed that year and rate were significant (P=0.01) at each location. In general, camelina appears to require 5-6 kg/ha N/100 kg of grain yield.  Yields at LD, PD and MW show camelina can be a viable crop. Yields at CS show camelina to be economically unfeasible compared to higher yielding crops.
