Nutrient Requirement of Camelina (Camelina sativa L.) As Bioenergy Feedstock.

Camelina [Camelina sativa (L.) Crantz., Brassicaceae] is an oil seed crop. It is a potential crop as feedstock to produce biodiesel for jet fuel in the USA. We evaluated the effect of nitrogen (N), phosphorus (P), potassium (K) and sulfur (S) on camelina seed yield, oil content and oil composition at Central and North West Montana. The experiment was carried out in a randomized complete block design with four replications using spring camelina variety, Suneson. The treatments include four levels of N (0, 45, 90 and 134 kg N ha^-1), two levels of P (0 and 22 kg P₂O₅ ha^-1), two levels of K (0 and 22 kg K₂O ha^-1) and three levels of S (0, 11 and 28 kg S ha^-1) and all fertilizer were applied three weeks after camelina germinated. The three years and two locations data will be analyzed using GLM of SAS and orthogonal contrast to determine the agronomic benefits of these nutrients in increasing yield and improving oil content and composition.
