Camelina is a summer annual oilseed crop. Camelina has many uses, including potential as a single use cooking oil, salad oil, biodiesel, health food supplement, and bio-lubricant. Camelina is high in omega-3 oil, important in human health and nutrition. This project will evaluate crop response to varieties, seeding rates, nitrogen rates, planting dates, and following wheat crop response to camelina. Experiments proposed in this project will be done over multiple growing seasons. The goal of this proposal is to develop agronomic practices and foster adoption of camelina as an alternative crop in Pacific Northwest crop production systems. Camelina will be investigated by : 1. camelina planting practices for successful stand establishment, 2. cultivar testing and screening, 3. nitrogen and sulfur fertility, 4. following wheat crop response to camelina, Obj. 1 Camelina Planting Camelina is much more cold tolerant than canola and has shown very promising results in preliminary testing in the region (Ehrensing and Guy, 2008). Camelina could be planted in either late fall or early spring because of the cold tolerance. Six planting timings will be investigated from dates normally used for winter wheat, through the winter and early spring, and ending with spring crop planting dates. Successful planting is a key to developing optimum methods to grow this crop. Broadcast seeding of camelina will be evaluated. Obj. 2 Cultivar Evaluation Available germplasm must be evaluated to identify the most adapted germplasm for various cropping systems. Emergence under cold conditions, vigorous seedling emergence, and early plant maturity are traits that are important in these production systems. As many as 15 to 30 genotypes could be tested. Obj. 3 Nitrogen and Sulfur Fertility Previous work suggests that nitrogen requirement for camelina is lower than canola or wheat. Nitrogen is a major off-farm input. Camelina will be grown in replicated trials nitrogen rates with and without sulfur to assess the contribution to oil content and yield. Objective 4. Following Wheat Response The previous crop to winter wheat can have significant influence on the performance and response to N fertilization. Usual crops grown previous to winter wheat include : spring wheat, barley, dry pea, lentil, mustard, and canola. These crops and camelina will be grown in year one prior to the second year winter wheat. The winter wheat will be managed with variable nitrogen fertilizer rates to assess N fertilizer response. Education, Outreach, and Scientific Contribution Outputs Integrating production of camelina into existing production, marketing, and infrastructural systems is important to building an oil seed industry. Information and results from these investigations about camelina production practices, genotype traits, fertility management, response in rotation with wheat, and end use characteristics will be provided to grower groups, regional cooperatives, and industry representatives. Preliminary economic analysis of camelina production has been conducted and results from these studies with help refine the cost of production analysis.
