EFFECT OF ENVIRONMENTAL AND MANAGEMENT FACTORS ON GROWTH AND SEED QUALITY OF SELECTED GENOTYPES OF CAMELINA SATIVA L. CRANTZ

Abstract

Key aspects of the basic agronomy Camelina sativa were evaluated under controlled environment conditions and at multiple field locations in 2011 and 2012. Camelina is a highly adaptable crop. It germinates well even under low water availability and has a great potential for yield compensation. The line CDI007 was the most promising genotype with the highest yield potential, the lowest glucosinolate content, and the highest tolerance to downy mildew. The optimum N rate for seed yield varied by year and location: 100 kg N/ha at Truro and Canning in 2011, 120-150 kg N/ha at Canning, Truro and New Glasgow, 160-200 kg N/ha at Fredericton in 2012. N was positively correlated with protein content, but negatively correlated with oil content. Application of sulphur increased protein content at all of the sites and yield at some of the sites. In general, camelina response to S was maximized when N was sufficient.
