Canola Growers Survey

Principle investigators: Elwin Smith, Agriculture and Agri-Food Canada, Lethbridge, AB

Collaborators: Richard Carew, Danny LeRoy, Scott Jeffrey

Surveys of Prairie canola producers during the winter of 2011-12 uncovered key factors that provide a positive contribution to canola yield. These were: nitrogen, irrigation, calibrating the seeder, swathing when seed colour changed, soil testing for fertilizer requirements, good to excellent moisture, and good to excellent temperatures during flowering. Factors that commonly reduced canola yield were: seeding late, adverse growing conditions and salinity.

During the winter of 2011-12, Agriculture and Agri-Food Canada (AAFC) and the Canola Council of Canada (CCC) sponsored a survey of canola producers to determine the management practices and inputs they commonly use. An independent survey company contacted producers, collected the required survey data from the set of questions, and provided a summary tabulation of the results.
