Canola Yield Decline Analysis

Researcher:

Mr. Stuart Brandt, Agriculture and Agri-Food Canada, Scott, SK, Dr. R. Berard, AAFC, Saskatoon, SK

Project Code:

CARP 9818

Final Report:

January 2000

Summary:

An analysis of yield trends in Saskatchewan for various major crops have shown that although yields of barley and flax have been continuously increasing from the 1960's through to 1999, canola yields have remained stagnant between 1991 and 1999. To try to determine why, researchers looked at historical trends as well as agronomic factors across Saskatchewan. Although the study did not find conclusive evidence for the yield decline, the results show evidence that a canola yield problem did exist in Saskatchewan.
