Project Code: 3.1.1

Final Report: March 2013

Summary: Canola emergence is often only in the range of 40-60% even though high quality seed is planted. The objective of this study conducted in small plots and field scale strip trials across western Canada in 2011 and 2012 was to determine the effect of various seed drill opener types and ground speeds on resulting canola emergence in the
Canadian prairies. The results show that across all opener types, an increase in seeding speed from 4 to 6 mph caused reduced canola emergence in 20% and 33% of the comparisons in 2011 and 2012, respectively. Field-scale farm trials also indicated a general trend of reduced canola plant stands with higher seeding speeds.
