Project Code: 3.1.3

Final Report: April 2013

Summary: Management of stubble height is an inexpensive crop management technique that can have a potentially beneficial impact on seedling germination and emergence. Researchers conducted trials at seven locations on the Canadian Prairies during 2011 and 2012 to investigate the potential influence of preceding spring wheat standingstubble height on the emergence and performance of subsequently seeded canola crops. The results showed no consistent significant effects of standing stubble height on canola emergence or disease pressure at any of the seven sites, although there were significant differences between sites and years, which may be mainly attributed to variation in weather conditions.
