• Winter canola is a common oilseed crop grown in regions outside the Midwest. Due to its ability to overwinter, it may be a suitable candidate for use as a cover crop in Iowa crop production systems.
• Winter canola was seeded at three dates in the late summer and early fall to assess growth, ground cover and nitrogen accumulation by the above ground biomass in two fall–spring cycles: 2012–2013 and 2013–2014.

KEY FINDINGS
• Winter canola seeded in early September produced the most growth and ground cover and accumulated the most N in the aboveground biomass in the fall.
• Winter canola successfully overwintered when seeded in early September and mid-September in the 2012-2013 Cycle only.
• Winter canola performance as a cover crop tended to decrease as seeding
