Abstract

Winter canola shows promise as an addition to crop rotations in Iowa. This project determined optimal seeding dates for this cover crop and explored practices to enhance production. It was estimated that the latest Iowa seeding date varies from around August 31 in the north to September 12 in the southeast.

Key Question

In Iowa, what is the optimal seeding date for winter canola in order for the plant to survive the winter?

Findings

As a general rule, in Iowa winter canola should be planted no later than early September in order to achieve maximum agronomic performance and provide the greatest environmental benefits, either as a cover crop or a cash crop.
