Study Name: Spring-seeded Roundup Ready canola under conventional tillage system

Study Number: 9940C

Objectives: Compare spring-seeded canola in conventional tillage to no-till (see 9940N)

Results: Weed control was better with Roundup applied in a split application at 1pt/1pt or 0.5pt/0.5pt compared to a single 1 pt application. Roundup was slightly weaker on wild buckwheat and common mallow even with the split applications. Surprisingly, canola yield was better in the plot that received only the single application.
