dc.description.abstractSoybean (Glycine max L. [Merr.]) has become a popular crop choice for producers in Manitoba. In 2012 and 2013, 6 paired field experiments were established across southern Manitoba, three experiments seeded with a row-spacing of 25 cm, and three seeded with a row-spacing of 75 cm. Increasing densities of volunteer canola were broadcasted to determine the action threshold in soybean as well as evaluate soybean growth and development parameters. Height and branching were determined to be important parameters. The action threshold in narrow row-spaced soybean was 3.0 plants m-2 while the wide row-spaced soybean action threshold was 2.7 plants m-2. Digital images were captured between V3 and V4 to determine if early-season volunteer canola and soybean ground cover can be related to yield loss in soybean. There were no apparent differences between row types for image analysis and the method shows promise relating early-season ground cover to soybean yield loss.en_US
