To determine the optimal combinations of canola cultivar, seeding rate, and seed size on wild radish seed production and canola growth and yield.
This study demonstrates that increasing canola seeding rate and using large canola seed size are important factors in achieving the highest yields whilst reducing wild radish seed production when sown to both open pollinated or hybrid canola varieties (Bonito and Trophy respectively).
