The interaction between seeding rate and seed size of hybrid and open pollinated canola (Brassica napus) varieties on wild radish (Raphanus raphanistrum) growth and competition. locations
Aims

To determine the optimal combinations of canola cultivar, seeding rate, and seed size on wild radish seed production and canola growth and yield.

Key messages
  • 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).
