Full stubble retention: effect on crop growth and growing conditions locations

To investigate the effect of full stubble retention compared with other stubble management methods and seeding technologies.

Key messages
  • There were no significant differences in lentil grain yield among seeding system or stubble treatments.
  • Stripper and conventional stubble treatments resulted in taller and more erect plants with higher pods, improving harvestability
