To investigate whether competitiveness can be increased in chickpea and faba bean to reduce sowthistle biomass and seed production, and how this affects crop yield.
• Decreasing row spacing and increasing plant density improved chickpea and faba bean competitive abilities.
• The improved competitive abilities improved yields and reduced sowthistle biomass and seed production, which will improve weed control in subsequent crops.
• Crop competition in chickpea and faba bean can be improved by increasing plant density and using narrow row spacing.
• In both faba bean and chickpea experiments, increasing crop populations resulted in fewer weed seeds/head. However, there were no differences in seed number/head between the wide- and narrow-row treatments in both experiments.
• Higher faba bean and chickpea populations resulted in lower sowthistle height, biomass, seed heads/plant, seeds/plant and seeds/m2. Narrow-row spacing in both crops also significantly reduced sowthistle biomass and seeds/m2.
