Crop competition in chickpea and faba bean against sowthistle – Wagga Wagga 2017 locations
Aims

 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.
 

Key messages

• 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.
 

Wagga Wagga ACT 2017 Faba beans

• 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.
