The authors of this paper note in the conclusion: “All four trials highlighted the amount of chickpea grain and income that can be lost at the front of the header at harvest. The impact of air assist or even the simple approach of attaching brushes to the reel provided benefits of ~$50/ha. However some caution is needed as both 2018 and 2019 were low yielding seasons with yields varying between 0.4 and 1.0 t/ha. The benefits of simple header adaptations may be more substantial in lower yielding years or where crop biomass or planting configuration is likely to result in poor levels of ‘feeding in’ of harvested material.”.

The Impact of Harvest Management in Chickpeas – Desiccation and Front of Header Losses

The take home messages from this GRDC  funded research are below. Please access the full paper via the link below for methodology, references, acknowledgements and discussion.

  • Generally minor impact from desiccant treatments or application timing on yield or grain quality
  • Decisions on harvest management choice should be determined by cost, attitude to Ally® plant back restrictions, weed spectrum present at harvest and speed of desiccation required
  • Delayed harvest at low % grain moisture caused more damaged and split grain than desiccant treatment or timing
  • Ideally target desiccation at ~85-90% pod maturity and schedule harvest 7 days later to reduce grain quality issues
  • Large levels of pod and grain losses were measured at the front of the header in four commercial evaluations (~100-200 kg/ha)
  • Losses reduced by ~50-90 kg/ha when harvested with air assist or when brushes were attached to the reel
  • Impact from the harvest modifications would have improved returns by $34-67/ha
  • In the trials conducted in 2018 and 2019, this represented an additional 5-18% yield.
