  • Application timing
    – Application at 5% flowering recommended as it consistently increases yield
    – Application at 10 nodes/mid July largely failed to increase yield
  • Rate
    – 30L/ha is the recommended rate as over the 7 years of trial data it consistently increased yield
    – 45L/ha is not recommended as it generally did not increase yield above what was achieved with 30L/ha
    – 20L/ha is not recommended as it did not consistently increase yield
  • Yield impact
    – Yields increased by 0.2 - 0.4 t/ha
  • Economics
    – Across 7 years of trials $140/ha Net Return with Chickpeas @ $600/t OR $5 return for every $1 spent
  • Take home message – 30L/ha rate applied at 5% flowering is the best bet to increase yield and achieve a good
    return on investment
