Aims
  • To test further the PGR treatments that had the greatest effect on agronomic traits, to better understand the best application timings in order to improve performance and maximize yield potential of faba beans/broad bean.
Key messages
  • Contrasting results were obtained from the application of PGRs at the three different sites indicating environmental conditions may be an important factor for effective PGR response. In high rainfall environments such as at Conmurra in South East, there was no response to PGR application while variable responses for plant architecture (plant height and biomass) and grain yield were obtained in the medium rainfall environments such as Hart (Mid-North) and Cockaleechie (Eyre Peninsula) depending on PGR and treatment. The above average rainfall may have favoured high biomass production in high rainfall environments therefore overriding any effects from application of PGRs as was observed at Conmurra, South East, SA.
  • In medium rainfall environments such as Hart (Mid-North) and Cockaleechie (Eyre Peninsula) in SA, plant growth responses (plant height and biomass production) to PGR application were observed in some treatments. However where plant growth was reduced, a corresponding reduction in grain yield was also observed in comparison to the Nil treatment indicating that, in favourable seasons, a reduction in yield potential (biomass) may in-turn result in yields not being optimised.
  • A reduction in grain yield was observed at Yeelanna in 2016, following application of Ethephon at early vegetative growth stage. This result has not been previously observed in our trials and the cause for such a reduction is still unclear.
  • Further field evaluation across multiple application timings will occur to better understand the application timings that have the greatest effect on plant growth without a negative grain yield response.
