This podcast presents insights adopted from an article published in the Irrigation Research Extension Committee’s Farmers’ Newsletter, 209, Autumn 2023, titled: Growth Regulator Performance Dampened in Season 2022 by Sam O’Rafferty and Hayden Petty from Summit Ag Agricultural Consulting.

In 2022, two trials were conducted to investigate canopy and lodging management in irrigated barley at Whitton and irrigated durum wheat at Darlington Point as part of the Optimising Irrigated Grains project, funded by the Grain Research and Development Corporation.

Focus paddocks provided an opportunity to run these trials to investigate crop production issues raised by local growers.

The trials looked at the influence of fertiliser, variety and plant growth regulators, or PGRs, on cereal crops and the influence these had on yield and standability.
