The GRDC Hyper Yielding Crops (HYC) project aims to push the boundaries of crop productivity and profitability in high-yielding regions across southern Australia. The 2022 dataset captures raw trial data from five states—Western Australia, South Australia, Victoria, New South Wales, and Tasmania—covering wheat, barley, and canola, depending on the location. Data are organised by site, crop type, and trial ID, and are presented in Excel spreadsheets containing original measurements and derived calculations (e.g., plant density), with each sheet including a key to units, codes, and abbreviations. The dataset is accompanied by a PDF report detailing experimental design, treatments, and environmental conditions such as soil and climate. Trial assessments were conducted using GDM ARM software, and metadata such as crop growth stage, assessment descriptions, and notes are provided within the spreadsheets. This research was made possible through the support of GRDC and contributions from growers and research partners, including FAR Australia, CSIRO, DPIRD, SFS, CeRDI, and several regional farming groups.
