The GRDC Project “Development and validation of soil amelioration and agronomic practices to realise the genetic potential of grain crops grown under a high yield potential, irrigated environment in the northern and southern regions” included 66 replicated field trials per year for 3 years. The trials covered the major irrigation types distributed across the Murrumbidgee and Murray Valleys of southern NSW, the Murray Valley of northern Victoria, south-east SA, SA/Vic Mallee and Tasmania.
Project Aim
The project aimed to evaluate crop response to agronomic practice across a range of irrigated systems and quantify yield potential in different environments (targeting >4 t/ha canola, >6 t/ha in faba bean, >10 t/ha in durum and >19 t/ha in maize). 
The Barley trials include:
  • Nitrogen Use Efficiency Trial – N rates 
  • Nitrogen Use Efficiency Trial – N Timing trial 
  • Germplasm disease management interaction
  • Disease management for irrigated crops – products, rates and timings 
  • Lodging control in irrigated crops – winter and spring barley
