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” includes 66 replicated field trials per year for 3 years. The trials cover 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 aim is 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). 
Research Summary

Trials established in 2020 include: 25 in Finely, 19 in Kerang, 1 in Noorong, 8 in Frances, 2 in Griffith and 4 in Tasmania. The cops being investigated include faba beans, canola, durum, chickpeas and barley. 

The Chickpea trials include:
  • Influence of irrigation system on chickpea performance (overhead and flood) 
  • Influence of different rhizobium inoculants on chickpea yield and profitability under overhead irrigation
  • Influence of chickpea stubble incorporation on yield and profitability of following durum wheat
  • Disease management strategies for chickpeas grown under irrigation
