Trial location(s) Site 7, Inverleigh, VIC
Barley row spacing and agronomy trial (phosphorus trial) locations
  • To determine how phosphorus rates can be used to optimize canopy management, apply to wider row spacing (300mm compared to 200mm) for both dry matter production, yield and grain quality outcomes.
  • To establish whether the interaction between row spacing and phosphorus rate differs between lower and higher rainfall scenarios.
