Trial location(s) Inverleigh, VIC
Barley row spacing and agronomy trial (nitrogen trial) locations
Aims
  • To determine how nitrogen timings developed for canopy management (based on stem elongation timings) 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 nitrogen timing differs between lower and higher rainfall scenarios.
