Defining guidelines for canopy management in barley for the different climatic regions of Australia locations
Aims
  • To determine whether nitrogen timing and dose interacts with plant populations in terms of yield, crop structure and predisposition to lodging.
  • To determine the influence of N application at stem elongation versus up front N in terms of crop structure, yield components and quality parameters.
  • To examine how nitrogen timing and rate influences green area and green leaf retention during grain fill (not reported in this summary).
Key messages

June 13th sown Gairdner produced yields in the range of 4.86 – 5.69 t/ha following canola stubble. With high soil nitrogen reserves (203 kg/ha N, 0‐90cm) recorded at sowing, there was a small but significant response to applied nitrogen (0.21 t/ha at 50 kg/ha N & 0.23 t/ha at 100 kg/ha N). There was a significant advantage to nitrogen timed during stem elongation (GS31‐33) over nitrogen applied in the seedbed.
