What effect does time of sowing and nitrogen have on wheat yield? locations
Aims

To investigate the use of different sowing timings and N management to improve yield and maintain protein of wheat.

Key messages
  • Sowing date combined with appropriate variety selection and adequate nitrogen supply was key to increasing grain yields.
  • Nitrogen fertiliser decision needs to consider the maximum attainable yield and be adjusted for the seasonal conditions and initial available soil nitrogen.
