Early seeding - a climate change adaptation method in the North Eastern (NE) Agricultural Region of Western Australia (WA). locations
Aims

Compare the yield responses of wheat varieties sown at three sowing dates (9 April, 23 April and 12 May) and two plant densities.

Key messages
  • Forrest was the highest yielding variety for the 9 April sowing date (Table 6). Shorter season varieties were not able to capture the yield benefits of this time of sowing.  Plant densities of 60 and 120 plants/m2 did not influence the grain yield or quality of wheat when sown on the 9th and 23rd April.
  • Magenta was the highest ranked variety when sown on 23 April, however other long-mid maturing varieties also compared favourably.
  • Mace , the most widely grown variety in the state, maximised yield at the 12 May sowing time.  It out yielded all other varieties at this sowing date.
  • There was no influence of sowing time and plant density on the screenings which were below 5% for all varieties at all sowing times.
