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.
