Yield response of 32 bread wheat entries across three sowing dates – Trangie 2016 locations
Aims

Sowing date is a key driver of yield and variety performance. The optimum sowing time for an individual variety is a balance between having the variety flower too early and being subjected to frost damage, and conversely having it flower too late and experience prolonged heat stress. Both of these factors can have significant negative impacts on yield.

Key messages
  • The quicker maturing varieties LRPB DartA, HatchetA LivingstonA, MaceA, SceptreA, MitchA and SuntopA were generally lower yielding than other entries at SD1, but were more yield competitive with other entries at SD2 and SD3.
  • The longer season varieties EGA WedgetailA (6.08 t/ha) and EGA EaglehawkA (5.88 t/ha) were the highest yielding varieties at SD1, followed by CutlassA (5.51 t/ha) and LRPB FlankerA (5.36 t/ha).
  • The mean yield at SD1 (4.89 t/ha) was not significantly different from SD2 (4.63 t/ha), but SD3 (3.56 t/ha) was significantly lower yielding than either SD1 or SD2.
  • All varieties yielded their lowest from SD3.
  • Protein percentages were low to moderate (mean of 9.8% for SD2 and 10.3% for SD1) with no significant difference from SD for any of the entries

Other trial notes

This experiment highlights the potential value of earlier sowing dates in this environment. Averaged across entries, there was a 27% yield decline when sowing was delayed until the end of May (SD3) compared with planting at the end of April (SD1). There was still an average yield decline of 23% when sowing was delayed from mid May (SD2) to the end of May (SD3).

Although the average yield of entries was not significantly different between SD1 and SD2 there were still some large differences for individual entries. EGA WedgetailA (by 1.45 t/ha), EGA EagkehawkA (by 0.95 t/ha), UQ01553 (by 0.72 t/ha), BeckomA (by 0.71 t/ha), CutlassA (by 0.68 t/ha), LRPB FlankerA (by 0.59 t/ha) and LPB12-0648 (by 0.55 t/ha) were all significantly higher yielding at SD1 than at SD2 (Table 1). These are all mid–long season entries, which further highlights the potential value of matching maturity type to planned sowing date to maximise yield potential.

However, results from this sowing date experiment at Trangie in 2016 should be used with caution, as the season was atypically mild, wet and cool during the grain-filling period with few frosts. These conditions produced abnormal yield responses in some longer season varieties such as EGA WedgetailA, but still highlights the extra yield potential (generally >1.0 t/ha) of these entries in favourable seasons.
