Effect of time of sowing and variety on grain yield: MAC demonstration locations
Aims

To compare grain yield and grain quality of a mid-late maturing variety (Trojan) and two early-mid season maturing varieties (Mace and Scepter).

Key messages
  • There was no difference in grain yield (t/ha) between the early season variety (Trojan) and the later varieties (Mace and Scepter) sown 13 days later.
  • In 2016 sowing Mace and Scepter earlier on 13 May reduced grain protein by 0.3% compared to sowing it thirteen days later.
  • For the later sowing on 26 May, Mace and Scepter had similar grain yield, however, protein was higher for Scepter.
  • When sown early, Trojan had higher protein than Mace and Scepter.

Sow rate or Target density 70 kg/ha
Sowing machinery

On 13 May Trojan was sown using a 30 ft (9 m) air seeder along the full length of the paddock using three repetitions at 70 kg/ha seeding rate with 60 kg/ha DAP (18:20:0:0). Mace and Scepter were also sown at 70 kg/ha seeding rate with 60 kg/ha DAP (18:20:0:0) on this date for comparison between these two varieties.

 

The late time of sowing was on 26 May with Mace and Scepter, using the same rates of seed and fertilizer as the Trojan. These varieties were sown on strips left between the early sowing, so no extra chemicals were used. As Trojan is a longer growing season wheat variety, it was not included in the later time of sowing.

 

The paddock strips were harvested using a plot header with four 8.6 m strips per variety with three repetitions done across the demonstration area. Only averages can be compared between varieties with different times of sowing

Herbicide

Knockdown chemicals used were 1.5 L/ha of glyphosate, 500 ml/ha ester 680 and 118 g/ha Sakura + SOA and Li 700. Sakura was used to help control grass weeds as there was little germination of weeds at sowing.
