Trial details

Researcher(s) Andrew Ware (SARDI - Pt Lincoln)
Year(s) 2013
Contributor Lower Eyre Agricultural Development Association
Trial location(s) Cummins, SA
Ungarra, SA
Comparison of two seeding machines and interactions with herbicide treatments with effects upon weed numbers and subsequent grain yields locations
Aims

To compare two different seeder’s (Cross Slot and DBS) and compare:

  • Wheat emergence and establishment percentage (2 varieties – Scout and Wyalkatchem)
  • Herbicide effects on Annual ryegrass with each seeding system
  • Dry matter yields of crops under each seeding system
  • Grain yield
Key messages

Ungarra Site: No different in yields (grain or dry matter) between any of the treatments (ie seeder had no effect)

Cummins 2013

Sowing machinery

Seeders:

DBS – 5 tynes on 12 spacings with 4inch blades, airseeder delivery system

Cross-Slot – 5 seeding modules, constantly adjusting downwards pressure, on 13 inch spacings, combine gravity seed delivery system

 

Varieties:

Wyalkatchem & Scout
Sow date 17 June 2013 17/06/2013 and 18/06/2013
Harvest date Not specified
Plot size Not specified
Plot replication Not specified
Herbicide
  • Sakura @ 118gms/ha
  • Boxer Gold @ 2.5l/ha
  • Trifluralin @ 1/lha + Avadex Xtra @ 1.6l/ha
  • Sakura @ 118gms/ha + Trifluralin @ 1/lha + Avadex Xtra @ 1.6l/ha
  • Boxer Gold @ 2.5l/ha + Trifluralin @ 1/lha + Avadex Xtra @ 1.6l/ha
Other trial notes
  • The site was sown late.
  • During July/ August the site became quite waterlogged – large areas of ponding.
  • In Spring the gaps between the plots became infested with ryegrass – there were some interesting results from pre-em herbicides (see table 2).
  • Most of the trial had to be sprayed with glyphosate prior to harvest to stop ryegrass setting seed. A small, weed free area was kept to harvest.
