Optimising grain yield of thirty-two wheat varieties across sowing dates locations
Aims

To evaluate the response to sowing time of 32 current and new wheat varieties within the central west region of NSW. 

Key messages
  • Scepter (6.17t/ha) yielded the highest from the 20 April sowing date; Cutlass (4.38t/ha) yielded the highest from the 19 May sowing date; and Viking (3.22t/ha) yielded the highest from 1 June sowing date. 
  • The 20 April sowing date germinated and established well before the waterlogged conditions occurred during late May and early June causing reduced germination and poorer establishment for the 19 may and 1 June sowing dates (SD).  This low establishment resulted in reduced yields between sowing dates of 0.78t/ha from SD1 and SD2 and 1.01t/ha from SD2 and SD3.
  • Grain yields of varieties were highest when they were sown in their recommended sowing window.

Sow date Multiple - please see report
Harvest date Multiple- Please see report
Plot size Not specified
Plot replication Not specified
Psuedoreplication Not specified
Fertiliser

70kg/ha mono-ammonium phosphate (MAP) + Jubilee (Flutriafol 500g/L) at 400mL/ha (fungicide on fertiliser).

Herbicide

Once established, the experiment was well maintained and weed-free.
Grass weeds were controlled with in-crop herbicide application of Axial® at 300 mL/ha + Adigor® at 500 mL/100 L of water. An application of Precept® at 1 L/ha + Hasten™ at 500 mL/100 L water for broadleaf control. Broadleaf weeds were further controlled with a late season application of L.V.E. Agritone® at 500 mL/ha + Ally® at 5 g/ha.
