Effect of sowing date on yield and quality of twenty barley varieties locations
Aims

To examine the effect of sowing date on yield and quality of twenty barley varieties.

Key messages
  • Slower maturing varieties had the highest yields in 2016, uncharacteristic of long-term yield trends in central west NSW, where weather conditions typically favour shorter-season varieties.
  • While anthesis date is a important contributor to yield, high rainfall and a long grain filling period diluted this association and was confounded by lodging, secondary tillering and waterlogging events.
  • Highest yields were attained from the second sowing date (mid May), while late sowing dates suffered yield penalties due to poor plant establishment from waterlogging.

Treatment type(s)
  • Crop: Variety
  • Sowing: Timing
Trial type Experimental
Trial design Randomised,Replicated,Blocked

Condobolin 2016

Sow rate or Target density 120 plants per square metre
Sowing machinery

Sown using a six-row DBS plot seeder at 30 cm row spacings with 120 plants/m2 the target plant density

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

Fertiliser applications were applied as per regional farming practices.
At sowing, 70 kg/ha mono-ammonium phosphate (MAP) was applied, providing an additional 7 kg/ha of available nitrogen (N).
On 17 August, 30 kg N/ha was applied as urea on sowing dates two and three in response to heavy rainfall leaching N from the soil.

Herbicide

Pre-emergent weed control: glyphosate (450 g/L) 2.0 L/ha
In crop application: L.V.E. Agritone® 600 mL/ha, Ally® 5 g/ha
