Effect of sowing date on the phenology and grain yield of sixteen barley varieties – Condobolin 2017 locations
Aims

To assess the performance of 16 commercially available barley varieties sown on three dates at the Condobolin Agricultural Research and Advisory Station in 2017

Key messages

• Frost and terminal drought were key determining factors on barley grain yield and development at Condobolin in 2017.
• Selecting sowing date and varietal phenology maximised grain yield by timing flowering for the first week of September at Condobolin.
• Grain plumpness, as indicated by screenings and retention, can be adversely affected by late sowing dates in the absence of spring rainfall.

Condobolin NSW 2017

While early faster maturity varieties such as HindmarshA and La TrobeA and early sowing dates have predominated in the past several years, 2017 illustrated the risk of early flowering dates exposing the crops to frost damage during critical periods. By targeting a flowering period of early September, crops were provided with the best opportunity to avoid frost while ensuring sufficient time for grain fill in the event of moisture stress in spring.
