Wheat phenology and yield responses to sowing time – Marrar 2019 locations
Aims

In 2019, field experiments were conducted across 10 sites in the northern grains region (NGR) to determine the influence of phenology on grain yield responses for a diverse set of wheat genotypes.

Key messages

• Phenology and grain yield responses were significantly influenced by seasonal conditions in 2019.
• Severe heat stress and terminal drought conditions favoured faster developing spring genotypes, which achieved the highest grain yields in 2019.
• Grain yield responses varied in response to sowing date, and highest yields occurred when phenology was matched with recommended sowing windows.
