Early sowing options: wheat phenology and yield responses – Wallendbeen 2019 locations
Aims

Recently, breeders have released a number of new winter wheat genotypes suited to early sowing. In 2019, field experiments were conducted at two sites: Wallendbeen (southern NSW) and Wongarbon (central NSW) to determine the influence of phenology on grain yield responses for a set of 16 commercial and newly released genotypes in response to sowing date (SD).

Key messages

• Despite the significant effect of seasonal conditions in 2019, grain yields of >5.5 t/ha were achieved, highlighting the opportunity for early sown winter wheats in grain-only systems. • Differences in phenology and yield responses across sowing dates suggest cultivar
performance can be manipulated by sowing time and can vary across environments. • New winter and long season spring types with consistent yield performance provide alternative early sowing options for growers in southern NSW.
