Effect of sowing date on flowering and grain yield of ten canola varieties in a high yielding environment – Wallendbeen 2019

Abstract

Key findings • In 2019, the highest yields came from sowing in late March due to the dry spring conditions and only mild frosts at Wallendbeen. • Nuseed Diamond was the highest yielding variety from all sowing dates. The highest yield was from the late March sowing date. • The winter varieties were lower yielding than the spring types, with yields declining from later sowing dates. • Open pollinated triazine tolerant varieties were generally lower yielding than the hybrid Clearfield® varieties with similar phenology.
