Effect of sowing date on phenology and yield of eight canola varieties – Leeton 2017

Abstract

Key findings • • The winter canola varieties SF Edimax CL and Hyola® 970CL achieved consistently high yields for all three sowing dates (late March to early May). • • All spring varieties (except Victory® V7001 CL) were penalised by early sowing due to frost damage, with yields increasing as sowing time was delayed. • • The yield of the slowest-developing spring variety, Victory® V7001 CL, was stable but relatively low across sowing dates. • • Early sowing fast-developing spring varieties exposes them to a greater risk of frost damage.
