Aims

To improve understanding of the performance and profitability of different crops and short-season varieties when sown in June.

Key messages

Vixen wheat provided the highest total return in this trial.
Late June-sown canola yielded significantly less than mid-June sown canola.
No differences in yield for cereal and legume crops between the two sowing times.
Grain quality parameters showed only small differences between sowing times, with overall grain quality broadly similar at harvest.
