Wheat  row spacing trial locations
Aims

To assess different interrow spacing widths using five different sowing treatments.

Key messages

Although only a demonstration, the various treatments within the later sown trial showed that small yield differences between the various row spacing treatments. With the earlier sown trial, narrow row spacing gave higher yields, however there were some deficiencies with the trial design which means that a confident conclusion can’t be reached.
