Rankins Springs row spacing x seeding rate x sowing date trial locations

To compare yield at three row spacing’s (25, 50 and 75cm) and two seeding rates (20 and 40 kg/ha) when
sown early and late.

Key messages
  • Row spacing and seeding rate made no difference to yield when sown on 4 May.
  • When sown 24 May, yield decreased with wider row spacing’s, and slightly increased with higher seeding rates.
  • The variation in this trial was large due to previous seasons header rows.
