Wheat seeding rate demonstration in a low rainfall zone locations
Aims

To compare three different sowing rates (in a low rainfall zone) in a farmer sized trial and monitor these plots throughout the growing season.

Key messages
  • The average sowing rate in low rainfall zones is 50 kg/ha.
  • Increasing seeding rates is generally not helpful for yield as moisture is limiting in this zone.
  • Higher seeding rates can have other benefits such as reducing weed burdens.
