Maintaining profitable farming systems with retained stubbles in the Upper North of SA locations
Aims

The demonstrate issues key to the current GRDC funded Stubble Initiative Project.

Key messages
  • The Seeder Demonstration enabled a large number of farmers to see and compare a wide range of seeding equipment in the one paddock on the same day.
  • Machine depth and accuracy of seed placement affected plant establishment.
  • A germination test is a simple process and can result in significantly better plant establishment.
  • An incorrectly calibrated or set-up precision seeder will result in poor germination rates and potentially reduced yield.
  • A well calibrated and set-up conventional seeder or knife point and press wheel seeder will result in good plant establishment rates and good yields.
  • Cultivation had a negative effect on plant establishment.
  • Prickle Chaining had a negative effect on plant establishment.
  • Precision Seeders showed better plant establishment due to better seed placement, however this did not uniformly translate into a yield benefit.
