Long-term cropping systems trial locations
Aims

To compare the performance of three seeding systems and two nitrogen nutrition strategies.

Key messages
  • Wheat grain yield was not significantly different between seeding systems or level of nitrogen, averaging 5 t/ha.
  • The high nutrition treatment increased grain protein.
  • The high nutrition treatments had accumulated 28 kg N/ha more soil available nitrogen compared to the medium treatments to a depth of 60 cm.
