Response of wheat to N and K rates with added Cu locations
Aims

This trial was designed to test whether wheat growing on soil with low K levels will benefit from K application enabling it to make full use of applied N during the crop growth cycle. High yield potential crops in the area have shown decreased rigidity in foliage and tillers, with low Cu status suspected. Uptake of Cu can be influenced by rapid growth and N uptake. Application of Cu before rapid plant expansion was also to be tested.

Key messages
  • Trial sowing at 11 June was later than optimal but plant growth was showing strong response to nitrogen (N) and some response to potassium (K) at 28 August.
  • By harvest, Mace wheat showed significant grain yield response to nitrogen application but potassium response had moderated.
  • No significant differences were seen from Cu application.
  • Late sowing decreased yield potential from the start. Harvest yields ranged from 2 to 3 t/ha, with maximum yield and $/ha return at 80 kg N/ha and 12.5 kg K/ha.
