Critical level for zinc deficiency of field-grown wheat locations
Aims

To calibrate a plant test for diagnosing zinc deficiency in wheat under field conditions.

Key messages
  • Field experiments were conducted in SA to calibrate a plant test for diagnosing zinc deficiency in wheat under field conditions.
  • The combined results of 12 experiments conducted over five seasons indicated a diagnostic critical level of 18 mg Zn/kg (DW basis) in YEBs (youngest fully emerged blades) of wheat at mid-tillering.
