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.

Fertiliser

6-11 rates of soil-applied Zn, the highest rate being 20 kg Zn/ha and the lowest (apart from nil controls) 0.1 kg Z/ha. Zinc was sprayed onto the soil surface as a solution of zinc sulphate and incorporated with a rotary-hoe.
