Critical level for Zn deficiency of wheat grown on soils of the West Midlands locations
Aims

Calibration of plant test for diagnosing zinc deficiency in wheat grown on responsive soils under field condition 

Key messages

A range of field experiments were conducted to calibrate a plant test for diagnosing Zn deficiency in wheat under field conditions • The combined results of 5 experiments conducted over 3 seasons indicated a diagnostic critical level of 12 mg Zn/kg (DW basis) in YEBs (youngest fully emerged blades) of wheat at mid-tillering to boot stage.
