Copper deficiency. Probable cause of the purpling symptom in irrigated winter wheat



Copper deficiency. Probable cause of the purpling symptom in irrigated winter wheat



Zimbabwe Agricultural Journal 78(5): 185-186



Symptoms of purpling or bronzing of stems and heads were observed on irrigated winter crops grown on sandy soils. Soil samples taken from affected patches at 4 sites contained extremely low EDTA-extractable Cu concs. while adjacent healthy patches contained more Cu. Soil Zn and P contents were high on 3 of 4 soils sampled. Leaf and grain material from 8 affected areas contained less Cu than adjacent healthy areas.
