Tolerance of some winter and summer crops to copper deficiency locations
Aims

To screen winter and for summer crops for the tolerance of copper deficiency in glasshouse trials.

Key messages
  • Wheat, barley, triticale, canary seed, sorghum, sunflowers, millet and panicum were grown in a copper deficient clay soil in pots in the glasshouse.
  • For rates of copper from 0 to 6 mg per pot for winter crops, and the same plus 60 mg per pot applied to the summer crops.
  • A rate of 6 mg per pot was not sufficient to maximise yield from the winter crops but some are crops produced maximum yields when 60 mg per pot was applied.
  • Significant differences intolerance to copper deficiency were apparent between varieties within crops.
  • Only the summer crops in triticale produce grain when nearly all the lowest rates of copper were applied.
