Aims

To disucssion observations on barley and manganese in seeds on the Eyre Peninsula.

Key messages
  • Initial barley growth was increased 40-50% and final yield by 10% when using seed with greater nutrients, even on soils not associated with manganese deficiency.
  • Crops can drop into manganese deficiency late in the season with symptoms being pale, floppy leaves.
  • Sufficient concentraiotns are Copper 2-3 ppm in grain and 5ppm in leaf, and for zinc 15ppm in grain and 23-25 ppm in leaf.
  • Zinc is so cheap thatbit is worthwhile treating than taking any risk, at Wudinna this year a headland area not receiving zinc died while the remainder of the crop which received zinc survived the water stress.
  • Trace element deficiencies seem to beexacerbated in dry years.
