Effect of copper and zinc on wheat on newly cleared yellow to brown soils in the presence or absence of ironstone gravel in top 15 cm of soils of the central wheatbelt locations
Aims

To determine the rates of copper and zinc required for maximum grain yield of wheat grown on  yellow to brown soils in the presence or absence of ironstone gravel in top 15 cm of soils: summary of 13 experiments .

Key messages
  • General location only as 13 experiments are summarised for 1967.
  • Trials over 1965-1967 ; covers a range of locations for the central wheatbelt area
  • Gravelly sites only slightly more affected by Cu deficiency than sandy sites.
  • Summary of 13 experiments with 4 Cu and 4 Zn levels
  • Cu increased grain yield in the absence or presence of Zn.
  • Cu application increased grain yield by 35 - 50%
  • Zn depressed grain yield at nil Cu more in the gravels than sands
  • Combination of Cu sulfate (8.25 kg Cu sulfate) and 1.6 or 3.3 KgZnO /ha  for maximum yield on gravel sites
  • Zn nil or ZnO0.8 kg/ha Cu Sul 2.75 or 5.5 kg/ha on sandy sites
  • General conclusion 5.5 kg Cu sulfate and 0.8 kg/ha ZnO adequatefor sandy and gravelly surfaced yellow earths of the central wheatbelt of WA.
