Effect of copper and zinc on wheat on newly cleared  yellow gravelly earth of the central wheatbelt locations
Aims

To determine the rates of copper and zinc required for maximum grain yield of wheat grown on  yellow gravelly earth.

Key messages
  • Zn application gave varying results in grain yield
  • Cu increased with Zn or without Zn added to superphosphate.  
  • All Zn depressed yield when no  Cu had been applied.
  • Zn O at 3.3 kg/ha depressed grain yield with 5.5 or less kg/ha Cu sulfate
  • Combination of Cu sulfate (2.75 & 5.5 kg Cu sulfate) and nil  KgZnO  /ha Cu 5.5 and ZnO 1.6 kg/ha all gave for maximum yield.
  • Plain superphosphate yield same as  Aerophos +gypsum.
