Year(s) 1963, 1967 - 1969
Contributor The University of Adelaide
Trial location(s) Warooka, SA
The correction of manganese deficiency in barley crops locations
Aims

To establish the most satisfactory method to correct manganese deficiency in barley on calcareous sands

Key messages
  • 67% of divalent manganese incubated on calcareous sands form Warooka was immobilised within 167 hours by chemical and biological processes.
  • In field experiments over seven years manganese up to 16 kg/ha drilled with the barley crop did not prevent manganese deficiency in crops.
  • However, manganese applicaiotn increased crop growth, delayed deficiency symptoms and increased grian yield by an average of 61%.
  • The optimum applicaiotn at seeding was 6 kg/ha manganese (25 kg/ha nanganese sulphate).
  • Three foliar sprays of manganese did not completely correct manganese deficiency.
  •  The best results were obtained by applying 6 kg manganese at sowing followed by three foliar sprays.
