Yield and water use improvements of South Australian wheat varieties from 1957-2007 locations
Aims

To monitor water use with a capacitance probe installed in each plot to update the water use efficiency benchmark of 20 kg/ha/mm derived from French and Schultz.

Key messages
  • An increase of wheat grain yields released between 1957 and 2007 was found.
  • Yields have increased because of improved harvest index, more biomass at flowering, and increased grain number.
  • Nitrogen is critical in allowing each variety to reach its potential through increasing growth rate between stem elongation (GS31) and flowering.
  • WUE has improved over the 1957-2007 timescale through increased yields, not greater extraction of water.
