Enhanced phosphorus fertiliser efficiency in wheat locations
Aims

To assess the ability of some of the above techniques to significantly improve phosphorus fertiliser response.

Key messages
  • The trial showed up to a five-fold increase in dry matter at DC41 when 20 kg/ha of phosphorus was applied. This translated into a doubling of yield, despite waterlogging and stripe rust at the site.
  • A low rate of P (5 kg/ha) did not provide a statistically significant yield response while higher rates (10 and 20 kg/ha) did.
  • Soils continue to be highly responsirve to phosphorus even at higher Colwell P levels.
  • There is some evidence of adequate phosphorus nutrition improving grain quality (screenings) through earlier maturity.
