Phosphorus by nitrogen response in wheat locations
Aims

To investigate responses to phosphorus and nitrogen in wheat.

Key messages
  • Early observations of crop vigour (11th July) found that the 0P plots at all rates of nitrogen were significantly less vigorous than the plots that had phosphorus applied, with the plants in the highest rates of P applied showing the highest vigour.
  • This response to applied P was still evident at the later observations of crop vigour on 8th August. This demonstrates the need to apply fresh phosphorus to crops at seeding to ensure good plant shoot and root growth during the early stages of crop growth.
  • For further results please see the attaached trial report.
