Use of crop sensors for determining nitrogen application during stem elongation in wheat locations
Aims

To determine whether crop reflectance at particular wavelengths of light can be used during stem elongation to determine N content of the plant and the need for applied N.

Key messages
  • The optimum nitrogen rate, regardless of timing, to maximise yield was 75kg N/ha, though protein contnet was maximised at higher N rates.
  • Further investigation is required to define correlations between crop reflectance (NDVI) and N uptake.
