Aims

The trial had two similar but related objectives.

  • To evaluate the influence of macro and micronutrient rates and timings on dry matter production, grain yield and harvest index in grain maize.
  • To evaluate the fluctuations in macro and micronutrient tissue levels that occur both naturally in grain maize and in response to alternative strategies for nutrition.
Key messages
  • With an average grain yield of 16.51t/ha there were no significant differences in header grain yield from varying nitrogen rate or applying liquid potassium products.
  • Applying Calcium Nitrate Ca (NO3)2 caused a decrease in yield when it was combined with an additional application of pre drill 90 kg/ha of nitrogen.
  • There was evidence that additional nutrients significantly interacted (p=0.044) with the overall level of N fertiliser applied with liquid calcium nitrate giving greater benefits with 230N (applied as fertigation than when N was application was increased to 320kg N/ha (predrill urea = fertigation).
