Optimising nutrition to maximise yield in canola in the HRZ

Understand the critical nutrients required to achieve high yielding (>3t/ha) canola crops, especially when wanting to chase yields with high N in-season.

Background

Project staff ran a series of workshops in high rainfall areas in WA in 2019 to understand key constraints and knowledge gaps when cropping within the HRZ (450-800mm annual rainfall) of WA. Among other things, optimising nutrition to maximise profitability was one such knowledge gap, especially considering fertiliser is the largest variable input cost. While there are a number of resources available that define critical levels of nutrition, this project is specifically focussed on growers with achieved or aspirational yields of 10t/ha in cereals and 5t/ha in canola, and so this trial will investigate whether the critical (or limiting) nutrients change at these high yields (and high levels of applied N).

Understanding the Importance of N, P, K & S Interactions in Wheat Cropping Systems

To investigate how nutrient interactions influence yield response. Specifically, if:

  1. Applications of P, K and/or S fertilisers influence wheat yield under varying N concentrations.
  2. “Background” nutrition influences fertiliser responsiveness.
  3. Yield responses are a result of absolute nutrient concentrations or ratios between essential nutrients.
