Aims

To determine optimum nitrogen nutrient management for hyper-yielding canola.

Key messages

 Canola responded to N input (as urea) but only to 75 kg/ha N, with no yield response with further urea N input.
 The application of pig manure at 6.7t/ha with 225kg/ha N increased yield compared to where 225kg/ha N (as urea) was applied alone.
 The project team will aim to better understand the response to manure, especially as the response was over and above a very high rate of applied N. Should phosphorus input recommendations be changed for very high yield potential environments or are there other
aspects of the manure driving the positive yield response?
 There was no effect of nutrient management on oil or protein concentration, but the manure application increased crop height by 8.7 cm.
