To compare the effects of variable urea rate on two soil types.
To compare different rates of urea applied at GS30.
Additional N did not have an economic advantage in this season.
Paddock and demonstration site suffered from the dry 6 weeks period mid season.
Stem rust devastated potential 3 ton crop reducing yield by 50%. This combination resulted in poor yields, low test weight and high screenings.
Good soil showed improved protein over deeper sand regardless of extra N applied.
Extra N marginally improved protein but not enough economically to apply more.

TerminologyOnline Farm Trials: a web-based information system that provides open and free access to agricultural-based research trial data and information. OFT is a digital online resource managed through a collaboration between the Grains Research and Development Corporation (GRDC) and the Centre for eResearch and Digital Innovation (CeRDI) at Federation University Australia (FedUni).
Trial Contributor: an individual or organisation (e.g. grower group, research centre, commercial entity or government department) that makes data and/or other information available through OFT.
Metadata: information about Trial Projects submitted to OFT (e.g. names of the Trial Contributors, Trial Project title, Trial site location, Crop type(s), Growing season year(s), Trial type and Trial design). This data is compiled by OFT from information submitted with Trial Projects.
