To present results from the large plot focus farm trials of the Maintaining profitable farming systems with retained stubble in the Riverine Plains region project, which where to

• investigate, demonstrate and extend cultural practices that will assist growers to adopt no-till stubble retention (NTSR) in medium and higher-rainfall environments;
• build on findings from the previous Riverine Plains Inc. Water Use Efficiency (WUE) project; and
• extend the frontier of agronomic knowledge for crops grown in NTSR systems.

The project seeks to:

• investigate, demonstrate and extend cultural practices that will assist growers to adopt no-till stubble retention (NTSR) in medium and higher-rainfall environments;
• build on findings from the previous Riverine Plains Inc. Water Use Efficiency (WUE) project; and
• extend the frontier of agronomic knowledge for crops grown in NTSR systems.

This project aims to determine if nitrogen supply is limiting uptake of sulphur in canola crops grown in the Riverine Plains region and whether sulphur uptake and yield is increased in canola when nitrogen is available in non-limiting quantities.
The 2017 project trial assessed the response to nitrogen and sulphur in canola crops of the Riverine Plains by determining:
• the influence of nitrogen and sulphur application on canola tissue content, yield and oil
• the fluctuation in nitrogen and sulphur content and nitrogen:sulphur ratio in the plant from stem elongation (GS31) to harvest (GS99)
• the optimum available soil nitrogen level for the region’s canola crops at varying sulphur application rates.

The aim of this work is to understand the impact of stubble retention on in-canopy temperatures and associated risk of frost in cropping environments with high yields and high stubble loads.
