Optimising sulphur and nitrogen nutrition in canola

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.

Optimising profitability of high rain fall zone farming systems.

By 2023, growers will have increased the value of the cropping phase in the HRZ farming system by 10% by addressing both crop yield potential and the gap between potential and realised yields.

This trial aims to explore ways to optimise crop production in the HRZ. 
This trial looks at verity types, deep ripping and sowing times as ways to maximise yields in the HRZ. 

This trial aims to assess different treatments and there effectiveness in maximising water limited yield potentials.

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).

Optimising fungicide strategies for more disease susceptible wheat cultivars

With the large majority of wheat cultivars now deemed to be susceptible to stripe rust, in particular the new WA pathotype, this trial was set up to look at economic response to different foliar fungicide timings. In addition the trial continued the evaluation of the strobilurin fungicides (as part of project SFS 00006), the first of which was registered for broad acre cereals in Australia in August 2004 (Amistar Xtra).
