Agronomic systems to improve profitability of wheat on wheat through disease and nutrition management at Binnu 2013 trial report

Please note: This content may be out of date and is currently under review.

In 2013 at Binnu, Mace was the highest yielding variety when sown on wheat stubble. Nitrogen application did not influence grain yield (t/ha) but did influence protein and grain weight (kg/hL). Fungicide application reduced disease levels which resulted in yield increases. Adequate nitrogen is not an alternative to fungicide but an additional measure to make plants less vulnerable to disease.

Background

Risk factors to the wheat on wheat systems are disease and nutrition.

The foliar diseases yellow spot (YS) and septoria nodorum blotch (SNB) are particularly high risk when wheat is sown on wheat stubble.

Variety choice, timing of fungicide and nitrogen are tools to manage this system.

To maximise fungicide return on susceptible varieties, studies indicate the need for optimum nitrogen nutrition.

This relationship needs to be tested on newer varieties with improved disease resistance for disease management in a wheat on wheat system.

Aim

Determine the value of nitrogen and fungicide on the profitability of new wheat varieties with different disease resistances in the wheat on wheat system.
