This project sought to maximise the profitability of barley in the northern Geraldton Port Zone by providing information to growers to allow them to make informed decisions around barley variety choice, sowing time, in season management and management of their rotations in order to maximise barley productivity and improve the overall profitability of their farming business.
The project sort to answer specific questions of -
Do barley’s have specific adaptation which can be exploited.
Can varieties attain malt quality in the Geraldton Port zone.
Do variety maturity and planting times influence yield and grain quality, particularly with early sowing opportunities.
Does barley out yield wheat, sown early, or sown late.
Was barley profitable compared to wheat.
Can early sowing of short season varieties provide a maturity window and low risk option to avoid late season hot/dry finishes and produce a profitable yield.
To gather data on barley performance when late sowing on ameliorated soils. Can barley provide a more profitable option than wheat for late sowing on ameliorated soils?
Gain a better understanding of nitrogen management with different rotations or soil types (including soil amelioration) for barley yield with feed quality and for malt production.
Did barleys differ in their response to nitrogen.
Can early sowing and fertilising for high yield feed deliveries be more profitable than wheat.
Did project sample an adequate range of seasons.
The project “Barley Agronomic Strategies for the Geraldton Port Zone KAL2003-002SAX \ 9178054” demonstrated that barley can be successfully grown in the Geraldton port zone and it can compete successfully with wheat. Varieties that performed well over years were identified at each location and these varieties matched the yield of wheat and in many instances recorded a significant yield advantage. This is most likely when barley is sown early.
Malt grade barley can be grown successfully in the Geraldton port zone, yet it cannot currently be delivered to CBH facilities.
Barley cannot compete with wheat financially as the first choice cereal in a crop rotation. The yield benefit was not large enough to overcome the price premium for wheat in the duration of this project.
Under the growing conditions and treatments experienced in this project it is clear that varieties respond in a similar manner to the way nitrogen is applied, therefore crop nitrogen strategies need to just consider crop growth stage, paddock history and expected growing season, not the variety.
In general, applying all nitrogen up front, prior to seeding, was a robust nitrogen strategy for the yellow sands at Binnu and the loam soils of Northampton, Tenindewa and Canna. An active nitrogen management was more likely to be beneficial at Eradu, Canna and West Casuarinas.
This project sampled three growing seasons. Whilst two seasons experienced many hot days above 30oC during grain fill no season experienced a very hot / dry finish that can occur in the Geraldton Port Zone.
The experimental design for each site consisted of a split-plot design for each time of sowing (TOS), with Variety nested within Nitrogen along each column. Two-directional blocking was used to account for spatial variability.
