Development of best management practices to increase the production of high-quality grade peanut kernels

This trial was designed as a scoping study to investigate various aspects of long coleoptile wheat relative to WA farming systems for eventual grower integration. However, this report outlines both observations as well as extensive data that was collected and analysed, despite the original aim of the trail to be more investigatory than data-driven in nature.
The main area of research was investigating the novel Rht18 gene in wheat, which allows for an elongated coleoptile: a protective sheath around the emerging shoot from a seed. Mace/Scepter typically have 40-60 mm coleoptiles (depending on environmental factors). New varieties developed by CSIRO with the Rht18 gene can extend to 12-140 mm by comparison.

This 2-year project has assessed long coleoptile wheat applications to farming systems in WA across emergence, establishment, weed competition, rhizoctonia impacts, herbicide interactions and yield. Extension across sites has aided in discussions with growers and areas requiring further study for integration to grower systems. While investigatory in nature, 2022 trials outlined in this report aimed to be more data driven in nature than trials conducted in 2021.

The two-year scoping study aimed to achieve the following objectives for investigate various aspects of long coleoptile wheat relative to WA farming systems for eventual grower integration:
• Extend long coleoptile findings and discussions to growers across agricultural regions of Western Australia
• Quantify differences in emergence from deep and shallow sown varieties with varying coleoptile lengths.
• Investigate emergence through furrow fill from wind and rain events.
• Investigate emergence from uneven soil platforms, such as from deep-ripping
• Investigate emergence through both low and high soil temperatures.
• Explore biomass and vigour differences between varieties with and without the Rht18 gene.
• Quantify differences in annual ryegrass competition and wheat vigour interactions with grass weeds.
• Explore herbicide interactions across depths of sowing to investigate crop safety and ways of adjusting/changing IBS and EPE herbicides.
• Explore rhizoctonia wheat root infection between depths of sowing.
• Analyse grain yield of various varieties and coleoptile lengths, including Rht18 wheat.

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.

To investigate barley management options to close the yield gap and reduce pre-harvest losses

This investment will deliver a series of field trials and extension activities to reduce the yield gap between attainable yield and water limited yield potential in barley in the low – medium rainfall zones alongside virtual trial treatments derived by crop models to determine new attainable yield benchmarks for barley growers.

The aim of this project is to improve the capacity of growers to identify and manage subsurface acidity on the Northern Yorke Peninsula. Soil testing and pH mapping for acidity has become common practice in the district. However, this sampling and mapping has focused on the top 0-10 cm of soil. Recent reports and preliminary work have confirmed an acidic band of soil is often occurring at the 5-15 cm depth and beyond in certain soil types.

There are two main components to this project:

• Spatially identifying subsurface acidity by validating the relationship between soil pH and EC (electrical conductivity).
• Develop best management practices for lime amelioration to manage subsurface acidity.

Native budworm actively feeding on cereals has not been an issue for growers or industry in the past, and considering the recent detections, growers and western region industry networks have voiced that they would like support on this issue, especially regarding sampling techniques and spray thresholds. To achieve this, we investigated this new behavioural trend and the population numbers required to cause economic yield losses to determine if and when management is required in non-traditional cereal hosts.

Through pheromone-based moth trapping, crop inspections, glasshouse trials and a field cage trial, we investigated the behaviour of H. punctigera moths and larvae on, and potential economic damage to, wheat in the northern grainbelt of Western Australia.
