The demonstrate issues key to the current GRDC funded Stubble Initiative Project.

In 2012 the UNFS attempted to validate this early work conducted by the CSIRO. Seed of a long season variety Eaglehawk was sourced. This variety is Prime Hard Quality in NSW and so would be AH in SA.The aim was to conduct a time of sowing trial using three varieties at three times of sowing:- an early maturing variety (Axe), mid season maturing (Frame) and late maturing (Eaglehawk). Ideally the three sowing times were to be 1) mid April 2) early to mid May and 3) early to mid June.

This one-year investment aimed to provide growers and advisers along the South Coast of WA with greater confidence to make decisions on whether to sow a cereal crop later in the growing season (late winter, early spring) after crop failure, or inability to seed, due to early season waterlogging. It also aimed to provide some data on what varieties and nitrogen fertiliser strategies might be required for later sown crops.

This investment aimed to locally validate previous R&D investment relating to spring sown crops (albeit include newer crop types and varieties where suitable), building local grower and adviser knowledge to inform decisions when managing excess soil moisture. It aimed to provide production and economic information from both farm-scale demonstrations and a small plot trial to inform good business decisions in regard to spring/summer sown crops.

The trials evaluated the crop performance on a range of metrics to provide a thorough assessment of summer crops, and the role they can play in agronomic systems, and the potential they have to reduce the waterlogging risk.

GRDC Outcome:

By February 2023, 20% of Western Region Growers who farm in areas with a medium to high-risk of regular waterlogging will have built the knowledge and confidence to profitably sow a crop in spring or summer on paddocks were winter crops/pastures have failed due to excessive waterlogging or where soil moisture levels permit in future years.

To achieve this outcome, Stirlings to Coast Farmers (SCF) worked with a number of other Grower Groups to ensure the key learnings of the trial were broadly and successfully extended to growers in the Great Southern Region of WA.

The trial aims to explore management options for non-wetting soils in the Albany port zone.

Conventional methods of managing non-wetting soils involve mechanical disturbance to mix non-wetting particles with wettable particles. This trial explores the best options for placement of wetters, and wetter types for managing non-wetting soils.

Eleven treatments of differing placements and rates, as well as three seed placements were explored and analysed in this trial.

Two market available wetting agents were tested in this trial, SECOA’s SE14 and BASF Devine.

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.
