The Participatory Action Research (PAR) process identified phosphorus (P) management as a priority amongst the grower and advisor community. With nitrogen work underway, P is the next largest, unavoidable expense for growers. In the target area (wider Griffith region) many of the soils have Colwell P values >40 mg P/kg soil.

This 3 year project aims to help determine the legacy benefits of a pulse crop to the following crop in the rotation and in particular which pulse species leaves the best legacy in terms of nitrogen benefit, disease pressure, water use efficiency as well as crop sequence gross margins.

As part of the NSW ARG, and as part of the Nitrogen Theme, Ag Grow Agronomy set up a nitrogen (N) systems trial in 2023 to test the performance of different nitrogen management strategies over a four-year period.

In its last year, our trial is investigating the effect of management factors such as sowing depth, press wheels and soil wetter (SE14) on canola establishment.

There was a need to validate the issue of acid soils that are anecdotally unresponsive to lime in western NSW so that crop yield gaps can be reduced.

The project aims to get a better understanding of the adaptability of pulse species to the local environments and how to improve production and close the yield gap of the best adapted pulses. The project is now in its 4th year.

Newer varieties being developed, with long coleoptiles, have the potential to overcome the limitations of sowing depth that current varieties with short coleoptiles have (limit approximately 4cm).

This information will be used to make selection decisions on varieties that offer growers advantages over currently grown varieties and variety progression through the breeding program and commercial release.

These trials compare the performance of wheat lines for yield, grain quality, agronomic attributes and disease reaction for all major production environments in Australia.

These trials aim to compare the performance of potential canola varieties with existing canola varieties commonly grown on dryland in Southern NSW.
