The Central West and East NSW sub-regions has some of the lowest relative crop yields in Australia and this investment seeks to reduce these yield gaps in these Central NSW subregions and lift averages closer to nearby locations and regional averages. GRDC seeks to address this with a 5-year investment to identify and benchmark current practices in the Central NSW sub-regions to close yield gaps. These plans will be tailored to local conditions, addressing agronomy, soil and water limitations, crop protection, and leveraging professional agronomists, research, and extension resources to enhance productivity and profitability in Central NSW.
This investment will unpack opportunities to close the yield gap by examining key decisions made on farm which are associated with nutrition (soils and crop), crop protection (pest weeds and diseases) and planting (crop and seasonal influences). Additionally, hyper-yielding aspects will be examined to understand the unconstrained yield potential, establishing a performance benchmark. Similarly, resource efficiencies (including water use efficiency and carbon/emissions intensity) will be considered to understand environmental and sustainability aspects. These elements effectively represent five workstreams which will be undertaken throughout the course of the investment with a sixth area to investigate sustainable options for retaining and building agronomic services and extension capacities and capabilities in the sub-region for the longer term.
This investment should be designed to examine key decisions on farm in relation to these five workstreams and facilitate a ground up approach to direct investigations that more effectively link with current and latest research yet validated locally. The participatory approach with growers and advisors will increase engagement and adoption by first establishing issues that are most relevant to those targeted by the investment; and then working collaboratively to develop new practices to address the challenges associated with these issues. Staging needs to include the following phases across the five workstreams:
- identify issues and constraints with farmers and advisors (relative to each workstream) and identify key bottlenecks and levers contributing to yield gaps,
- identify existing research that informs issues and consider localisation of this work,
- develop new practices and facilitate adoption (local action plans) by working collaboratively with researchers, advisors and farmers
- implement action plans, observe and make refinements
- progressively monitor and evaluate project outcomes.
Peer-to-peer learning and the guidance of research and consulting agronomists play a key role in helping growers understand and implement behavioural and practice changes. This investment will integrate the best and most current knowledge on systems agronomy and insights from the five workstreams to assess potential risks and profit opportunities and align these with local action plans. It is expected the investment will also draw on existing capacity and capabilities existing outside of these sub-regions to support innovations. Approaches to include on-farm trials and demonstrations, supported by robust agronomic data collection, facilitated and informed decision-making discussions and monitoring and evaluation of these decision support and extension activities. On-farm trials will be aligned with the latest in standardised approaches to paddock scale experimentation (where possible).
Regional strategies (supported by localised action plans) will have a stop/go point within the first year of the investment to ensure these are targeted, have clear research questions established and linked to existing (eg: National Paddock Survey data) and emerging research developments and investments. It is expected the investment will work collaboratively with farmers and advisors and overcome localised issues and constraints in developing regional strategies and localised action plans that are fit for purpose for farming practices. These are to be continually reviewed and refined to build the knowledge and confidence of growers to underpin and support practice change leading to adoption.
Growers are to be actively engaged through local sites where they can compare results and access updated information with traditional and non-traditional dissemination activities and tools used to used ensure growers and agronomists can easily follow progress and participate in discussions. Detailed agronomic measurements will enable comparisons between forecasted models and actual outcomes based on seasonal conditions allowing growers to evaluate best management practices in relation to real-world conditions in their local area.
Extension activities are to support knowledge for decision making and adoption and rely on multiple channels including but not limited to usual activities such as field walks, presentations, technical manuals, webinars, and podcasts. A detailed monitoring and evaluation plan will be developed to assess and measure progress and effectiveness of extension activities and monitor trajectories towards the 5-year goal of reducing yield gaps. This will be developed by a monitoring and evaluation specialist supporting the investment across the five years. These specialist services will sit parallel to or within the proposed services to be procured and will ensure consolidation of existing successful actions and efforts and/or pivoting to re-align activities to ensure local action plans are impactful for growers. Evaluation activities can be embedded into existing capacity and monitoring efforts, establish a new framework of action or be a mix of these that are commensurate with the investment and activities being undertaken.
The investment aims to directly engage a significant number of participants leveraging digital and online channels and proponents could consider the opportunity (if applicable) to test digital outputs, provide early user field experience and feedback of GRDC’s of digital extension investment, MyGRDC.
Reporting will include: i) annual workplan, ii) mid-year progress report and iii) annual results which will incorporate the five workstreams with reporting on evaluation of extension activities that draws on metrics of grower engagement and participation rates and effectiveness. Supporting or secondary indicators can be investigated to support impact measurements over time. For example, the potential use of CSIRO’s annual crop performance and yield gap analysis data (APSIM and APSIM NG) to monitor changes to regional and sub-regional averages over the investment. This investment aims to maintain and build on existing development and extension activities across Central NSW, providing growers and advisers with access to new and essential cropping information through various channels. With the goal of reducing yield gaps by maximising the effectiveness of grower engagement, proposals who seek collaboration and linkages across farming system groups to identify and implement the best farming practices that will lead to improvements in productivity and profitability will be looked upon favourably. GRDC encourages collaborative and multi-party proposals including the required diversity of expertise for the scale of this investment or indicate the willingness to work with a variety of parties and clearly articulate how these linkages will work operationally.
