A clear look at the years of selection behind a better grain variety.
GRDC In Conversation with James Walter follows the path from a cross in a glass house to a new variety that is better placed to handle difficult seasons.

Applied grain research, straight from the field.
GRDC Podcast is a steady, field-focused interview show built around Australian grain research and extension. Episodes turn agronomy, market access, automation, plant breeding, and grower experience into practical context for farm decisions.

GRDC Podcast is a practical interview series for people working in and around Australian grain production. Its centre of gravity is the farm decision. Episodes take research and extension work that could easily stay inside reports, trials, and industry updates, then put it into conversations about growers, costs, yield, risk, and seasonal pressure. The show is especially strong when it sits with complexity. Pulse production is not presented as a simple opportunity; it is discussed through herbicide safety, weed competition, sandy soil constraints, market access, break crop benefits, and the economics of getting establishment right. Marketing episodes consider collaboration, volume, price discovery, and whether growers gain anything by approaching buyers together. Agronomy episodes stay close to paddock realities. Sandy soils become a discussion about strength at depth, non-wetting surfaces, water holding capacity, acidity, and why different constraints need different responses. Weed management is treated with the same care, especially in lentils where herbicide choice, resistance pressure, crop injury, and yield penalties all matter. The show also looks beyond single-crop decisions. Grain Automate episodes ask how growers can structure rainfall, yield, soil test, and other farm data so it supports action rather than producing unused dashboards. GRDC In Conversation adds a people-focused strand, following career paths through bioinformatics, field trials, grower groups, farming systems, and next-generation leadership in the grain sector. These profiles give the technical material a human frame. They show how plant breeding, trial reporting, extension, and grower learning actually happen through teams, seasons, and relationships. The pacing is measured and interview-led. Specialists are allowed to explain the route from problem to recommendation, often with enough detail to be useful to an informed listener who is not a specialist in that exact area. GRDC Podcast suits growers, agronomists, researchers, extension workers, and industry listeners who want applied grain knowledge with the practical caveats left in.
Made for: For Australian grain growers, agronomists, researchers, advisers, and industry listeners who want practical context around research, trials, markets, and farm technology.
What sets it apart: Its strength is the link between technical research and grower usefulness. Episodes keep returning to implementation: cost, risk, seasonal timing, and what a decision looks like on farm.
GRDC podcasts cover the latest grains research, development and extension knowledge and outcomes to help grain growers improve their profitability.

A clear look at the years of selection behind a better grain variety.
GRDC In Conversation with James Walter follows the path from a cross in a glass house to a new variety that is better placed to handle difficult seasons.
A practical GRDC Podcast episode on lentil weed control, herbicide precision, and resistance trade-offs.
Pulse crops can unravel fast when weed control misses the mark, and this GRDC Podcast keeps that risk tied to farm economics. The episode puts lentils at the centre, with trials pointing to yield losses of up to 80 percent from crop-weed competition.
A practical career story shaped by seasonal work, data, and the logistics of running trials across four states.
Darcy Warren's conversation with Ollie Lelieve follows a grain-sector career that begins at a university open day, moves through a graduate program backed by GRDC and Agriculture Victoria, and expands into trial work across Western Australia, Victoria, Tasmania, and New South…
Satellite weed detection focused on spray timing, cost, and less guesswork.
WeedSat comes across as practical ag tech, not a novelty. The focus is on spotting larger, harder to kill weeds from satellite images, and the conversation stays tied to farm workflow and cost.
A grounded look at autonomy as farm readiness, not shiny hardware.
Grain automation is presented first as a question of readiness, and only then as a machinery decision. Emma Lennard, from AgriKnowHow and Deal With Change, uses a quiz format to give people a score and a clear direction, then moves through the five foundational building blocks…
A grounded look at the data-heavy path from glass house crosses to better grain varieties.
James Walter, Bioinformatics Lead at Australian Grain Technologies, sets out how grain breeding decisions move from glass house crosses into field testing, with genetic and field data helping breeders decide which lines are worth carrying forward.
