GRDC Podcast

Weeds are one of the largest costs to Australian growers - affecting management, yields and input costs. That’s why GRDC is a platinum partner in WeedSmart - an industry led initiative designed to deliver weed control solutions.

WeedSmart is the united industry voice delivering science backed weed control solutions to growers and advisors for long term productivity in Australian agriculture.

To see the full list of financial, in-kind and international in-kind; and research partners visit this page.

We explore the WeedSmart initiative with WeedSmart Project Manager, Jessica Strauss and Chris Davey, Agriservices agronomist from YP Ag.

WeedSmart Week 2022 is happening in Mildura, Victoria from 30 August - 1 September.

Australia’s canola industry continues to grow from strength to strength - despite the presence of blackleg, a common disease that has the potential to cause more than 90 per cent yield loss.

This success story is thanks, in part, to decades of targeted GRDC investment into blackleg management – delivering significant genetic and agronomic advancements to help canola growers reduce the impact of this serious pathogen.

Marcroft Grains Pathology Principal Dr Steve Marcroft has been at the forefront of this research for nearly 30 years and he discusses the impact that blackleg research has had.

One of the greatest barriers to improving farm productivity in Australia is water.

Over the past ten years, GRDC investment in water use efficiency (WUE) research has resulted in significant yield gains and underpinned an evolution in the management of summer fallows and farming sequences across Australia’s southern and western cropping regions.

Southern NSW agronomist Greg Condon has been involved with WUE research projects for more than 12 years, and in this podcast he delves into the research findings that are delivering real impact for growers.

Excessive rainfall has hit northern growers over the past six months.

With water logging across paddocks, growers are at heightened risk of losing nitrogen from denitrification, and it’s an issue GRDC is keen to understand better.

Recent research supported by GRDC and led by Senior Research scientist at the New South Wales Department of Primary Industries, Dr Graeme Schwenke, found that on average, paddocks with waterlogging could lose 28 per cent of nitrogen from denitrification.

To get the complete picture of nitrogen cycling and the conditions under which growers can lose nitrogen from the soil, GRDC has launched a new project to investigate how to better predict nitrogen cycling and losses in Australian cropping systems with a focus on augmenting measurements to enhance modelling.

In this podcast Dr Schwenke discusses the state of play on the ground right now, and the value of further research into nitrogen cycling.

Long coleoptile wheat is getting a lot of grower interest and some new research been delivering some exciting results.

This genetic approach is focused on wheat lines that produce a long first shoot, or a coleoptile, allowing for deeper sowing into soil with residual moisture. After successful paddock-scale trials, the research is helping growers mitigate the risk of poor or failed establishment because of unpredictable summer rain and sowing breaks.

Led by CSIRO plant geneticist, Dr. Greg Rebetzke, we talk about the research that's got growers and the GRDC excited about the future potential of the long coleoptile wheats.

When it comes to maximising the productivity of irrigated crops, research is proving it isn’t as simple as adding water and lots of nitrogen fertiliser.

The Optimising Irrigated Grains project team have two seasons of impressive agronomy data under their belt –helped along by back-to-back mild spring conditions which has seen them achieve some pretty exceptional yields

A 90-day summer chickpea crop could soon be a reality for the north, giving growers a pulse option to plant in February and harvest in June.

Researchers involved in the summer chickpea project, made possible through GRDC investment, have spent the summer assessing the performance of 20 chickpea lines across five different locations.

As project lead Dr Angela Pattison from the University of Sydney explains, the trial results and yield potential of the system are showing real promise.

Fusarium wilt is significant mungbean disease that can result in up to 80 per cent yield loss.

In an effort to arm growers with information about this costly disease, the Department of Agriculture and Fisheries (DAF) in Queensland has set up a variety of tolerance trials across the state as part of a wider GRDC and DAF co-investment on optimising mungbean yield in the northern region.

In this podcast, DAF Extension Officer, Jayne Gentry, shares the latest research findings and her recommendations for managing fusarium wilt.
