Lupin seed integrity and establishment
Lupin seed integrity and establishment With split seed resulting in yield penalties higher than 70% in some areas, a new GRDC investment is looking at how growers can manage their handling of lupin seed to ensure better germination of seed in the following seasons. A benchmark study of 27 WA growers looked at germination impacts for lupins, focusing on reducing the incidence of split seed through harvest activities such as machinery impacts, and manganese deficiency. The study which started in 2019 has now wrapped up, with advice around manganese management, going easy on the augers, harvesting with at least 12% moisture and asking the experts to assess seed. But those who know lupins, know there’s still a lot to learn.

S1 Ep 269Predicting Nitrogen cycling and losses in Australian cropping systems
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.

Ep 233Fungicide resistance in the north
Growers in the north could consider fungicide resistance less of a threat than growers in the south and west, however there is no room for complacency. As Professor Levente Kiss from the University of Southern Queensland’s Centre for Crop Health points out in this podcast, as long as there are fungal crop diseases there is a risk of fungal resistance. Barley, wheat and pulses can all be affected. Northern growers need to appreciate the importance of rotating and mixing fungicides, including as seed treatments, in order not to encourage fungicide resistance in important diseases such as barley net blotches, mung bean powdery mildew, wheat powdery mildew and septoria tritici blotch.

Ep 232Fungicide resistance in the south
South Australian grain growers have been alerted to several cases of fungicide resistance in recent growing seasons, including in net form net blotch of barley, and wheat powdery mildew. In this podcast, Dr Hugh Wallwork, from the South Australian Research and Development Institute, the Department of Primary Industries and Regions’ research division, talks about the factors that contribute to fungicide resistance and how fungicide management needs to begin with variety and seed treatment selection before sowing. He explains that growers should be using all available agronomic practices to reduce disease pressure and should avoid repeat applications of a single fungicide active or chemical Mode of Action. This will help protect the effectiveness and availability of their essential fungicide controls. Learn more about your ad choices. Visit megaphone.fm/adchoices
