Can you bank nitrogen in Western Australian soils?
Issue 164, May-June 2023 - 05 May 2023Working with 20 growers from GRDC’s National Grower Network, Dr Darren Hughes from Laconik has been investigating the nitrogen banking capacity of Western Australian soils following frosted crops. Unfortunately, it is not a source of nitrogen to be relied upon.

Crop competition can reduce weed burden and increase yields
Issue 164, May-June 2023 - 04 May 2023Six years of research indicates increasing crop competition by using narrower row spacing and/or increasing crop density has great potential to reduce both weed pressure and herbicide use.

Growing appetite for plant-based foods
Issue 164, May-June 2023 - 26 Apr 2023In recent years, research has emphasised the health and environmental benefits of a diet rich in plant-based foods and reduced animal-based food consumption. This research has coincided with the rise of flexitarian eating, which has become more popular among Australians.

Australian geneticists leading the way in new traits
Issue 164, May-June 2023 - 25 Apr 2023A team of researchers from Western Australia has successfully used new gene-editing techniques to develop nitrogen use efficient barley lines – and they have now set their sights on wheat and other crop traits. Yield potential, flowering time and plant height in both barley and wheat are among the new individual traits being fast-tracked for breeding programs.

Neonicotinoid resistance in green peach aphids: a setback for seed treatments
Issue 164, May-June 2023 - 24 Apr 2023New research from Cesar Australia investigating the implications of neonicotinoid resistance in the green peach aphid (Myzus persicae) could change how and when these chemical treatments are best used in broadacre crops. The green peach aphid is a species of particular concern to the grains industry, as it acts as the main vector of a number of economically damaging plant diseases, such as turnip yellows virus (formerly known as beet western yellows virus) in canola and pulse crops.
