Wheat in the most diverse rotation is now consistently producing more grain (by about 0.2t/ha), with consistently higher grain protein (by about 1.6%), compared with the continuous wheat treatment. Residue windrowing and burning has reduced residue levels by about 50%, which has had an inconsistent impact on crop yield and has decreased wheat prote...

• Green on green camera technologies is now used on farms. This will lead to important financial benefits for growers but will also have impacts on farm management • Growers need to understand the benefits but also the limitations of these new technologies. This is only way it will bring real benefits....

This project has closely monitored numerous grain bags during the 2017/18 and 2018/19 harvest seasons to assess them for grain quality implications. In this process, the logistical and harvest management implications have been documented to understand best practice guidelines for all WA grain growers....

Feathertop Rhodes grass (FTRG) is already widespread along the sides of many of Western Australia’s major country roads. Studies on FTRG seed survival have shown up to 96% of the seeds germinated when tested at three and six months after burial at three depths. This high level of germination indicates that there may be limited dormancy of FTRG in t...

With a mid-April sowing, Bannister oats achieved a higher grain yield and gross income than wheat and barley in 2017 and was the highest yielding and gross income treatment of all sowing windows in 2018. With a late-May sowing, Bass barley achieved a higher grain yield and produced the highest gross income in frost-prone landscapes in 2017 and 2018...

Image analysis of field photographs taken with mobile phones attached to agricultural equipment has the potential to be used to economically make maps of snail distribution and density in a paddock. This data can be used to make snail management decisions that reduce their economic impact. Machine learning deep neural networks were used to produc...

Local sources of carbonate performed as well as limesand on an acidic eastern wheatbelt sandplain, in terms of yield, particularly in conjunction with cultivation. Cultivation with offset discs performed as well as deep ripping treatments, in terms of yield, in 2017 and 2018. Local carbonate sources raised the soil pH in the top 15 cm. Cultivation ...

Lacewing larvae kept green peach aphid (GPA) populations on caged canola plants the same or lower while the GPA populations in control cages increased substantially. Spotted ladybird beetles decreased GPA populations slightly during the first week but then GPA populations increased markedly but were still lower than controls. Parasitoid wasps were ...

Four field trials in 2018 assessed the influence of plant density, nitrogen timing and grazing on yield and quality of three long maturing wheat varieties sown early April in Western Australia....

Fungicide resistance to Group 3 (DMI) fungicides in spot form of net blotch is spreading in the southern region of WA....
