Lupin yielded 3.0 t/ha and canola 2.0 t/ha from late May emergence. Lupin gross margins were competitive with canola, and lupin gave the highest return on investment. For both lupin and canola variety selection was important, in particular Jurien lupin performed well from all sowing dates....

Control of wild radish in crop at stem elongation killed late emerging cohorts. An average of 97% of wild radish seed pods developed on the plant at a height greater than 30 cm, highlighting the value of capturing wild radish seed for harvest seed destruction. Due to the continuous emergence of wild radish seedlings throughout the year an effective...

The most common roadside summer weed species surveyed were African love grass, windmill grass, fleabane and wild radish. The four most common species in each region varied between years. Some prominent summer weeds are also winter weeds (like wild radish and wild oats)....

Tools that improve the accuracy and decrease time spent on pest and disease diagnosis will give growers a better ability to spray pesticides when and where required, saving them money on unnecessary sprays and reducing the risk of further development of pesticide resistance in pests and diseases....
-
Crop growth and grain yield were increased consecutively for 2 years as a result of deep ripping in yellow deep sand with multiple constraints. On compacted and acidic yellow sand the combination of lime sand with appropriate deep tillage will potentially minimise multiple soil constraints....

Within an environment, wheat cultivars did not differ in their yield response to a change in density or added nitrogen in a majority of trials conducted in 2015 and 2016. Wheat plant densities of less than 100plants/m2 will limit grain yields for cultivar’s sown in early to mid-May. There is no consistent evidence that increased density to 200plant...
-
Disease expression increased with the susceptibility of the varieties, resulting in correspondingly higher yield loss.Losses were between 0.5 and 4 t/ha, depending on the type and severity of disease and the yield potential. Partially resistant varieties differed in the extent of their yield loss corresponding with lower disease expression....

WA oat varieties showed good tolerance to trifluralin at the permit rate (Permit Number 84040) and its mixture with terbuthylazine at label rate when incorporated by seeding with knife-points and press wheels seeding system. Oats should be sown at a speed between 4.5km/h to 9km/h to avoid crop damage....

When crop responses to treatments are highly variable, drone imagery can be an efficient method for measuring crop growth. Crop ground cover measurements on individual plots using drone images provide superior information compared to manual plant counts. Drone imagery can provide data that would previously require destructive measurement techniques...

Neutralisation of acidic subsoil is the most effective way to reduce aluminium toxicity to plant roots. Root proliferation in the acidic subsoil was increased by soil amendments only where they were incorporated into the subsoil, but not when applied to the topsoil. High rates of biochar mixed through the subsoil were effective in neutralising acid...
