Researchers in southern Victoria are taking to the skies to see if unmanned aerial vehicles (UAVs) can be used to help growers make timely interventions in canola establishment... Three sites were set up across southern Victoria in 2015 at Rokewood, Inverleigh and Winchelsea... There were six stages involved in the image processing: collection of colour infrared images; colour, texture and shape used to identify plants and create a binary image; self-learning algorithms used to detect larger and average-sized plants; the same algorithms then modified to detect small plants; the two images put together to calculate totals; and calculation of ground cover...

Project No.: DAW 672 Paper reviewed by: David Minkey and Abul Hashem Crop Updates is a partnership between the Department of Agriculture, Western Australia and the Grains Research & Development Corporation 20.. The negative impact of Raptor and Spinnaker on herbage production observed in the 4 advanced breeding lines (Crop Updates 2004) was not reflected as lower seed set... Overall, 2,4-D and Gramoxone were the most damaging to legume seed production; this reflected the impact of these treatments on herbage production (Crop Updates 2004)...

The comparison of chaff carts, windrow burning and HSD systems at 12 WA wheat belt sites during the 2010 harvest found that all three systems resulted in 50% reductions in the autumn emergence of annual ryegrass populations... To evaluate and demonstrate the HSD system across a range of crop production environments, the HSD and accompanying header were taken on the road across the WA wheat-belt during the 2010 harvest... To demonstrate the HSD system, local crop producers were invited along to each site where they were provided a description of the HSD system and its efficacy in previous research trials...
