The Hyperyielding Crops project was rolled out across mainland Australia in 2020 with canola sites at Wallendbeen, NSW; Gnawarre, Victoria; and Millicent, South Australia. The aim of the project for canola is to determine the management strategies that achieve 5t/ha of canola in these environments. The primary management strategies investigated in 2020 included, cultivar choice, nutrient management, disease management and plant density. Yield of the best treatment in 2020 was >5t/ha at Wallendbeen and just below 5t/ha at Gnawarre and Millicent. The highest yielding treatment was generally at least double the yield of the lowest yielding treatment at each site. Cultivar choice was the single most important influence on yield variability at all three sites, on average accounting for 2 t/ha difference in yield. Nitrogen management was the next most important influence on yield, accounting for an average 1.2 t/ha difference in yield. Fungicide response was small at Wallendbeen (0.3 t/ha) and Gnawarre (0.2 t/ha) and not significant at Millicent. Where there was a yield response to fungicide recorded it was difficult to attribute the yield loss to any one disease. Plant density had no impact on yield at Wallendbeen and Gnawarre but there was a small penalty from low (<15 plants/m²) at Millicent. Similar trials incorporating an early sowing of winter canola will be included at the three sites in 2021 as well as at Frankland River in Western Australia.


Rohan is an agronomist and farmer with Brill Ag (since 2020) at Ganmain in southern NSW with current research, development and extension projects in canola and pulses.  Previous to this, Rohan was an agronomist with NSW DPI at Wagga Wagga, focussing on tactical canola agronomy.
