The project will demonstrate time of sowing, best available varieties suited to the areas of the demonstration sites and season permitting, the opportunity for grazing without yield penalty. It is worth noting the 2020 season did not allow the opportunity to graze any of the demonstrations.  The project will also provide practical guidelines or agronomic packages for production of long season wheat in the medium to high rainfall zones of South Western Australia. The key outcomes of this project are:

• Demonstrate the yield potential of different long season wheat varieties relative to spring wheat varieties with an early sowing window
• Develop economic analysis comparing long season and spring wheat varieties and time of sowing regarding yield to assist producers in making informed decisions
• Begin the development of an agronomic package on growing long season wheats, time of sowing, seeding rates and fertiliser application and timing will be examined within this project.
• Develop protocols around the importance of time of sowing for long season wheat varieties that are best suited to different areas within southern Western Australia
• Where seasonal conditions allow, demonstrate the ability of sowing long season wheats to manage the feed gap in Autumn and winter through crop grazing with having minimal yield penalty

Muradup: Accroc was the highest yielding variety and appeared to be largely unaffected by the frost events yielding 8.40 MT/Ha. The other four varieties in the trial all appeared to be affected by frost with Zanzibar yielding 5.09 MT/Ha, Illabo 2.99 MT/Ha, Catapult spring wheat 2.12 MT/Ha and Denison 1.41 MT/Ha. 

West Muradup: Accroc was the highest yielding variety at 6.90 MT/Ha followed by Illabo, 6.70 MT/Ha then Catapult 6.66 MT/Ha, Denison, 6.26 and lastly Scepter yielding 4.50 MT/Ha

Kurrenkutten: Denison yielded significantly higher than the other 3 varieties followed by Yitpi and Vixen which both yielded significantly higher than Rockstar.  

Mount Walker: Statistical analysis was determined between the varieties and demonstrated Scepter and Denison yielded significantly higher than Rockstar. Denison and Kinsei yields were not significantly different and Scepter was significantly higher than Kinsei.
