HYC Elite Screen (Comparison of 21 April and 12 May sown)

Key messages

 For the first time in HYC trials on the mainland, wheat yields exceeded 12t/ha at the SA Crop Technology Centre.
 With a softer finish than 2020, later developing northern European winter wheats fulfilled their yield potential for the first time at the SA research site at the April sowing date, with Reflection and Tabasco yielding over 12.5t/ha along with a coded
line AGTW005.
 Despite the HYC higher fungicide input, these two cultivars (Reflection and Tabasco) were noticeably more resistant to leaf rust in the lower Southeast SA environment.
 Of those cultivars that are commercially available in Australia, the winter feed wheat Big Red (AGFWH004718) was the highest cultivar in both 2020 (10.94t/ha) and 2021 (11.45t/ha) in April sown HYC trials.
 Although set up as spatially separate trials on the same research site, the winter feed wheat Anapurna gave higher yields sown on 12 May than on 21 April (11.87t/ha vs 11.30t/ha).
 With second sowing date on 12 May, Rockstar significantly outyielded all other spring milling cultivars, however its overall yield was approximately 2t/ha or 19% lower yielding than the feed wheat Anapurna sown at the same time.
 If Anapurna feed wheat was priced at $275/t then Rockstar would have required a $57/t premium to achieve the same margin using the yield differentials in the trial.
 With the earlier sowing where Big Red achieved 11.45t/ha, the premium necessary to match the output would have dropped to $45/t (assuming quality could have been achieved with the milling wheat).
 Protein levels (11% plus in most varieties) and test weights would indicate that optimum yields were generated with the level of nitrogen applied (120kg N/ha).
