Aims

To examine the yield potential of winter and spring germplasm (cultivars/lines) grown under a HYC high input management package against spring and winter controls sown in mid-May.

Key messages

• Although set up as spatially separate trials (with some differences in varieties tested) the mean yield of the second time of sowing (12 May) was over 1t/ha higher yielding than the first time of sowing (17 April).
• At the second sowing nine varieties exceeded 10t/ha compared to only five varieties at the first time of sowing.
• A number of the winter wheat varieties exceeded 10t/ha at the mid May sowing with AGFWH004718 almost hitting 11t/ha.
• RGT Accroc which was subject to considerably less STB pressure than the first sowing date yielded 10.62t/ha compared to only 8.71t/ha when sown in mid-April.
• Although harvest dry matters were lower in 2020, the harvest index for RGT Accroc was 58% using a typical harvest dry matter (9.29/16t/ha at 0% moisture).
• At this sowing date the gap between the best feed wheat and milling wheat (Scepter) was approximately 2t/ha.
• 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).
