To examine the yield potential of new winter and spring germplasm grown under HYC Management packages against spring and winter controls in the traditional late April/early May sowing window.

ï‚· The highest yielding spring cultivar at 9.76t/ha yielded similar to the control RGT Planet at 8.72t/ha while Rosalind was lower yield at 8.35t/ha
ï‚· The highest yielding 2 row and 6 row winter barley was Newton at 7.13t/ha and Pixel 7.43t/ha respectively (shaded green in table below).
ï‚· Proteins were in the range for malting however test weights were low suggesting some weather damage these ranged from 63.3 – 68.3 in spring cultivars, and 60.4 – 67.7 in winter cultivars.
ï‚· The phenology responses range from the earliest flowering in the spring cultivars Rosalind on the 11th September and Planet on the 19th September.
ï‚· Winter cultivars developed slower with the fastest winter being Urambie flowering on the 30 September through to the 17th October in Newton
ï‚· Despite flowering at a more optimum time for Millicent yields were lower from later flowering. This was due to a combination of reduced light limiting potential yield and head loss and lodging were the major causes of yield loss in the winter cultivars.
