HYC PGR x harvest date interaction locations
Aims

To assess the value of PGRs with delayed harvest in HRZ regions for its effect on grain yield losses due to harvest timing, lodging, head loss and brackling.

Key messages

RGT Planet yielded higher (7.03t/ha) than Buff (5.34t/ha).
Harvest timing had a significant effect on grain yield reducing yield by 1t/ha in both Planet and Buff with a 12 day after harvest ripe.
Moddus applied at GS31 only, and the combination of 200ml/ha at GS31 and GS37, yielded similar to the treatment which included Ethephon at GS49.
All PGR timings yielded similar to untreated irrespective of harvest date, however this has not been the case in previous experiments. In previous seasons harvest delays of greater than 14 days has resulted in greater yield losses in untreated plots compared to PGR
treatments.
