Aims

To assess the value of PGRs with spring sown barley in HRZ regions

Key messages

 RGT Planet achieved a grain yield of 9.57 t/ha significantly higher than Rosalind at 8.37t/ha.

 Delaying harvest had little impact on grain yield and were similar to crops harvested on time

 Despite a lack of response to a harvest delay, plant growth regulators still had a positive influence on yield but only when they were applied in a split treatment at GS31 and either GS37 or GS49. PGR applied at GS31 achieved a yield of 8.8t/ha and when applied in a split treatment achieved yields of 9.2t/ha

 These results require further validation in 2021 but have demonstrated there is little downside trade off with the use of PGRs in the higher rainfall zone and a GS31 and later application could be combined with the most effective fungicide timings.
