HYC PGR x harvest date interaction locations
Aims

To assess the value of PGRs with delayed harvest in HRZ regions

Key messages

 When harvested on time RGT Planet achieved a grain yield of 8.8 t/ha significantly higher than the winter cultivar Cassiopee at 6.6 t/ha.
 Delaying harvest timing by 3 weeks resulted in a significant yield penalty of 2.2 t/ha and 1.7t/ha in RGT Planet and Cassiopee respectively. This highlights the importance of harvesting barley in a timely manner.
 Applications of PGRs did not increase yield when harvest was delayed at this site in 2020. A significant weather event occurred prior to the timing of harvest in the ‘on time’ treatments which may have masked some of the treatment effects.
