To assess the value of PGRs with delayed harvest in HRZ regions.
• The harvest date trial in the first time of sowing was sown into plots of Pixel, a 6-row winter barley known for potential head loss at crop maturity.
• Although there was no significant interaction between PGR management and harvest date, there was a trend for a delayed harvest to decrease yield by 1.59 t/ha.
• Both a double Moddus Evo application and the ‘European’ PGR approach were higher yielding than the untreated, however a single application of Moddus Evo on average was higher yielding that the other PGR managements.
• The combination of Pixel with a single Moddus Evo application and harvesting on time gave the highest barley yield on site (8.43 t/ha).
• Harvest date and PGR management had very little impact on grain quality with the exception of improved test weight with an on-time harvest.
