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

Are we better to increase seeding rate and reset phenology in faster spring Barley sown early to capitalize on root growth, greater carbohydrate reserve, and initiate more tillers rather than utilise current winter germplasm options sown early in the HRZ? Is spring barley more sensitive to changes in plant density than winter barley?
