Novel management strategies to reset barley development locations
Aims

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?

Key messages

 Cultivar choice had the biggest influence on head densities. Rosalind reached 965 heads/m2, Planet 746 heads/m2, and Urambie 820 heads/m2. This reflects the genetic ability of these cultivars to tiller and the proportion of tillers that survive.
 Similar yields were achieved at low and higher plant densities, consistent with findings from other experiments that demonstrate limited yield responses at target densities above 150 seeds/m2
 Defoliation reduced yield on average by 0.5t/ha.
 Defoliation at GS32 in Rosalind corresponded to a defoliation date of GS31 in RGT Planet and later tillering in the winter cultivar Urambie
 Despite the later than recommended defoliation date in Rosalind there was a significant delay in crop development. In other experiments Rosalind has responded well to this treatment and in frostier environments or in higher production environments years it may be possible to increase yield with this strategy from earlier planting dates.
