Harvest Weed Seed Capture in the HRZ locations
Aims

The aim of this project is to see if harvest weed seed practices can be adopted to reduce soil weed seed banks in high yielding high rainfall zone (HRZ) areas of the southern region to address herbicide resistance issues.

Key messages

Weed seed data (weeds above and below the harvest height) measurements were taken immediately prior to harvest and assessments of weed populations in the soil will be taken after autumn treatments (windrow burn and large scale burn) are applied to allow for an understanding of the effects of different treatments on the weed seed bank.
Harvest data was also collected through the yield monitor. This data is being analysed so that the additional cost of the iHSD can

Leaving straw in windrow to be burnt Weed seed data (weeds above and below the harvest height) measurements were taken
immediately prior to harvest and assessments of weed populations in the soil will be taken after autumn treatments (windrow burn and large scale burn) are applied to allow for an understanding of the effects of different treatments on the weed seed bank.
Harvest data was also collected through the yield monitor. This data is being analysed so that the additional cost of the iHSD can be established to run various economic simulations on the weed seedbank through the LUSO model and to compare the cost of the treatments. There was no significant difference in the yield across treatments or the efficiency (ha/hr). This was as expected as
the groundspeed rate was kept constant between all treatments so that the other factors.
