My role in the department

Dr. Dhammu is working as a researcher and project manager at DPIRD based at Northam. He investigates herbicide tolerance of new varieties of grain crops since 2000 with an aim to improve farm profitability by reducing yield losses due to herbicide damage. Dr Dhammu has also been working on quinoa agronomy since April 2018 with the possibility of releasing a new variety at the national level by 2021. He recently completed AgriFutures Australia funded project on “Quinoa as a new crop in Australia –stage 2” as a Principle Investigator and project manager.
