Project details
Status: Current
At a glance
- The project aims to enable widespread adoption of serradellas across SE Australia.
- There are a number of ‘best-bet’ serradella cultivars that could be adopted on-farm almost immediately.
- This project will address key gaps in knowledge regarding how to establish and manage serradellas.
- Researchers will partner with farmer groups to deliver an integrated research/adoption program.
Why Serradellas?
Serradellas (Ornithopus spp.) are the only viable, near-term alternative annual legume species adapted to the key grazing region of South-East Australia, yet they remain underutilised due to a lack of knowledge and farmer experience in these permanent pasture areas that typically rely on subterranean clover.
After more than 8 years of research ($7.5M investment) into development of P-efficient pastures driven by MLA, there exists a small number of ‘best-bet’ serradella cultivars that could be adopted on-farm almost immediately. Serradellas have several mechanisms to mitigate drought risk compared to subterranean clover including deeper roots, smaller seed size and indeterminate growth habit, as well as lower P fertiliser requirements.
Partnering with industry
Researchers will partner with farmer groups to deliver an integrated research/adoption program that validates previous research, answers technical questions raised by growers and builds confidence that the serradellas offer the necessary persistence in these new environments where a changing climate threatens existing production systems.
This project will prove that serradellas are a species with widespread utility and production benefits that can be captured when they are used to replace, or augment subterranean clover.
Addressing knowledge gaps
This project will address key gaps in knowledge regarding how to establish and manage serradellas in permanent pasture environments, and appropriate cultivar selection.
Field experiments
‘Best-bet’ cultivars will be tested across four locations:
- NSW: Northern Tablelands, Southern Tablelands, Monaro
- TAS: Midlands
These locations represent significant but diverse areas of the permanent pasture zone of SE Australia. Modelling will be used to predict cultivar suitability across wider areas of temperate SE Australia.
Further field experiments in southern NSW will be used to generate guidelines for the establishment and management of serradellas in permanent pastures (e.g. sowing rates, seed scarification treatments to overcome issues with second year regeneration, herbicide options, feed value, P fertiliser management).
