Dryland Legume Pasture Systems: Grazing trial locations
Aims

In southern Australian mixed farming systems, there are many opportunities for pasture improvement. The Dryland Legume Pasture Systems (DLPS) project aims to boost profit and reduce risk in medium and low rainfall areas by developing pasture legumes that benefit animal and crop production systems. A component of the DLPS project aims to quantify the impacts of different pasture
legume species on livestock production and health. Included are widely grown legumes (strand medics and vetch) and legumes
with reasonable prospects of commercialisation (trigonella).
A five-year grazing system trial was established at the Minnipa Agricultural Centre (MAC) in 2018. It is the main livestock field site
for the DLPS program in southern Australia.

Key messages
  • Pasture legumes sown in 2018 were allowed to regenerate in 2019 and were grazed with ewe hoggets.
  • Sheep live-weight increased on average by 13.8 kg (+26%, ~180 g/day) and was similar for all legume treatments, but differences between the sown legumes may have been masked by volunteer pasture species in the plots.
  • Sown legume intake ranged from 401 kg/ha (Trigonella balansae) to 1461 kg/ha (Harbinger medic). Sheep showed some grazing preference for medic over trigonella. 
  • The site will be sown with wheat in 2020. Crop growth, grain yield and quality will be measured. Stubbles will be grazed. It will return to pasture in 2021.
