Biserrula: Its fit in the system

Research output: Book chapter/Published conference paperConference paperpeer-review


Poor reliability of autumn breaks, short springs and drought have reduced the reliability of traditional annual legume species such as subterranean clover and annual medics. Lucerne has been used in many areas to at least partially fill the gap left by traditional legumes, but soil acidity can limit its adaptation and maintaining adequate groundcover in lucerne paddocks can be a problem in many instances. Over the past few decades there has been considerable development of annual legume species with improved adaptation to climatic and soil challenges. Both 2018 and 2019 have allowed assessment of production and survival attributes of a range of annual legumes under extreme drought conditions in the GRDC northern region. In both years, biserrula has exhibited the capacity to produce viable quantities of seed to facilitate ongoing regeneration. This paper reports on the seed production achieved by biserrula under drought conditions and also identifies other species as having considerable potential under such conditions. The principles of use of these hard seeded species in rotations is also briefly discussed.
