Abstract

Tedera (Bituminaria bituminosa var albomarginata) is a perennial legume herb showing promise for inclusion in mixed farming systems of Australia. In this research we compared two tedera lines with lucerne and an annual legume pasture at two sites in southern Australia, and developed an APSIM module to simulate tedera growth. Simulated tedera production was about one third that of lucerne in both wet and dry years. Tedera was also not as effective as lucerne, but more effective than sub clover, in extracting subsoil water. However, one of the tedera lines appeared to be particularly effective in extracting soil P, suggesting that (a) there is variation within tedera germplasm for P efficiency, and (b) that some tedera lines might be well suited to soils of low P status.
