Abstract
Thirty one perennial legume and three herb cultivars/lines sown near Manilla on the North West Slopes in northern New South Wales, Australia, were assessed for seasonal herbage mass for 2 years after establishment. Medicago sativa subsp. sativa (lucerne) cv. ‘Sceptre’ had predicted herbage production that was higher than all of the cultivars/lines evaluated in seven of the eight seasons that it was tested, ranging from 557 kg DM/ha in autumn 2005 to 3803 kg DM/ha in summer 2005. Cullen australasicum and Dorycnium hirsutum generally had consistently good performance, followed by Cichorium intybus cv. ‘Puna’ and Astragalus suberosus, but did not match that of ‘Sceptre’. The clear superiority of ‘Sceptre’ lucerne in most seasons indicated that research should be targeted to overcome issues of bloat risk and low ground cover that restrict the use of lucerne in the region. Comparisons of two M. sativa subspecies highlighted variation that warrants further investigation.
