Twenty-one shrub legume accessions were grown at 2 sites in Indonesia
and 2 in Australia, and repeatedly harvested to estimate leaf and stem
production. Two fertiliser treatments (nil and complete) were imposed
at each site. There were major effects of fertiliser at the 2 most in
fertile sites [Silkwood (Australia) and Sembawa (Indonesia)]. No shrub
legume entry grew consistently well across sites without fertiliser.
Some species did not persist more than one year, but produced quite hi
gh yields. These included Cajanus cajan, Codariocalyx gyroides and Ses
bania sesban. These species may be of use as protein banks during the
establishment of more perennial species. Leucaena leucocephala did not
grow well at the 2 most infertile sites, and was badly affected by th
e leucaena psyllid at both Australian sites. Overall, the highest yiel
ding species were Calliandra calothyrsus, Acacia angustissima, Glirici
dia sepium, L. diversifolia and L. pallida. There was a good relations
hip between leaf production of entries at the 2 Australian sites, and
between the 2 very acid sites, but only with the fertilised treatment.
