| Abstract: | Nodules were collected from 14 legume species from the Indonesian Islands of South Sulawesi, Java and Sumatra. Their rhizobia
were isolated and growth characteristics, nodulation ability and nitrogen fixing effectiveness were assessed against recommended
commercially available Australian strains. The test legumes wereMacroptilium atropurpureum Urb. cv. Siratro,Vigna unguiculata (L.) Walp. cv Eureka,Centrosema pubescens Benth cv. Belalto andDesmodium heterocarpon (L) DC.
A significant portion of the native rhizobial isolates were of the fast growing type. Dry matter and total nitrogen production
forM. atropurpureum andV. unguiculata was highest when inoculated with native strains while the commerical strains produced superior dry matter production forC. pubescens andD. heterocarpon. However the total nitrogen production of native and commercial strains was not significantly different for the latter two
legumes.
The study indicated that a potential exists for developing inocula from local Rhizobium strains. |
