Nodulation and nitrogen fixation in some Desmodium species

Abstract

Effective nodulation of Desmodium uncinatum was obtained by inoculation with Rhizobium isolated from D. intortum and Glycine javanica, but no nodules were formed with isolates from Glycine tabacina, Stylosanthes humilis, Arachis hypogaea or Lespedeza striata. Three reputedly highly efficient strains of Rhizobium on Desmodium were tested for nitrogen fixation in five species of Desmodium. The host spectrum of effective association varied.
