EFFECTIVENESS OF RHIZOBIA - LEGUME ASSOCIATIONS
Effectiveness of rhizobia-legume associations in dinitrogen fixation depend on susceptibility of the host legume to nodulation, infection by an effective strain of Rhizobium and conditions favorable for plant growth.

Abstract
Effectiveness ratings of rhizobial strains are confounded by variability in host genotype, variability in rhizobial culture, number of inoculated rhizobia, mineral nutrition and photosynthetic process, all of which are usually indicated by dry matter production. Response of legume production to N fertilization indicates opportunity to improve effectiveness of the association. Proper rhizobia-legume associations can apparently obtain from N2 all the N needed to match photosynthetic activity. Research is needed to provide and maintain proper associations for all legume crops, and to achieve adequate inoculation where needed.
