Journal ArticleDOI
Inoculant quality and its evaluation
Newton Z. Lupwayi,Perry E. Olsen,E.S Sande,H.H Keyser,Mandy M. Collins,P.W Singleton,W. A. Rice +6 more
TL;DR: It is desirable that the quality of legume inoculant be protected by some form of governmental regulation because many manufacturers are unable or unwilling to institute or enforce rigorous internal quality control procedures.
Journal ArticleDOI
Biological contaminants in North American legume inoculants
TL;DR: A survey of 40 commercial North American rhizobial inoculants was made to determine the number of contaminant cells relative to rhizOBial cells, finding only one inoculant contained more rhizobia (Rhizobium or Bradyrhizobia spp) than contaminants.
Journal ArticleDOI
Rhizobium population dynamics in the pea rhizosphere of rhizobial inoculant strain applied in different formulations.
Russell K. Hynes,Desirée C. Jans,Eric Bremer,Newton Z. Lupwayi,W. A. Rice,George W. Clayton,Mandy M. Collins +6 more
TL;DR: The effect of inoculant formulation on the population dynamics of rhizobia in the pea rhizosphere was investigated using a streptomycin-resistant mutant of Rhizobium leguminosarum bv.
Journal ArticleDOI
Levels and identities of nonrhizobial microorganisms found in commercial legume inoculant made with nonsterile peat carrier
TL;DR: Sixty samples of commercial North American legume inoculants manufactured for sale in 1994 using nonsterile peat as carrier were tested for Rhizobium (or Bradyrhizobia) content and non-Rhizobial biological contaminant load.
Journal ArticleDOI
Symbiotic effectiveness of Rhizobium meliloti at low root temperature
TL;DR: In this paper, a variety of Rhizobium meliloti isolates were evaluated for the ability to grow, nodulate alfalfa (Medicago sativa L.) and support plant growth between 9° and 12°C.
