  <dc:description xml:lang="eng">Abstract: Inoculants containing rhizobial bacteria are bio-inoculants which
represent microbiological N fertilizer and they contain selected highly
effective and highly competitive rhizobial bacteria placed in suitable carrier.
The role of carrier is to maintain the viability and efficiency of bacteria used
as active agent and to increase the shelf life of inoculant. The most
widespread formulation consists of peat as the rhizobia carrier and
formulations of inoculants using zeolites as additives are common.
Nanogranulation of the zeolite by increasing its surface would enhance its
water and nutrients retention efficiency in the layer of the inoculant on
inoculated seeds, making the bacteria more resistant to desiccation causing
nano-carriers superiority over other carriers. In this study, 15 different
inoculants were tested, five highly efficient nitrogen-fixing rhizobial Ensifer
meliloti strains named 218, 225, 252, 4148s and 4193cs in three different
peat carriers, including peat carrier with regular zeolite, zeolite nanoparticles,
or CaCO3. The initial number of rhizobial cells of all strains exceeded 109 in
all formulations. After one month of storage at room temperature the number
did not differ significantly among strains and formulations but after two
months the number was the higher in formulation with zeolite nanoparticles
&gt;1010 for strains 252 and 4148s. This trend continued in the next 6 months.
The nodulation ability and efficiency of inoculants was confirmed in the
nodulation test with alfalfa after three and six months of storage, indicating
good performance of all evaluated inoculant formulations, with the most
performant nano zeolite as an additive.</dc:description>
