Description An investigation was carried out to prepare a novel fluid bed
dried (FBD) inoculant formulation containing microbial consortium
and study survival of constituent microorganisms Pseudomonas
fluorescens, Acinetobacter sp. and Azotobacter chroococcum in different
consortial combinations up to 180 days. Growth curves determined
revealed that stationary phases were 48 h, 24 h and 72 h for P.
fluorescens, Acinetobacter sp. and A. chroococcum respectively. Survival
of these microorganisms was highest in triple inoculant consortium in
talc. A dual inoculant consortium of P. fluorescens and A. chroococcum
recorded higher number of cells initially. Per cent survival of cells on
log values was recorded highest in triple inoculant formulation
followed by dual and single inoculant formulations. No contamination
was recorded from all FBD inoculant formulation by the end of 180
days at 10-5 dilution. Effectiveness study of these inoculant
formulations was carried out in finger millet (Eleusine coracana
Gaertn.) in a green house investigation. This study revealed maximum
number of leaves, plant height, nitrogen content, phosphorus content,
root dry weight, shoot dry weight, and total dry weight in plants
receiving triple inoculant consortium followed by dual, single and
uninoculated control. Chlorophyll content was highest from plants
containing dual inoculant consortium of P. fluorescens + Acinetobacter
sp. and Acinetobacter sp. + A. chroococcum and least was observed in
uninoculated plants. Results were more pronounced when inoculation
done along with nutrient (+NPK) than without nutrient (-NPK).
Performance of plants receiving triple inoculant consortium without
nutrients was on par with uninoculated plants with nutrients.
