Use of carrier based inoculum for crop growth and yield is wide practice among the conventional agriculture. Precision farming is a site specific management approach. Carrier based inoculum is not suitable for precision farming system due to clogging effect. Hence, liquid bioinoculant's was prepared using N fixer (Azospirillum brasilense), P solubilizer (Bacillus megaterium var. phosphaticum) and PGPR (Pseudomonas fluorescens). The results of the experiment convey that the inoculants supplemented with 10mM of phosphate buffer (pH 7) + 10% glycerol supported maximum survival of Azospirillum (0.17 x 1019 MPN/mL), Bacillus (25 x 1019 cfu/mL) and Pseudomonas (21 x 1019 cfu/mL) at room temperature.
