Abstract
Effect of Polymeric Additives, Adjuvants, Surfactants on Survival, Stability and Plant Growth Promoting Ability of Liquid Bioinoculants
The present study was conducted to evaluate the effect of polymeric additives, adjuvant and surfactants for their ability to support growth, shelf-life stability and bio-efficacy of liquid bioinoculants (Bacillus megaterium var. phosphaticum, Azospirilum brasilense and Azotobacter chrococcum). Liquid inoculants formulated with 2% polyvinylpyrollidone (PVP 30 K), 0.1% carboxy methylcellulose (CMC-high density) and 0.025% Polysorbate 20 promoted long-term survival of Bacillus megaterium var. phosphaticum, Azospirillum and Azotobacter with 5.6 x 107, 1.9x108 and 3.5x107 cfu ml-1, respectively after 480 days of formulation when stored at 30oC.
