ABSTRACT

Biostimulants are materials that reduce the need of fertilizers and promote plant growth when applied in low quantities. Biostimulant also helps growth in resistance of water and abiotic stress. Present studty focussed on the isolation, Characterizatiion of Biostimulant (Azospirillum, Potassium solubilising bacteria and Phosphate solublizing bacteria fromdifferent soils including neem soil, coconut soil, hibiscus soil, gooseberry soil and banana soil and application of biostimulants under different abiotic stress and plant growth characteristics. The isolated biostimulants from soil bacteria provides better results under different abiotic stress.

Keywords: Biostimulants, Abiotic stress.
