In the last thirty years, numerous scientific revolutions have been planned to improve the ecological balance of agricultural production methods, via a considerable decrease of inorganic compounds like pesticides, synthetic plant growth hormones and fertilizers. A favorable and environment sustainable modernization should be the practice of normal plant biostimulants (PBs) which augment flowering, plant evolution, fruit formation, crop output and efficient nutrient mobilization, and ability to endure a varied array of abiotic stressors. PBs was primarily deciphered via exclusive of various functions similar to fertilizers or plant protection by-products. They are assorted constituents and microbes resorted to boost plant development. This review aimed to present the plant biostimulants definition, major classifications, and impacts on floras, soil and ecology.

In this study, isolation and characterization of potassium solubilizing bacteria (KSB) have been carried out which could solubilize a substantial amount of potassium (K) following incubation with mica. Five KSB, isolated from banana and chilli rhizosphere were identified by 16S rDNA sequence analysis. The identified bacteria were Klebsiella sp. and Bacillus cereus. The isolates had K solubilization potential within the range of 76.3-78.42% compared to control along with significant drop in pH (4.62-4.86). The study reveals the exploitation of Klebsiella sp. and B. cereus as potential K solubilizing biofertilizers.
