Abstract

Onion is one of the most important commercial bulbous crops that grown for regular consumption. Zinc is an essential and important minor key element which makes significant contribution in various physiological and metabolic processes in plants. Inoculation of zinc solubilizing bacteria is recommended to overcome the zinc deficiency in plants and humans. Zinc solubilizing bacteria alone has been found to increase the bioavailability of native and applied zinc to plants. In the present investigations, out of twenty-three soil samples, six isolates of zinc solubilizing bacteria were obtained from different villages of Kolhapur District. All the isolates were identified on the basis of morphological, cultural, microscopic features and biochemical analysis. Most of the isolates showed variability in cell morphology i.e., rod and cocci. Colony colour and shapes also varied i.e., circular, round and irregular. In the biochemical analysis all the isolates showed positive results for catalase test and H2S production test except ZSB-3. All isolates showed positive results for starch hydrolysis, gelatine liquefaction and methyl red test

Conclusion

All ZSB isolates were studied and evaluated efficient isolates on the basis of morphological, cultural, microscopic features, biochemical characterization and solubilisation index. Out of six ZSB isolates, two showed highest solubilising index (5.23) and (4.33) on kings B medium respectively. Efficient isolates ZSB were identified as Bacillus sp. and Pseudomonas sp
