Description :
In Modern day, intensive crop cultivation requires the use of more chemical fertilizers. The rapid expansion in the field of bacterial genetics had its impact on the study of Nitrogen fixing and phosphate solubilising microorganisms. Zinc is micronutrient and bacteria absorbs it at higher concentration, and its concentration highly affects the lag, exponential and stationary growth of bacteria. The presence of heavy metal influences the uptake of the others nutrients in the soil. Zn- adapted strains of Azotobacter and Bacillus is useful in improving crop as well as fulfills the deficiency of the soil. In present study, both the Zn- strain shows the maximum growth as comparative with wild strain. The height of plant, branches, No. of pods, grain yield and test weight were obtained maximum in metallic strain application.
Keywords- Zinc, Azotobacter, Bacillus and Trigonella
