The field study took place at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology And Sciences, Prayagraj (U.P. ), India, during the Rabi season of 2022. To research how Zinc Sulphate and Bio-fertilizers affect the production and growth of Maize. PSB, Azotobacter, PSB + Azotobacter, and Zinc Sulphate 20, 25, and 30 kg/ha make up the treatments. The soil on the experimental plot had a sandy loamy texture, had a pH of 7.8, and had little organic carbon (0.35%). The results showed that the greater plant height (159.03 cm), plant dry weight (162.70 g/plant), crop growth rate (64.12 g/m2/day), number of cobs per plant (1.8), number of rows per cob (16.8), number of seeds per cob (553.4),  higher 100 seed weight (29.3 gm), higher Grain yield (6.5 t/ha) higher straw yield (12.9 t/ha), and Harvest index (33.8) were significantly influenced with  the application of PSB  + Azotobacter + Zinc Sulphate 30 kg/ha.
