It is possible to boost nutrient accumulation in grain, enhance grain production, and enhance the soil's physical characteristics through the use of bio-fertilizers, zinc delivery methods, and organic and inorganic fertilizers integrated in a balanced manner. Often, zinc (Zn) is insufficient in soil due to a lack of organic matter additions to the soil. The world's food supply is secured by Zn, a crucial micro nutrient. The effect of different zinc application methods and integrated nutrient management methods were tested on wheat crops based on crop production, nutrient uptake, and soil physico-chemical characteristics. Three distinct bio fertilizers, namely Azotobacter, Phosphate solubilizing bacteria, and Zn solubilizing bacteria were used in the experiment. There was a significantly greater number of effective tillers m−2 to the tune of 385 and 388 tillers m−2 and DTPA exchangeable Zn in the final soil of about 0.70 mg/kg with the soil and foliar application of zinc compared with the other treatments. A variety of integrated nutrient management treatments increased crop productivity and soil physico-chemical parameters by increasing soil nutrient availability. The current study indicates that adding organic manure is essential to sustainably preserving soil quality and crop productivity. It should therefore be included in nutrient management plans for crops that require a lot of nutrients.
