Abstract: The present study has been carried out at R.B.S. College, Agricultural Research Farm, Bichpuri, Agra during Kharif and Rabi seasons. It is situated at latitude of 2702’ North, longitude of 7709’ East and above of 168 m from mean sea level. Conjoint application of inorganic fertilizers along with Azotobacter chroococcum and farmyard manure play a significant role in sustaining crop productivity and restoring soil fertility. Because of their easy availability and capacity to supply major as well as micronutrients the farmyard manure can supplement the nutritional requirement of the crop. Keeping this in view, field experiments were conducted for two years using Pearl millet and wheat as test crops to study the influence of combined application of FYM, Azotobacter chroococcum and fertilizers on crop productivity and soil fertility. A significant effect of integrated nutrient supply of FYM and fertilizers on organic carbon and microbial biomass carbon content was observed in both crop seasons. Application of FYM alone also improved the buildup of organic carbon and microbial biomass carbon in soil. Similarly, NPK fertilizers also improved the status of organic carbon in soil. The data on the status of organic carbon and microbial biomass carbon in the soil after the harvest of Pearl millet crop in previous year indicate that all the treatments from T2 to T12 increased over the treatment T1 (control). The similar results were also obtained after the harvest of Pearl millet crop in 2nd year.
