The present studies (2000–2001) were carried out on the twelve years old long-term fertilizer experiment. The fourteen treatments comprised of NPK levels with and without FYM, Sand Zn. The results indicafed that the soil properties such as organic carbon, total N, P, S and available NPK and S favourably influenced by the conjunctive use of organic and inorganics, Highest values were observed in the treatment of 100% NPK + lOt FYM ha/t. The influence on soil properties ultimately reflected in higher yield of sorghum and wheat in the same treatment. It is also observed that the soil properties were significantly correlated with yield. Hence, it can be concluded that the use of IPNS is imperative for sustainable productivity and maintenance of soil fertility.
