Abstract: Physico-chemical properties and soil biologia are the life line of soils. It is the microbial population and its role in crop production give soil on adjective of living substance. Application of organic manure either as a full dose or half dose caused CEC (85.25me/100g soil) and organic carbon (0.76%) percentage to increase from the initial values of 0.75me/100g soil and 0.54%, respectively. Available potash content, however, was a bit higher in treatment receiving full dose in inorganic form. Water holding capacity (20.63%) and mean wet diameter (8.46mm) were the highest and electrical conductivity was the lowest (0.31mmhos/dsm) in the treatment receiving 100% nutrition in organic manure form as against corresponding initial values of 17.8%, 4.65mm and 0.34 mmhos/dsm. Microbial population too were the maximum in plots supplicated with 100% nutrition in organic form. In this treatment population of bacteria, fungi and actinomyceties were found 8.53x10⁶, 3.82x10⁵, and 8.03 X10⁵ against initial value of 69x10⁶, 2.8x10⁵ and 6.2x10⁵.
