Organic manures are known to be rich sources of both macro and micro nutrients of the crop. They also help in improving the physic-chemical status of the soil. In this experiment, the influences of different sources of organic manures and decomposers on the soil physical, chemical as well as biological properties of soil under chilli cultivation soils were investigated. A field experiment was conducted at research and demonstration block of Research Institute on Organic Farming (RIOF), UAS, GKVK, Bengaluru during 2017-2018. Different sources of organic manures (FYM, vermicompost, poultry manure and sheep manure) on N equivalent basis were incorporated into the top 20 cm of soil in line sowing. To determine the effect of the organic sources, the soil samples were collected 1 month after addition of organic manures from depth of 20 cm. The soil physic-chemical properties i.e., pH, EC, bulk density, water holding capacity and organic carbon content were determined. The results showed that application of organic manures and decomposers had significant effect on soil physical and chemical properties like EC, pH, organic carbon, bulk density and water holding capacity as compared to the control, soil treated with organic manures showed apparent increases of organic matter, EC, WHC and reduces bulk density. Irrespective of the decomposers treatments, application of vermicompost on N equivalent basis had recorded significantly higher physic-chemical properties viz., water holding capacity (35.49 per cent), infiltration rate (7.48 cm hr-1), electronic conductivity (0.21 dS m-1) as compared to the other control.
