ABSTRACT
A field experiment was conducted at salinity Research farm, Barwaha, District Khargone, Madhya Pradesh during kharif season of 2014-15. The experiment comprised of 3 levels of sewage sludge (0, 5 and 10 t ha-1) and 4 levels of fertility levels (0, 75, 100 and 125% RDF). Twelve treatment combination thus formed were laid out in Factorial Randomized Block Design with three replications. The total number of plots was 36. Addition of 10 t ha-1 sewage sludge slightly decreased pHs, ESP and increased the ECe of post-harvest sodic Vertisols. Increase in available nutrient status (N, P, K Zn, Mn, Cu and Fe) of soil was also recorded with increasing levels of sewage sludge application after harvest of rice. Application of 100% RDF also improved only the available status of N, P and K of sodic Vertisols at harvest. Application of sewage sludge may have save 25% of chemical fertilizers (RDF) as 125% RDF is recommended for sodic Vertisols.
