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 treatments combination thus formed were laid out in Factorial Randomized Block Design with three replications. The total number of plots was 36. The results showed that the application of 10 t ha-1 sewage sludge singly and in combination with 100% RDF significantly increased the dry matter production at 30, 60 and 90 days growth and growth parameters such as plant height, 1000-grain weight (Test Weight), number of effective tillers and length of panicle. There was significant increase in grain yield of rice with application of sewage sludge. The grain yield of rice is increased by 27.9% at 10 t ha-1 sewage sludge application. 100% RDF application increased the grain yield by 75.4% over control (RDF0). The conjoint application of 10 t ha-1 sewage sludge and 100 % produced the highest grain yield (2306.5 kg ha-1) of rice. Application of 10 t ha-1 sewage sludge significantly improved the concentration and uptake of N, P, K, Zn, Mn, Cu and Fe by the grain. Application of 100% RDF significantly increased N, P and K concentration in grain.

Keywords: Sewage-sludge, RDF, Sodic vertisols, Nutrient uptake.
