Grain and straw yield of wheat increased with the application of sewage sludge and P. The interaction of sewage sludge and P on the grain yield of wheat was not significant. Total P and N uptake by wheat increased with the increased application of sewage sludge and P. Organic carbon content and Olsen extractable P of post-harvest soil samples increased with the application of sewage sludge. But P application increased only Olsen's P and soil carbon remained unaffected.
