ABSTRACT
This article reports comparitive performance of different organic and inorganic sources of N for wheat and rice rotation.The fertilizer proved to be the best source of N for the first crop i.e., wheat while it had a very poor residual effect on the following rice crop. In contrast the organic sources did not proved good for wheat crop but their residual effect on the coming rice crop was better than that of the fertilizer treatment. Among the organic sources, the farm yard manure proved to be the best of all followed by green manure. It may be concluded from these results that nutrients in the organic residues and manures take time to become available for the plants and therefore these must be added to soil well in time before the crop sowing .
