On the basis of the following reviews it may be inferred that combined use of organic and inorganic sources of N has resulted in better rice yield than inorganic source alone. So also their residual effect boosted the productivity of succeeding crop. Thus integrated use of organic and inorganic fertilizers are effective in enhancing the productivity of the cropping system. Besides, it has beneficial influence on physico-chemical properties of the soil in respect of lowering bulk density and pH and improving the organic carbon as well as available nutrient status of soil in general and N in particular apart from improving N use efficiency in rice-based cropping systems.
