Nitrogen is the nutrient which limits the most the rice production worldwide. Conjunctive use of organic material along with fertilizer has been proved to be an efficient source of nitrogen. Use of organic manures in conjunction or as an alternative to chemical fertilizer is receiving worldwide attention of the researchers in recent days.. The excessive application of chemical fertilizers made it imperative that a part of inorganic fertilizer may be substituted with the recycling of organic manures. Partial nitrogen substitution through organic manure recording beneficial effect on yield over farmer's practice has been reported by many research workers in rice. This implies for integrated use of organic and inorganic sources of nitrogen for maintaining yield stability. An attempt has been made to review the earlier works on integrated use of organics especially vermicompost, and poultry manure as sources of nitrogen applied with inorganic fertilizers on growth, yield and yield attributing traits in rice In conclusion, integrated application of 50% of nitrogen through inorganic sources with 50% from organic sources is the best combination reported by many workers having beneficial effect on rice yield and improvement of soil properties.
