Despite being a major source of livelihood,  rice cultivation in the plains of the north-east region of India is under stress due to depletion of native nutrient reserves, emergence of multi-nutrient deficiencies and  consequent  decline  in  factor  productivity  of  applied  nutrients. With the aim to enhance productivity and to develop efficient fertilizer management strategies for the region, the authors discuss the status of post harvest soil properties and on-farm crop response to plant nutrients in rice-rice sequence under the climatic situation of Lower Brahmaputra Valley Zone of Assam. Results revealed that the recommended dose of NPK fertilizers along with 5 Kg ZnSO4 application not only increases the yield of rice-rice sequence but also enhances the post harvest fertility status of soil.
