A field experiment was carried out at Agronomy Research Farm, Central Research Station, Odisha University of Agriculture and Technology, Bhubaneswar, Odisha, during both kharif and rabi seasons of 2015-16 and 2016-17, to find out the suitable organic nutrient management practice for higher productivity, and maintenance of soil fertility in scented rice-rice sequence. Application of recommended dose of fertilizer to Scented rice- rice sequence (Geetanjali) produced higher grain yield but similar yield also obtained from the sequence grown with 100% RDN through poultry manure along with top dressing with liquid manure twice at 25 and 50 DAT and soil health also maintained properly The maximum organic carbon (0.63%), available N (296.87kg/ha), available P (62.94kg/ha), available K (189.23kg/ha) was recorded with the same treatment which ultimately induced the content and uptake of nutrients. Comparatively lesser gain in soil NPK after completion of the two-year sequence was noticed in fully inorganic treatment as compared to the organic treatments. However, negative balance in NPK was observed when no fertilizer or manures were applied to all the rice crops in sequence. Similarly mining of potassium was also noticed when FYM was used as one of the source of organic nutrient management in scented rice-rice sequence.
