Abstract: Field experiment was carried out during the period of 2000-01 to 2002-03 at Aclisaptagram Block Seed Farm, Hooghly, West Bengal to study the effect of organic and inorganic sources of nutrient for sustaining productivity and soil fertility under potato-okra-paddy rotations. Maximum tuber yield (285.40 q ha -1) of potato and grain yield (43.20 q ha-1 ) of paddy were obtained where both potato and paddy crops were fertilized with 125 % of the recommended dose of N, P and K along with 10 t FYM ha-1 Okra grown on residual fertility of previous crop was exhibited higher yield with 125%, 100% and 75% of the recommended dose of N, P and K to potato in conjunction with 10 t FYM ha-1 The nutrient uptake and the soil nutrient status were also improved with the combined application of organic and Inorganic sources of nutrients. Application of 10 t FYM ha-1 to potato and paddy along with 75% of the recommended dose of N, P and K appeared to be moreremunerative than N, P and K as inorganic sources only.
