A field experiment was conducted in the farmers' field at Kalinarayanpur, Nadia, West Bengal to visualize the effect of integrated nutrient management and integration of makhana (Euryale ferox Salisb.) - cum - fish culture on soil and water characteristics in wetland ecosystem during two consecutive period of pre to post-monsoon season under new alluvial zone of West Bengal. The experiment was laid out in a split plot design having four levels of integrated nutrient management (N1 - Control; N2 - 3 t FYM + 1 t neem oilcake ha-1; N3 - 3 t FYM + 1 t neem oilcake ha-1 + N : P2O5 : K2O @ 20 : 30 : 20 kg ha-1 + spraying of Zn (Chelamin) at 20, 40 and 60 DAT of makhana and N4 - 3 t FYM + 1 t neem oilcake + N : P2O5 : K2O @ 20 : 30 : 20 kg ha-1 + spraying of Zn (Chelamin) at 20, 40 and 60 DAT of makhana + fish-feed) as main plot and five farming systems (F1 - Sole makhana; F2 - Sole live-fishes and F3 - Sole carp fishes @ 6,000 fingerlings ha-1; F4 - Makhana + live-fishes and F5 - Makhana + carp fishes @ 4,500 fingerlings ha-1) as sub-plot treatments with four replications. From the results it reveal that the physico-chemical properties of pond-bottom soil as well as water chrematistics were significantly improved by the integrated nutrient management practices and farming systems as well, except EC. Maximum values of all the soil fertility parameters (organic carbon, organic matter, available N, P and K) and water characterization (pH, BOD, COD, CO3-, HCO3-, NO3-N, SO4-S and Cl-, respectively) were observed in N4 treatment (both plants and fishes received optimum and balance form of organic and inorganic sources of nutrients including fish-feed and spray materials applied at regular intervals) and might be due to the relatively higher accumulation of organic matter by the decomposition of plant residues and residual effect of fertilizers, while, lowest values were exhibited with N1 treatment (control).
