Alkaline phosphatase (E.C. is an extracellular enzyme which plays an important role in releasing of phosphorus from sediment which is an essential nutrient for sustaining primary and secondary productivity. It also acts as an indicator of environment pollution. In this present research work which is the first of its kinds, the relationship between alkaline phosphatase activity of the sediment with the various soil physicochemical parameters along with total bacterial count was worked out. For these a total of 20 bulk sediment samples were collected randomly from different sites of the brackish water systems of the east India and processed to determine alkaline phosphatase activity, total bacterial count and other soil physicochemical parameters. Descriptive and inferential statistics were used to analyze the data. It can be inferred from this study that the alkaline phosphatase activity in brackish water systems is influenced by the different soil physicochemical parameters and bacterial population.
