摘要

The on farm trial were laid out in farmers' field of Dakshin Dinajpur district of West Bengal to show the potential of the technology i.e. application of lime in two way, . Lime option 1: Lime application (single dose before stocking of fish) (total dose of lime calculated based on PH of the soil and water), Lime option 2 : Lime application (1/2 of the total dose before stocking of fish) + rest in equal monthly installment(total dose of lime calculated based on PH of the soil and water). The pH of water and soil of the district is acidic in nature. Two technology option on lime application in different frequency were tested, where existing farmers' practice was kept. This study clearly
