Raising the issue in the assembly, she said a crisis had emerged where the farmers were not able to purchase potato seeds owing to the demonetisation.
This was not the time for political fights, she said and urged the opposition parties to give suggestions on how to deal with the crisis.
Banerjee said all kind of farming activity had been stopped and the common man had been hit hard by demonetisation.
In this hour of crisis, there is a need to stand by the farmers, she added.
