The indigo cultivators in Bengal were forced to grow indigo on at least 25 per cent of the area under their holdings. The price which they got for their indigo was low. And they had to take loans to repay their previous loans. The indigo crops exhausted the soil fertility rapidly. After an indigo harvest, the land cannot be sown with another crop. All these circumstances lead to "The Blue Rebellion" which broke out in March 1859, which led to the collapse of indigo production in Bengal.
