PPF vs debt mutual fund?


Why do people suggest investing in a debt mutual fund instead of public provident fund? I see lot of people investing in debt funds to protect their risk from equity investments.

PPF consistently gives 8% return and it is far better than a most of the debt mutual funds in India.

Is it only because of liquidity reason?
