Why some unripened fruits are buried in a rice bin?

Question

Farmers who gather mango that are not fully ripe bury them in a rice bin.Why do they do this?

Answer 1

To ripen them enough for selling them.

Answer 2

Mangoes should be ripened at 18 to 23 degrees Celsius.The higher the ripening temperature within this range, the greater the rate of ripening. Relative humidity should be maintained at 90%.Ripening will be slower at the lower temperatures and faster at the higher temperatures within the above stated range.

         Keeping in rice bins provides ideal temperature n humidity.This also prevents the development of rots.
