Police sources told the Jamaica Observer the sometime last year the child and her mother, who was in a relationship with the farmer, overnighted at his house.
The sources say the farmer forcefully pulled down the child's tights and had sex with her.
Weeks later the child was at the farmer's house alone when, allegedly, he again forced himself on her and had sex with her.
But a recent dispute between the farmer and the girl's mother pushed the child to reveal that she had been raped twice by him.
The name of the farmer is being withheld by the Observer to protect the identity of the child.
