What is the ruling on a settlement regarding a crop when the land underneath it belongs to the party admitting ownership of the crop?

Primary text

If the land belongs to the acknowledging party, there are two differing views on the validity of the settlement concerning the crop: one view holds that it is valid, and the other holds that it is invalid. This depends on the differing scholarly opinions regarding buying an unripe crop (*zar' akhḍar*) situated on land owned by the buyer.
