Is produce, such as wheat and barley, which is harvested only once, considered to belong to the seller, even if it is green and has not yet produced stalks?

If land is sold with crops on it that are harvested only once, such as wheat and barley, then the crops belong to the seller, whether they are visible or still seeds that have not yet sprouted. This is because they are a visible growth and a deposit in the land, and they remain the property of the seller until harvest. However, if the crop is harvested multiple times, like leeks, then its root is included in the sale of the land. What is visible at the time of sale belongs to the seller, and what appears afterward belongs to the buyer.
