Does the rent for the part of the land cultivated with citrus differ from the rent for the part cultivated with vegetables from the same land?

Renting out land for a known cash sum is permissible according to most scholars, whether it contains trees or crops. However, renting it out for a portion of its produce is a matter of dispute. It is permissible for the rent to vary depending on what is on the land, so each part has its agreed-upon rent.
