What is the share of each partner in the duties and rights in a potato farming partnership on land owned by one of the partners, given the presence of a water well, but the landowner does not possess a pump to extract its water?

It is permissible for you to provide your land and seeds to someone who will plant potatoes or other crops, on the condition that the produce is shared between you according to an agreement. The worker is responsible for the labor, including plowing, fertilizing, harvesting, and winnowing. The landowner is responsible for building walls, digging canals, installing waterwheels, and purchasing fertilizers. As for the water pump, it is the responsibility of the landowner.
