Money

Yield: about 14 quintals an acre, the typical figure in your state (its government crop records list none for your district).

A new planting gives its first real harvest after about 6 years. The money here is for plants already bearing.

On rain alone it gets about 70% of the water it needs, so the money here is worked at 70% of this yield.
