The bananas do not have a plantation?
The citrus looks fine. You are on a hill = 2 hammers. It's citrus so it's +1 gold and +1 food for the base tile too (can't recall having citrus seen on hills before though, u be using mods or a special map?).
Now the plantation gives another +1 gold. That is all a plantation does (except on bananas, there it's +2 food instead iirc) (only after fertilizer a plantation gains another +1 food).
