Farming economy (9)
I believe the answer is:
husbandry
I believe this clue is a double definition.
'farming' is the first definition.
('husbandry' can be a synonym of 'farming')
'economy' is the second definition.
(I've seen this before)
(Other definitions for husbandry that I've seen before include "farming task" , "The business of farming" , "The care of crops and animals" , "Farm business" , "Economy" .)
